Safety instructions 1

CAUTION Transportation and installation The temporary storage temperature (applicable to a short limited

time such as a transportation time) must be between -20 and +65C. Otherwise this product may be damaged. This product must be used indoors (without corrosive gas,

flammable gas, oil mist, dust and dirt etc.) Otherwise the product may be damaged. Do not use this product at an altitude above 2500 m. Vibration

should not exceed 2.9 m/s2 at 10 to 55 Hz in X, Y, and Z directions. Otherwise the product may be damaged. (For installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.) (Refer to page 20 for details.) If halogens (including fluorine, chlorine, bromine, and iodine)

contained in fumigants for wood packages enter this product, the product may be damaged. Prevent the entry of fumigant residuals or use an alternative method such as heat disinfection. Note that sterilization or disinfection of wood packages should be performed before packing the product.

Wiring Do not install a power factor correction capacitor, surge

absorber, or radio noise filter on the output side of this product. These devices may overheat or burn out. The output terminals (terminals U, V, and W) must be connected

to a motor correctly. Otherwise the motor will rotate inversely. Trial run Before starting the test operation, confirm or adjust the

parameter settings. Failure to do so may cause some machines to make unexpected motions.

WARNING Usage Stay away from the equipment after using the retry function in

this product as the equipment will restart suddenly after the output shutoff of this product. Depending on the function settings of this product, the product

does not stop its output even when the STOP/RESET key on the operation panel is pressed. To prepare for it, provide a separate circuit and switch (to turn OFF the power of this product, or apply a mechanical brake, etc.) for an emergency stop. Be sure to turn OFF the start (STF/STR) signal before clearing

the fault as this product will restart the motor suddenly after a fault is cleared. Use only a three-phase induction motor as a load on this

product. Connection of any other electrical equipment to the output of this product may damage the equipment. Performing pre-excitation (LX signal and X13 signal) under

torque control (Real sensorless vector control) may start the motor running at a low speed even when the start command (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low speed when the speed limit value is set to zero. Confirm that the motor running will not cause any safety problems before performing pre-excitation. Do not modify this product. Do not perform parts removal which is not instructed in this

manual. Doing so may lead to fault or damage of this product.

CAUTION Usage The electronic thermal O/L relay function may not be enough for

protection of the motor from overheating. It is recommended to install an external thermal relay or a PTC thermistor for overheat protection. Do not repeatedly start or stop this product with a magnetic

contactor on its input side. Doing so may shorten the life of this product. Use a noise filter or other means to minimize the

electromagnetic interference with other electronic equipment used nearby this product. Appropriate precautions must be taken to suppress harmonics.

Otherwise power harmonics from this product may heat/damage a power factor correction capacitor or a generator. To drive a 400 V class motor with this product, use an insulation-

enhanced motor, or take measures to suppress surge voltage. Otherwise surge voltage, which is attributed to the length and thickness of wire, may occur at the motor terminals, causing the motor insulation to deteriorate. As all parameters return to their initial values after the Parameter

clear or All parameter clear is performed, the parameters must be set again as required before the operation is started. This product can be easily set for high-speed operation.

Therefore, consider all things related to the operation such as the performance of a motor and equipment in a system before the setting change. This product's brake function cannot be used as a mechanical

brake. Use a separate device instead. Perform an inspection and test operation of this product if it has

been stored for a long period of time. To avoid damage to this product due to static electricity, static

electricity in your body must be discharged before you touch this product. In order to protect this product and the system against

unauthorized access from external sources through Ethernet communication, take security measures such as setting up a firewall. Depending on the Ethernet network environment, this product

may not operate as intended due to delays or disconnection in communication. Carefully consider what type of environment this product will be used in and any safety issues related to its use.

Emergency stop A safety backup such as an emergency brake must be provided

for devices or equipment in a system to prevent hazardous conditions in case of failure of this product or an external device controlling this product. If the breaker installed on the input side of this product trips,

check for wiring faults (short circuits etc.) and damage to internal parts of this product. Identify and remove the cause of the trip before resetting the tripped breaker and applying the power to the product again. When any protective function is activated, take an appropriate

corrective action before resetting this product to resume the operation.

Maintenance, inspection and parts replacement Do not carry out a megger (insulation resistance) test on the

control circuit of this product. Doing so will cause a failure. Disposal This product must be treated as industrial waste.

2.1 Peripheral devices

2.1.1 Inverter and peripheral devices

NOTE To prevent an electric shock, always earth (ground) the motor, the inverter, and the converter unit. Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side. Doing

so will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is connected, immediately remove it. When installing a molded case circuit breaker on the output side of the inverter, contact the manufacturer of the molded case circuit breaker.

Electromagnetic wave interference The input/output (main circuit) of the inverter or the converter unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter or the converter unit. In this case, activating the EMC filter of the converter unit may minimize interference. (Refer to page 78.)

The life of the inverter and the converter unit is influenced by the surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. Incorrect wiring may lead to damage of the inverter and the converter unit. The control signal lines must be kept fully away from the main circuit lines to protect them from noise. The converter unit built-in EMC filter can reduce the noise.

20 27 78

(b) Converter unit (FR-CC2)

(c) Three-phase AC power supply Must be within the permissible power supply specifications of the converter unit. 110

(d) Molded case circuit breaker (MCCB), earth leakage circuit breaker (ELB), or fuse

Must be selected carefully since an inrush current flows in the converter unit at power ON. 16

(e) Magnetic contactor (MC) Install this to ensure safety. Do not use this to start and stop the inverter. Doing so will shorten the life of the inverter and the converter unit.

83

(f) AC reactor (FR-HAL)

Install this to suppress harmonics and to improve the power factor. An AC reactor (FR-HAL) (option) is required when installing the inverter near a large power supply system (1000 kVA or more). Under such condition, the inverter and the converter unit may be damaged if you do not use a reactor. Select a reactor according to the applied motor capacity.

82

(g) Noise filter Suppresses the noise radiated from the power supply side of the converter unit. 75

(h) High power factor converter (FR-HC2) Suppresses the power supply harmonics significantly. Install these options as required. When FR-HC2 is used, FR-CC2 is not required.

67

(i) Brake unit (FR-BU2) Allows the inverter to provide the optimal regenerative braking capability. Install these options as required. 66

(j) Resistor unit (MT-BR5)

(k) USB connection A USB (Ver. 1.1) cable connects the inverter with a personal computer. A USB memory device enables parameter copies and the trace function. 57

(l) Noise filter Install this to reduce the electromagnetic noise generated from the inverter and the converter unit. The noise filter is effective in the range from about 0.5 MHz to 5 MHz.

Installation of the inverter and enclosure design

2.3 Installation of the inverter and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.

2.3.1 Inverter installation environment The following table lists the standard specifications of the inverter installation environment. Using the inverter in an environment that does not satisfy the conditions deteriorates the performance, shortens the life, and causes a failure. Refer to the following points, and take adequate measures.

Standard environmental specifications of the inverter

1 Temperature applicable for a short time, e.g. in transit. 2 For the installation at an altitude above 1000 m, derate the rated current 3% per 500 m.

Temperature The permissible surrounding air temperature of the inverter is between -10C and +50C (-10C and +40C at the SLD rating). Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures to keep the surrounding air temperature of the inverter within the specified range. (a) Measures against high temperature Use a forced ventilation system or similar cooling system. (Refer to page 22.) Install the enclosure in an air-conditioned electric chamber. Block direct sunlight. Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source. Ventilate the area around the enclosure well. (b) Measures against low temperature Provide a space heater in the enclosure. Do not power OFF the inverter. (Keep the start signal of the inverter OFF.) (c) Sudden temperature changes Select an installation place where temperature does not change suddenly. Avoid installing the inverter near the air outlet of an air conditioner. If temperature changes are caused by opening/closing of a door, install the inverter away from the door.

Humidity Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown. The insulation distance defined in JEM 1103 "Control Equipment Insulator" is humidity of 45 to 85%.

(a) Measures against high humidity Make the enclosure enclosed, and provide it with a hygroscopic agent. Provide dry air into the enclosure from outside. Provide a space heater in the enclosure. (b) Measures against low humidity Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge your body (static electricity) beforehand, and keep your body away from the parts and patterns. (c) Measures against condensation Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air temperature changes suddenly. Condensation causes such faults as reduced insulation and corrosion. Take the measures against high humidity in (a). Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

Dust, dirt, oil mist Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time. Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasure Place the inverter in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 22.) Purge air.

Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.

Corrosive gas, salt damage If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the relays and switches will result in poor contact. In such places, take the measures given above.

Explosive, flammable gases As the inverter is non-explosion proof, it must be contained in an explosion-proof enclosure. In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to avoid installation in such places and install the inverter in a non-hazardous place.

High altitude Use the inverter at an altitude of within 2500 m. For use at an altitude above 1000 m, derate the rated current 3% per 500 m. If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength.

Vibration, impact The vibration resistance of the inverter is up to 2.9 m/s2 at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values. Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.

Precautions Provide the enclosure with rubber vibration isolators. Strengthen the structure to prevent the enclosure from resonance. Install the enclosure away from the sources of the vibration.

Installation of the inverter and enclosure design

2.3.2 Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter. The cooling systems are classified as follows in terms of the cooling calculation method. (a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type) (b) Cooling by heat sink (aluminum fin, etc.) (c) Cooling by ventilation (forced ventilation type, pipe ventilation type) (d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

Cooling system Enclosure structure Comment

Natural

Natural ventilation (enclosed type / open type)

This system is low in cost and generally used, but the enclosure size increases as the inverter capacity increases. This system is for relatively small capacities.

Natural ventilation (totally enclosed type)

Being a totally enclosed type, this system is the most appropriate for hostile environment having dust, dirt, oil mist, etc. The enclosure size increases depending on the inverter capacity.

Forced air

Heat sink cooling This system has restrictions on the heat sink mounting position and area. This system is for relatively small capacities.

Forced ventilation This system is for general indoor installation. This is appropriate for enclosure downsizing and cost reduction, and often used.

2.3.3 Inverter installation Inverter placement

Install the inverter on a strong surface securely with screws. Leave enough clearances and take cooling measures. Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity. Install the inverter on a nonflammable wall surface. When encasing multiple inverters in an enclosure, install them in parallel as a cooling measure. For heat dissipation and maintenance, keep clearance between the inverter and the other devices or enclosure surface.

The clearance below the inverter is required as a wiring space, and the clearance above the inverter is required as a heat dissipation space.

When designing or building an enclosure for the inverter, carefully consider influencing factors such as heat generation of the contained devices and the operating environment.

1 There needs to be a space of at least 30 cm in front of the inverter to replace the cooling fan. Refer to page 102 for fan replacement.

Installation orientation of the inverter Install the inverter on a wall as specified. Do not mount it horizontally or in any other way.

Above the inverter Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant.

Arrangement of the ventilation fan and inverter

When multiple inverters and converter units are placed in the same enclosure, arrange them horizontally as shown in the figure on the right. Do not place multiple products vertically. The exhaust air temperature of the inverter and the converter unit may be increased.

When mounting multiple inverters and converter units, fully take caution not to make the surrounding air temperature of the inverter and the converter unit higher than the permissible value by providing ventilation and increasing the enclosure size.

Arrangement of multiple inverters and converter units

Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air.)

2 The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189). 3 Terminal JOG is also used as the pulse train input terminal. Use Pr.291 to choose JOG or pulse. 4 The X10 signal (NC contact input specification) is assigned to the terminal MRS in the initial setting. Set Pr.599 = "0" to change the input

specification of the X10 signal to NO contact. 5 Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage (0 to 5 V/0 to 10 V), set

the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used as a PTC input terminal. (Pr.561)

6 It is recommended to use 2 W 1 k when the frequency setting signal is changed frequently. 7 The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196). 8 The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). 9 No function is assigned in the initial setting. Use Pr.192 for function assignment. 10 The terminal FM can be used to output pulse trains as open collector output by setting Pr.291. 11 Not required when calibrating the scale with the operation panel.

NOTE To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the

main circuit cables at the input side from the main circuit cables at the output side. After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter.

Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.

Use Pr.291 to choose JOG or pulse. 4 The X10 signal (NC contact input specification) is assigned to terminal MRS in the initial setting. Set Pr.599 = "0" to change the input

specification of the X10 signal to NO contact. 5 Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage (0 to 5 V/0 to 10 V), set

the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used as a PTC input terminal. (Pr.561)

6 It is recommended to use 2 W 1 k when the frequency setting signal is changed frequently. 7 The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196). 8 The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). 9 No function is assigned in the initial setting. Use Pr.192 for function assignment.

NOTE To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the

main circuit cables at the input side from the main circuit cables at the output side. After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter.

Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.

Connection between the converter unit and the inverter Perform wiring so that the commands sent from the converter unit are transmitted to the inverter without fail. Incorrect connection may damage the converter unit and the inverter. For the wiring length, refer to the table below.

For the cable gauge of the cable across the main circuit terminals P/+ and N/- (P and P, N and N), refer to page 38.

1 Do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-). Connecting the opposite polarity of terminals N/- and P/+ will damage the inverter.

2 For the terminal used for the X10 signal input, set "10" in any of Pr.178 to Pr.189 (input terminal function selection) to assign the function. (The X10 signal is assigned to terminal MRS in the initial setting.) For the X10 signal, NC contact input specification is selected in the initial setting. Set Pr.599 = "0" to change the input specification to NO contact.

3 For the terminal used for the X11 signal input, set "11" in any of Pr.178 to Pr.189 (input terminal function selection) to assign the function. For RS-485 or any other form of communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the time of an instantaneous power failure.

4 Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of the converter unit and the terminal SD (sink logic) of the inverter. Not connecting these terminals may damage the converter unit.

Total wiring length Connect one or more general-purpose motors within the total wiring length 500 m. (The wiring length should be 100 m or less under vector control.)

When driving a 400 V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. In this case, take one of the following measure. Use a "400 V class inverter-driven insulation-enhanced motor" and set Pr.72 PWM frequency selection according to

the wiring length.

If the motor capacity is 280 kW or lower, connect the sine wave filter (MT-BSL/BSC) to the output side.

NOTE Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the

wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function or a malfunction or fault of the equipment connected on the inverter output side. If the fast-response current limit function malfunctions, disable this function. (For the details of Pr.156 Stall prevention operation selection, refer to the FR-A800 Instruction Manual (Detailed))

A sine wave filter (MT-BSL/BSC) can be used under V/F control. Do not use the filters under different control methods. For the details of Pr.72 PWM frequency selection, refer to the FR-A800 Instruction Manual (Detailed). Refer to page 84 to drive a 400 V class motor by an inverter.

2.5.5 Earthing (grounding) precautions Always earth (ground) the motor, the inverter, and the converter unit.

Purpose of earthing (grounding) Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use. An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current flows into the case. The purpose of earthing (grounding) the case of an electrical apparatus is to prevent operators from getting an electric shock from this leakage current when touching it. To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast.

Earthing (grounding) methods and earthing (grounding) work As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise- influenced malfunction prevention type. Therefore, these two types should be clearly distinguished, and the following work must be done to prevent the leakage current having the inverter's high frequency components from entering the malfunction prevention type earthing (grounding): Whenever possible, use the independent earthing (grounding) for the inverter.

If independent earthing (grounding) (I) is not available, use (II) common earthing (grounding) in the figure below where the inverter is connected with the other equipment at an earthing (grounding) point. Do not use the other equipment's earthing (grounding) cable to earth (ground) the inverter as shown in (III). A leakage current containing many high frequency components flows into the earthing (grounding) cables of the inverter and peripheral devices. Because of this, the inverter must be earthed (grounded) separately from EMI-sensitive devices. In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.

(NEC section 250, IEC 61140 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply in compliance with EN standard must be used.

use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should be the size indicated in the table on page 38.

The earthing (grounding) point should be as close as possible to the inverter, and the earth (ground) wire length should be as short as possible.

Run the earthing (grounding) cable as far away as possible from the I/O wiring of equipment sensitive to noises and run them in parallel in the minimum distance.

NOTE To be compliant with the EU Directive (Low Voltage Directive), refer to page 117.

By setting Pr.75, reset can be enabled only at an inverter fault occurrence. The inverter recovers about 1s after the reset is released.

AU Terminal 4 input selection

The terminal 4 function is available only when the AU signal is ON Turning ON the AU signal disables the terminal 2 function.

CS

Selection of automatic restart after instantaneous power failure

When the CS signal is left ON, the inverter restarts automatically at power restoration. Note that restart setting is necessary on both the inverter and the converter unit for this operation. In the initial setting, a restart is disabled.

Wiring method Power supply connection Use crimp terminals and stripped wire for the control circuit wiring. For single wire, the stripped wire can be used without crimp terminal. Connect the end of wires (crimp terminal or stranded wire) to the terminal block.

(1) Strip the signal wires as shown below. If too much of the wire is stripped, a short circuit may occur with neighboring wires. If not enough of the wire is stripped, wires may become loose and fall out. Twist the stripped end of wires to prevent them from fraying. Do not solder it.

(2) Use appropriate crimp terminals (ferrules, blade terminals, etc.). Insert wires to the crimp terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the crimp terminals after crimping. Do not use the crimp terminals of which the crimping is inappropriate, or the face is damaged.

Control circuit

Signal inputs by contactless switches The contact input terminals of the inverter (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled using a transistor instead of a contact switch as shown below.

2.6.5 Wiring precautions It is recommended to use a cable of 0.75 mm2 for the connection to the control circuit terminals. The wiring length should be 30 m (200 m for terminal FM) at the maximum. Use two or more parallel micro-signal contacts or twin contacts to prevent

contact faults when using contact inputs since the control circuit input signals are micro-currents.

To suppress EMI, use shielded or twisted cables for the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common terminal of the connected control circuit terminal. When connecting an external power supply to terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth (ground) the shield to the enclosure, etc.

Always apply a voltage to the fault output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc. Separate the wiring of the control circuit away from the wiring of the main circuit.

Cable gauge: 0.75 mm2 to 2 mm2

Tightening torque: 1.5 Nm

Connected to When a fault occurs, opening of the electromagnetic contactor (MC) on the inverter power supply side results in power loss in the control circuit, disabling the fault output signal retention. Terminals R1/L11 and S1/L21 are provided to hold a fault signal. In this case, connect the power supply terminals R1/L11 and S1/L21 of the control circuit to the input side of the MC. Terminals R1/L11 and S1/L21 are connected to terminals P/+ and N/- with a jumper respectively. Do not connect the power cable to incorrect terminals. Doing so may damage the inverter.

(a) Remove the upper screws. (b) Remove the lower screws. (c) Pull the jumper toward you to remove. (d) Connect the separate power supply cable for the control circuit to the upper terminals (R1/L11, S1/L21).

NOTE When using separate power supplies, always remove the jumpers from terminals R1/L11 and S1/L21. The inverter may be

damaged if the jumpers are not removed. The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than

the input side of the MC. The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 is 80 VA. If the main circuit power is switched OFF (for 0.1 s or more) then ON again, the inverter is reset and a fault output will not be

held.

2.6.7 When supplying 24 V external power to the control circuit

Connect a 24 V external power supply across terminals +24 and SD. Connecting a 24 V external power supply enables I/O terminal ON/OFF operation, operation panel displays, control functions, and communication during communication operation even during power-OFF of inverter's main circuit power supply. When the main circuit power supply is turned ON, the power supply changes from the 24 V external power supply to the main circuit power supply.

Specification of the applied 24 V external power supply

Commercially available products (as of April 2019)

1 For the latest information about OMRON power supply, contact OMRON corporation.

Starting and stopping the 24 V external power supply operation Supplying 24 V external power while the main circuit power is OFF starts the 24 V external power supply operation.

Likewise, turning OFF the main circuit power while supplying 24 V external power starts the 24 V external power supply operation.

Turning ON the main circuit power stops 24 V external power supply operation and enables the normal operation.

NOTE When 24 V external power is supplied while the main circuit power supply is OFF, the inverter operation is disabled. In the initial setting, when the main power supply is turned ON during the 24 V external power supply operation, a reset is

performed in the inverter, then the power supply changes to the main circuit power supply. (The reset can be disabled using Pr.30.)

Confirming the 24 V external power supply input During 24 V external power supply operation, "EV" flashes on the operation panel. The alarm LED also flashes. Thus, the

24 V external power supply operation can be confirmed even when the operation panel is removed.

During the 24 V external power supply operation, the 24 V external power supply operation (EV) signal is output. To use the EV signal, set "68 (positive logic) or 168 (negative logic)" in one of Pr.190 to Pr.196 (output terminal function selection) to assign function to an output terminal.

Operation while the 24 V external power is supplied Fault records and parameters can be read and parameters can be written (when the parameter write from the operation

panel is enabled) using the operation panel keys. The safety stop function is disabled during the 24 V external power supply operation. During the 24 V external power supply operation, monitored items and signals related to inputs to main circuit power supply,

such as output current and converter output voltage, are invalid. The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power supply is

changed to the 24 V external power supply. Perform the inverter reset or turn OFF then ON the power to reset the faults. The output data is retained when "1 or 11" is set in Pr.495 Remote output selection.

NOTE Inrush current equal to or higher than the 24 V external power supply specification may flow at power-ON. Confirm that the

power supply and other devices are not affected by the inrush current and the voltage drop caused by it. Depending on the power supply, the inrush current protection may be activated to disable the power supply. Select the power supply and capacity carefully.

When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the appropriate wiring size and length to keep the voltage in the rated input voltage range.

In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power supply. The increase of the current causes voltage to drop further. Use the inverter after confirming that the input voltage of each converter unit is within the rated input voltage range. Depending on the power supply, the inrush current protection may be activated to disable the power supply. Select the power supply and capacity carefully.

"E.SAF" or "E.P24" may appear when the start-up time of the 24 V power supply is too long (less than 1.5 V/s) in the 24 V external power supply operation.

"E.P24" may appear when the 24 V external power supply input voltage is low. Check the external power supply input. Do not touch the control circuit terminal block (circuit board) during the 24 V power supply operation (when conducted).

Otherwise you may get an electric shock or burn.

Connection of motor with encoder (vector control)

Encoder cable

When using an encoder cable (FR-JCBL, FR-V5CBL, etc.) dedicated to the conventional motor, the cables need to be treated as the terminal block of the FR-A8AP is an insertion type. Cut the crimp terminal of the encoder cable and strip its sheath to make its cable wires loose. Also, treat the shielding wires of the shielded twisted pair cable to ensure that they will not contact conductive areas. Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.

INSTALLATION AND WIRING 63

Connection of motor with encoder (vector control)

Instructions for encoder cable wiring Use shielded twisted pair cables (0.2 mm2 or larger) to connect the FR-A8AP. For the wiring to terminals PG and SD, use

several cables in parallel or use a thick cable, according to the wiring length. To protect the cables from noise, run them away from any source of noise (such as the main circuit and power supply voltage).

1 When differential line driver is set and a wiring length is 30 m or more.

The wiring length can be extended to 100 m by increasing the 5 V power supply (approximately to 5.5 V) while using six or more 0.2 mm2 gauge

cables in parallel or a 1.25 mm2 or larger gauge cable. The voltage applied must be within power supply specifications of encoder.

To reduce noise of the encoder cable, earth (ground) the encoder's shielded cable to the enclosure (as close as possible to the inverter) with a P-clip or U-clip made of metal.

When one encoder is shared between FR-A8AP and CNC (computerized numerical controller), its output signal should be connected as shown below. In this case, the wiring length between FR-A8AP and CNC should be as short as possible, within 5 m.

NOTE For the details of the optional encoder dedicated cable (FR-JCBL/FR-V7CBL), refer to page 62. The FR-V7CBL is provided with a P-clip for earthing (grounding) shielded cables.

1 The pin number differs according to the encoder used. The control works properly with or without the Z-phase being connected.

2 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1. 3 Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to page 64.) 4 For the complementary, set the terminating resistor selection switch to OFF position. (Refer to page 61.) 5 A separate power supply of 5 V / 12 V / 15 V / 24 V is necessary according to the encoder power specification.

When the encoder output is the differential line driver type, only 5 V can be input. Make the voltage of the external power supply the same as the encoder output voltage, and connect the external power supply between PG and SD.

6 For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8AP, refer to page 63.

2.10.1 Connection of the brake unit (FR-BU2) Connect the brake unit (FR-BU2) as shown below to improve the braking capability during deceleration. After wiring securely, set Pr.30 Regenerative function selection = "11 or 111" . Set Pr.0 Brake mode selection = "2" in the brake unit FR-BU2.

NOTE The stall prevention (overvoltage), oL, does not occur while Pr.30 Regenerative function selection = "11 or 111" . For the parameter details, refer to the FR-A800 Instruction Manual (Detailed).

1 When wiring, make sure to match the terminal symbol (P/+, N/-) at the inverter side and at the brake unit (FR-BU2) side. (Incorrect connection will damage the inverter and brake unit.)

2 For wiring to terminals P/+ and N/- of the FR-A842-08660(355K) or lower inverters, up to two cables can be connected. For wiring to the terminals of the FR-A842-09620(400K) or higher inverters, up to four cables can be connected. To use more cables, use a bus bar.

3 When the power supply is 400 V class, install a stepdown transformer. 4 The wiring distance between the inverter and brake unit (FR-BU2), and between the brake unit (FR-BU2) and

resistor unit (MT-BR5) must be within 5 m. Even when the wire is twisted, the cable length must be within 10 m. 5 The contact between TH1 and TH2 is open in the normal status and is closed at a fault. 6 The CN8 connector used with the MT-BU5 type brake unit is not used.

2.10.2 Connection of the high power factor converter (FR-HC2)

When connecting the high power factor converter (FR-HC2) to suppress power harmonics, perform wiring securely as shown below. Incorrect connection will damage the high power factor converter and the inverter. After making sure that the wiring is correct, set "rated motor voltage" in Pr.19 Rated motor voltage (under V/F control) or Pr.83 Regenerative function selection (under other that V/F control) and "2 or 102" in Pr.30 Regenerative function selection.

1 Remove jumpers installed in terminals R1/L11 and S1/L21 of the inverter, and connect the power supply for the control circuit to terminals R1/L11 and S1/L21.

2 The voltage phases of terminals R4/L14, S4/L24, and T4/L34 and the voltage phases of terminals R/L1, S/L2, and T/L3 must be matched. 3 Do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-). Connecting the opposite polarity of

terminals N/- and P/+ will damage the inverter. For the A802 series, installation of a fuse is not required.

4 Change the FR-HC2 parameter setting to Pr.10 RDY signal logic selection = "0" (positive logic). 5 Use Pr.178 to Pr.189 (input terminal function selection) to assign the terminals used for the X10 signal.

For RS-485 or any other communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the time of an instantaneous power failure.

6 Assign the IPF signal to an FR-HC2 terminal. (Refer to the Instruction Manual of FR-HC2.) 7 Always connect the FR-HC2 terminal RDY to the inverter terminal MRS (X10), and the FR-HC2 terminal SE to the inverter terminal SD. Not

connecting these terminals may damage the FR-HC2. 8 Always connect the R/L1, S/L2, and T/L3 terminals of FR-HC2 to the power supply. Operating the inverter without connecting them will

damage the FR-HC2. 9 Do not install an MCCB or MC between the reactor 1 terminals (R/L1, S/L2, T/L3) and the FR-HC2 terminals (R4/L14, S4/L24, T4/L34). It

will not operate properly. 10 Securely perform grounding (earthing) by using the grounding (earthing) terminal. 11 The number of connected peripheral devices differs according to the capacity. For the detail, refer to the FR-HC2 Instruction Manual.

NOTE The voltage phases of terminals R/L1, S/L2, and T/L3 and the voltage phases of terminals R4/L14, S4/L24, and T4/L34 must

be matched. The control logic (sink logic/source logic) of the high power factor converter and the inverter must be matched. (Refer to page

46.) When using a sine wave filter with FR-HC2, select MT-BSL-HC as a reactor for the sine wave filter. For the parameter details, refer to the FR-A800 Instruction Manual (Detailed).

2.10.3 Connection of the power regeneration converter (MT-RC)

When connecting the power regeneration converter (MT-RC), perform wiring securely as shown below. Incorrect connection will damage the power regeneration converter and the inverter. After making sure that the wiring is correct, set "1 or 101" in Pr.30 Regenerative function selection.

1 For wiring to terminals P/+ and N/- of the FR-A842-08660(355K) or lower inverters, up to two cables can be connected. For wiring to the terminals of the FR-A842-09620(400K) or higher inverters, up to four cables can be connected. To use more cables, use a bus bar.

NOTE When using the inverter with the MT-RC, install a magnetic contactor (MC) at

the input side of the inverter so that power is supplied to the inverter after 1 s or more has elapsed after powering ON the MT-RC. When power is supplied to the inverter prior to the MT-RC, the inverter and the MT-RC may be damaged or the MCCB may trip or be damaged.

When connecting the power coordination reactor and others, refer to Instruction Manual of the MT-RC for precautions.

Electro-magnetic interference (EMI) and leakage currents

3.1 Electro-magnetic interference (EMI) and leakage currents

3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following countermeasures. Select the earth leakage current breaker according to its rated sensitivity current, independently of the carrier frequency setting.

To-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other lines through the earthing (grounding) cable, etc. These leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily.

Countermeasures If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.

Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other

line, operation can be performed with the carrier frequency kept high (with low noise). To-earth (ground) leakage currents Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter reduces the

leakage current. Increasing the motor capacity increases the leakage current.

Line-to-line leakage currents Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external thermal relay unnecessarily.

Countermeasures Use Pr.9 Electronic thermal O/L relay. If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.

Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.

Installation and selection of the molded case circuit breaker Install a molded case circuit breaker (MCCB) on the power receiving side to protect the wiring at the inverter input side. Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output frequency and load. Especially for a completely electromagnetic MCCB, a slightly large capacity must be selected since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.) As an earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge suppression.

PRECAUTIONS FOR USE OF THE INVERTER 73

Electro-magnetic interference (EMI) and leakage currents

NOTE Install the earth leakage circuit breaker (ELB) on the input side of the converter unit.

In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250, IEC 61140 class 1 and other applicable standards)

When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even if the effective value is within the rating. In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to temperature rise.

The following models are standard breakers BV-C1, BC-V, NVB, NV-L, NV-G2N, NV-G3NA, NV-2F, earth leakage relay (except NV-ZHA), and NV with AA neutral wire open-phase protection. The other models are designed for harmonic and surge suppression: NV-C/NV-S/MN series, NV30-FA, NV50-FA, BV-C2, earth leakage alarm breaker (NF-Z), NV-ZHA, and NV-H.

For the leakage current of a 75 kW or higher motor, contact the motor manufacturer.

3.1.2 Precautions against inverter-generated EMI Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate electromagnetic noises. For prevention of malfunction of peripheral devices caused by electromagnetic noises EMI precautions should be taken to suppress noises. These techniques differ slightly depending on EMI paths.

Basic techniques - Do not run the power cables (I/O cables) and signal cables of the inverter or the converter unit in parallel with each other

and do not bundle them. - Use shielded twisted pair cables for the detector connecting and control signal cables and connect the sheathes of the

shielded cables to terminal SD. - Ground (Earth) the inverter or the converter unit, motor, etc. at one point.

Techniques to reduce electromagnetic noises that enter and cause a malfunction of the inverter or the converter unit (EMI countermeasures) When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many relays, for example) are installed near the inverter or the converter unit and it may malfunction due to electromagnetic noises, the following countermeasures must be taken: - Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises. - Install data line filters (page 76) to signal cables. - Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.

Techniques to reduce electromagnetic noises that are radiated by the inverter or converter unit to cause the peripheral devices to malfunction (EMI countermeasures) Noises generated from the inverter or the converter unit are largely classified into those radiated by the cables connected to the inverter or the converter unit and its main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

Noise propagation path Countermeasure

(a)(b)(c)

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or the converter unit, or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises. The following countermeasures must be taken: Install easily affected devices as far away as possible from the inverter or the converter unit. Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O cables.

Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other and do not bundle them.

Set the EMC filter ON/OFF connector of the converter unit to the ON position. (Refer to page 78.) Inserting a line noise filter into the output suppresses the radiated noise from the cables. Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce further effects.

(d)(e)(f)

When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables to cause malfunction of the devices and the following countermeasures must be taken: Install easily affected devices as far away as possible from the inverter or the converter unit. Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O cables.

Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other and do not bundle them.

Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce further effects.

(g)

When the power supplies of the peripheral devices are connected to the power supply of the inverter or the converter unit in the same line, its generated noises may flow back through the power supply cables to cause malfunction of the devices and the following countermeasures must be taken: Set the EMC filter ON/OFF connector of the converter unit to the ON position. (Refer to page 78.) Install the line noise filter to the power cables (output cables) of the inverter.

(h)

When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter or the converter unit, leakage currents may flow through the earthing (grounding) cable of the inverter or the converter unit to cause the device to malfunction. In that case, disconnecting the earthing (grounding) cable from the device may stop the malfunction of the device.

Electro-magnetic interference (EMI) and leakage currents

3.1.3 Converter unit (FR-CC2) built-in EMC filter The converter unit (FR-CC2) is equipped with a built-in EMC filter (capacitive filter). These filters are effective in reducing air-propagated noise on the input side of the converter unit. To enable the EMC filter, fit the EMC filter ON/OFF connector to the ON position. Both of two EMC filter ON/OFF connectors are initially set to the OFF position (disabled). To enable the EMC filter, fit the both EMC filter ON/OFF connectors to the ON position.

Before removing a front cover, check to make sure that the indication of the inverter operation panel is OFF, wait for at least

10 minutes after the power supply has been switched OFF, and check that there is no residual voltage using a tester or the like.

When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or forcibly pulling the connector with the tab fixed. When installing the connector, also engage the fixing tab securely. (If it is difficult to disconnect the connector, use a pair of needle-nose pliers, etc.)

NOTE Fit the connector to either ON or OFF position. Enabling (turning ON) the EMC filter increases leakage current. (Refer to page 73.)

WARNING While the inverter power is ON, do not open the front cover. Otherwise you may get an electric shock.

3.2 Power supply harmonics

3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path. Take the following countermeasure suppression techniques.

The differences between harmonics and noises

Countermeasures

NOTE The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by

the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the inverter. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

Item Harmonics Noise

Frequency Normally 40th to 50th degrees or less (3 kHz or less). High frequency (several 10 kHz to 1 GHz order).

Environment To-electric channel, power impedance. To-space, distance, wiring path, Quantitative understanding Theoretical calculation possible. Random occurrence, quantitative grasping difficult.

Generated amount Nearly proportional to the load capacity. Changes with the current variation ratio. (Gets larger as switching speed increases.)

Affected equipment immunity Specified by standards per equipment. Different depending on maker's equipment specifications. Countermeasure Provide a reactor. Increase distance.

The harmonic current generated from the inverter to the input side differs according to various conditions such as the wiring impedance, whether a reactor is used or not, and output frequency and output current on the load side. For the output frequency and output current, we understand that this should be calculated in the conditions under the rated load at the maximum operating frequency.

PRECAUTIONS FOR USE OF THE INVERTER 79

Power supply harmonics

3.2.2 Harmonic Suppression Guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products" and other models were covered by "the Harmonic Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage". However, the transistorized inverter has been excluded from the target products covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products" in January 2004 and "the Harmonic Suppression Guideline for Household Appliances and General-purpose Products" was repealed on September 6, 2004. All capacity and all models of general-purpose inverter used by specific consumers are now covered by "the Harmonic Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage" (hereinafter referred to as "the Specific Consumer Guidelines"). "Specific Consumer Guidelines"

This guideline sets forth the maximum harmonic currents outgoing from a high-voltage or especially high-voltage receiving consumer who will install, add or renew harmonic generating equipment. If any of the maximum values is exceeded, this guideline requires that consumer to take certain suppression measures.

No. Item Description

1 Reactor installation (FR-HAL)

The converter unit (FR-CC2) is equipped with the DC reactor on its DC side, and outgoing harmonic current can be suppressed. By installing an AC reactor (FR-HAL) on the AC side of the inverter, the outgoing harmonic current suppression performance can be improved.

2 high power factor converter (FR-HC2)

This converter trims the current waveform to be a sine waveform by switching the rectifier circuit (converter module) with transistors. Doing so suppresses the generated harmonic amount significantly. Connect it to the DC area of an inverter. Use the high power factor converter (FR-HC2) with the accessories that come as standard.

3 Installation of power factor improving capacitor

When used with a reactor connected in series, the power factor improving correction capacitor can absorb harmonic currents.

4 Transformer multi-phase operation

Use two transformers with a phase angle difference of 30 as in - and - combinations to provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.

5 Passive filter (AC filter)

A capacitor and a reactor are used together to reduce impedances at specific frequencies. Harmonic currents are expected to be absorbed greatly by using this technique.

6 Active filter (Active filter)

This filter detects the current in a circuit generating a harmonic current and generates a harmonic current equivalent to a difference between that current and a fundamental wave current to suppress the harmonic current at the detection point. Harmonic currents are expected to be absorbed greatly by using this technique.

PRECAUTIONS FOR USE OF THE INVERTER 81

Installation of a reactor

3.3 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor correction capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this, always install an optional AC reactor (FR-HAL).

Power-OFF and magnetic contactor (MC)

3

3.4 Power-OFF and magnetic contactor (MC)

Converter unit input side magnetic contactor (MC) On the converter unit input side, it is recommended to provide an MC for the following purposes: (Refer to page 16 for selection.) To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving

system (emergency stop, etc.). To prevent any accident due to an automatic restart at power restoration after an inverter stop made by a power failure. To separate the inverter from the power supply to ensure safe maintenance and inspection work. If using an MC for emergency stop during operation, select an MC regarding the converter unit input side current as JEM 1038-AC-3 class rated current.

NOTE Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about 1,000,000

times), frequent starts and stops of the magnetic contactor must be avoided. Turn ON/OFF the inverter start controlling terminals (STF, STR) to run/stop the inverter.

Inverter start/stop circuit example As shown below, always use the start signal (ON or OFF of STF(STR) signal) to make a start or stop.

1 When the power supply is 400 V class, install a stepdown transformer. 2 Connect the power supply terminals R1/L11, S1/L21 of the control circuit to the input side of the MC to hold an alarm signal when the inverter's

protective circuit is activated. At this time, remove jumpers across terminals R1/L11 and S1/L21. (Refer to page 51 for removal of the jumper.)

Handling of the magnetic contactor on the inverter's output side Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and such will activate. (The commercial power supply operation is not available with vector control dedicated motors.)

NOTE Do not open or close the contactor while the inverter is running (outputting).

PRECAUTIONS FOR USE OF THE INVERTER 83

Countermeasures against deterioration of the 400 V class motor insulation

3.5 Countermeasures against deterioration of the 400 V class motor insulation

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially in a 400 V class motor, the surge voltage may deteriorate the insulation. When the 400 V class motor is driven by the inverter, consider the following countermeasures:

Countermeasures It is recommended to take one of the following countermeasures:

Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length For the 400 V class motor, use an insulation-enhanced motor. Specifically, - Order a "400 V class inverter-driven insulation-enhanced motor". - For the dedicated motor such as the constant-torque motor and low-vibration motor, use an "inverter-driven dedicated

motor". - Set Pr.72 PWM frequency selection as indicated below according to the wiring length.

Suppressing the surge voltage on the inverter side - If the motor capacity is 280 kW or lower, connect the sine wave filter (MT-BSL/BSC) to the output side.

NOTE When using the optional sine wave filter (MT-BSL/BSC), set Pr.72="25" (2.5 kHz). For the details of the sine wave filter (MT-BSL/BSC), refer to the Instruction Manual of each option. A sine wave filter (MT-BSL/BSC) can be used under V/F control. Do not use the filters under different control methods.

Wiring length 100 m or shorter Longer than 100 m

Pr.72 PWM frequency selection 6 (6 kHz) or lower 4 (4 kHz) or lower

84 PRECAUTIONS FOR USE OF THE INVERTER

Checklist before starting operation

3.6 Checklist before starting operation The FR-A800 series inverter and FR-CC2 converter unit are highly reliable products, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the products. Before starting operation, always recheck the following points.

Checkpoint Countermeasure Refer to page

Check by user

Crimp terminals are insulated. Use crimp terminals with insulation sleeves to wire the power supply and the motor. -

The wiring between the power supply (R/L1, S/L2, T/L3) and the motor (U, V, W) is correct.

Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring. 37

No wire offcuts are left from the time of wiring.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter and the converter unit clean. When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter and the converter unit.

-

The main circuit cable gauge is correctly selected.

Use an appropriate cable gauge to suppress the voltage drop to 2% or less. If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to decrease especially during the output of a low frequency.

38

The total wiring length is within the specified length.

Keep the total wiring length is within the specified length. In long distance wiring, charging currents due to stray capacitance in the wiring may degrade the fast-response current limit operation or cause the equipment on the inverter's output side to malfunction. Pay attention to the total wiring length.

38

Countermeasures are taken against EMI.

The input/output (main circuit) of the inverter and the converter unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter and the converter unit. In such case, activate the EMC filter (turn ON the EMC filter ON/OFF connector) to minimize interference.

78

On the inverter's output side, there is no power factor correction capacitor, surge suppressor, or radio noise filter installed.

Doing so will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is connected, immediately remove it.

-

When performing an inspection or rewiring on the product that has been energized, the operator has waited long enough after shutting off the power supply.

For a short time after the power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous. Before performing an inspection or rewiring, wait 10 minutes or longer after the power supply turns OFF, then confirm that the voltage across the main circuit terminals P/+ and N/- of the inverter is low enough using a tester, etc.

-

The inverter's output side has no short circuit or ground fault occurring.

A short circuit or earth (ground) fault on the inverter's output side may damage the inverter module.

Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter module.

Fully check the to-earth (ground) insulation and phase-to-phase insulation of the inverter's output side before power-ON. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance, etc.

-

The circuit is not configured to use the converter unit's input-side magnetic contactor to start/stop the inverter frequently.

Since repeated inrush currents at power ON will shorten the life of the inverter and the converter unit, frequent starts and stops of the magnetic contactor must be avoided. Turn ON/OFF the inverter's start signals (STF, STR) to run/stop the inverter.

83

The voltage applied to the I/O signal circuits of the inverter and the converter unit is within the specifications.

Application of a voltage higher than the permissible voltage to the I/O signal circuits of the inverter and the converter unit or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short circuit terminals 10E and 5.

41

PRECAUTIONS FOR USE OF THE INVERTER 85

Checklist before starting operation

The converter unit and the inverter are correctly connected.

Make sure that terminal P/+ of the converter unit and terminal P/+ of the inverter, and terminal N/- of the converter unit and terminal N- of the inverter are correctly connected. Connecting the opposite polarity of terminals N/- and P/+ will damage the inverter. Also, do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-).

Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of the converter unit and terminal SD (terminal PC for source logic) of the inverter. Not connecting these terminals may damage the converter unit.

35

When using the electronic bypass operation, electrical and mechanical interlocks are provided between the electronic bypass contactors MC1 and MC2.

When using a switching circuit as shown below, chattering due to mis- configured sequence or arc generated at switching may allow undesirable current to flow in and damage the inverter. Mis-wiring may also damage the inverter. (The commercial power supply operation is not available with vector control dedicated motors.)

If switching to the commercial power supply operation while a failure such as an output short circuit has occurred between the magnetic contactor MC2 and the motor, the damage may further spread. If a failure has occurred between the MC2 and the motor, a protection circuit such as using the OH signal input must be provided.

-

A countermeasure is provided for power restoration after a power failure.

If the machine must not be restarted when power is restored after a power failure, provide an MC in the converter unit's input side and also make up a sequence which will not switch ON the start signal. If the start signal (start switch) remains ON after a power failure, the inverter will automatically restart as soon as the power is restored.

-

When using vector control, the encoder is properly installed.

The encoder must be directly connected to a motor shaft without any backlash. (Real sensorless vector control do not require an encoder.) 60

A magnetic contactor (MC) is installed on the converter unit's input side.

On the converter unit's input side, connect an MC for the following purposes: To disconnect the inverter and the converter unit from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).

To prevent any accident due to an automatic restart at power restoration after an inverter stop made by a power failure.

To separate the inverter and the converter unit from the power supply to ensure safe maintenance and inspection work.

If using an MC for emergency stop during operation, select an MC regarding the converter unit input side current as JEM 1038-AC-3 class rated current.

83

The magnetic contactor on the inverter's output side is properly handled.

Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. 83

An EMI countermeasure is provided for the frequency setting signals.

If electromagnetic noise generated from the inverter and the converter unit causes frequency setting signal to fluctuate and the motor rotation speed to be unstable when changing the motor speed with analog signals, the following countermeasures are effective: Do not run the signal cables and power cables (inverter and converter unit I/ O cables) in parallel with each other and do not bundle them.

Run signal cables as far away as possible from power cables (inverter and converter I/O cables).

Use shielded cables. Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

1 Recommended common mode choke: FT-3KM F series FINEMET common mode choke cores manufactured by Hitachi Metals, Ltd. FINEMET is a registered trademark of Hitachi Metals, Ltd.

A countermeasure is provided for an overload operation.

When performing frequent starts/stops by the inverter, rise/fall in the temperature of the transistor element of the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting current, etc. Reducing current may extend the service life but may also cause torque shortage, which leads to a start failure. Adding a margin to the current can eliminate such a condition. For an induction motor, use the inverter and the converter unit of a higher capacity (up to two ranks).

-

The specifications and rating match the system requirements.

Make sure that the specifications and rating match the system requirements. -

Countermeasures are taken against electrical corrosion on the motor bearing.

When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or specific inverter settings (high carrier frequency and EMC filter ON). Contact your sales representative to take appropriate countermeasures for the motor. The following shows examples of countermeasures for the inverter. Decrease the carrier frequency. Turn OFF the EMC filter. Provide a common mode choke on the output side of the inverter.1 (This is effective regardless of the EMC filter ON/OFF connector setting.)

Failsafe system which uses the inverter

3.7 Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function is activated and outputs a fault signal. However, a fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.

Interlock method which uses the inverter status output signals By combining the inverter output signals to provide an interlock as shown below, an inverter failure can be detected.

(a) Checking by the output of the inverter fault signal When the inverter's protective function is activated and the inverter trips, the Fault signal is output. (The ALM signal is assigned to terminal A1B1C1 in the initial setting). With this signal, check that the inverter operates properly. In addition, negative logic can be set. (ON when the inverter is normal, OFF when the fault occurs.)

(b) Checking the inverter operating status by the inverter operation ready completion signal The Operation ready (RY) signal is output when the inverter power is ON and the inverter becomes operative. Check if the RY signal is output after powering ON the inverter.

(c) Checking the inverter operating status by the start signal input to the inverter and inverter running signal The Inverter running (RUN) signal is output when the inverter is running. (The RUN signal is assigned to terminal RUN in the initial setting.) Check if Y12 signal is being output while inputting a start signal to the inverter. (The STF signal is a forward rotation signal, and the STR signal is a reverse rotation signal.) Even after the start signal is turned OFF, the RUN signal is kept output until the inverter makes the motor to decelerate and to stop. For the logic check, configure a sequence considering the inverter's deceleration time.

NOTE Changing the terminal assignment using Pr.190 and Pr.196 (output terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal. For the details of the parameters and signals, refer to the FR-A800 Instruction Manual (Detailed).

Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of the inverter itself. For example, if an inverter CPU fails in a system interlocked with the inverter's fault, start, and RUN signals, no fault signal will be output and the RUN signal will be kept ON because the inverter CPU is down. Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the backup system such as performing a check as below according to the level of importance of the system.

(a) Start signal and actual operation check Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to the inverter and detected speed of the speed detector or detected current of the current detector. Note that the current is flowing through the motor while the motor coasts to stop, even after the inverter's start signal is turned OFF. For the logic check, configure a sequence considering the inverter's deceleration time. In addition, it is recommended to check the three-phase current when using the current detector.

(b) Command speed and actual operation check Check for a gap between the actual speed and commanded speed by comparing the inverter's speed command and the speed detected by the speed detector.

(d) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal The Output current detection (Y12) signal is output when the inverter operates and current flows into the motor. Check if the Y12 signal is being output while inputting a start signal to the inverter. (The STF signal is a forward rotation signal, and the STR signal is a reverse rotation signal.) The Y12 signal is initially set to be output at 150% inverter rated current. Adjust the level to around 20% using no load current of the motor as reference with Pr.150 Output current detection level. Like the Inverter running (RUN) signal, even after the start signal is turned OFF, the Y12 signal is kept output until the inverter stops the output to a decelerating motor. For the logic check, configure a sequence considering the inverter's deceleration time.

When using various signals, assign the functions to Pr.190 and Pr.196 (output terminal function selection) referring to the table on the left.

Inverter fault and indications

4.1 Inverter fault and indications When a fault occurs in the inverter, a protective function is automatically activated to shut off the inverter output and show

an indication on the operation panel of the inverter. When any fault occurs, take an appropriate corrective action, then reset the inverter, and resume the operation. Restarting

the operation without a reset may break or damage the inverter. When a protective function is activated, note the following points.

Inverter fault or alarm indications are categorized as below.

NOTE For the details of fault displays and other malfunctions, refer to the FR-A800 Instruction Manual (Detailed). The past eight faults can be displayed on the operation panel. (Fault history) (For operation, refer to page 93.)

4.2 Reset method for the protective functions Reset the inverter by performing any of the following operations. Note that the accumulated heat value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter. The inverter recovers about 1 s after the reset is released.

NOTE OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting an inverter fault with the start

signal ON restarts the motor suddenly.

5.1.4 Checking the inverter and converter semiconductor devices

Preparation Disconnect the external power supply cables (R/L1, S/L2, T/L3) and motor cables (U, V, W). (The inverter and the converter

unit (FR-CC2) can be measured with those cables connected.) Prepare a continuity tester. (For the resistance measurement, use the 100 range.)

Checking method Change the polarity of the tester alternately at a semiconductor device (transistor) on an electrical path between two terminals among the inverter main circuit terminals R/L1, S/L2, T/L3, U, V, W, P/+, and N/- to check the electric continuity.

NOTE Before measurement, check that the smoothing capacitor is discharged. At the time of electric discontinuity, the measured value is almost . When there is an instantaneous electric continuity, due to

the smoothing capacitor, the tester may not indicate . At the time of electric continuity, the measured value is several to several tens of . When all measured values are almost the same (although values may not be constant depending on the tester type), it shows that there are no electrical paths with problems.

5.1.5 Cleaning Always run the inverter in a clean status. When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol.

NOTE Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off. The display, etc. of the operation panel and parameter unit are vulnerable to detergent and alcohol. Therefore, avoid using

them for cleaning.

5.1.6 Replacement of parts The inverter consists of many electronic parts such as semiconductor devices. The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically. The standard replacement interval of the inverter parts is as follows.

1 Estimated lifespan for when the yearly average surrounding air temperature is 40C. (without corrosive gas, flammable gas, oil mist, dust and dirt etc.)

2 Output current (80% of the inverter rating)

NOTE For parts replacement, contact the nearest Mitsubishi FA center.

Inverter parts life display The inverter diagnoses the control circuit capacitor and the cooling fan by itself, and estimates their lives. The self-diagnostic warning is output when the life span of each part is near its end. It gives an indication of replacement time. The life warning output can be used as a guideline for life judgment.

NOTE Refer to the FR-A800 Instruction Manual (Detailed) to perform the life check of the inverter parts.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION 101

Inspection item

Replacement procedure of the cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the cooling fan must be replaced immediately.

Removal 1) Remove the fan cover fixing screws, and remove the fan cover. 2) Disconnect the fan connector and remove the fan block. 3) Remove the fan fixing screws, and remove the fan.

1 The number of cooling fans differs according to the inverter capacity.

Reinstallation 1)Before installing the new fan, check the orientation of the fan to be sure that the "AIR FLOW" arrow printed on the side of the fan points upward.

2) For reconnection of the fan, refer to the above figure. The tightening torque of the fan fixing screws is 0.73 Nm.

NOTE Installing the fan in the opposite direction of air flow can cause the inverter life to be shorter. Prevent the cable from being caught when installing a fan. Switch the power OFF before replacing fans. Since the inverter circuits are charged with voltage even after power OFF,

replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.

Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the DC section of the main circuit, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Adverse effects from ripple currents deteriorate capacitors. Replacement intervals of capacitors vary greatly with surrounding temperatures and operating conditions. Replace them roughly every 10 years when used in normal air-conditioned environments. Inspecting the product visually: Case: Check that the sides and bottom of the capacitor have not ruptured. Rubber seal: Check for any noticeable bulging or severe cracks. Check for external cracks, discoloration, leakage, etc. It is assumed that the capacitor has reached the end of its life when

its capacity has dropped below 80% of its rated capacity.

NOTE The inverter diagnoses the control circuit capacitor by itself and can judge its life. (Refer to the FR-A800 Instruction Manual

(Detailed))

Relay output terminals The contacts of relays deteriorate over time. To prevent faults from occurring, relays must be replaced when they have

reached the maximum of switching operations (switching life). The control terminal block must be replaced in case of failure of either relay connected to the relay output terminals A1, B1,

and C1, or A2, B2, and C2. (After replacing the control terminal block, connect the jumper connector to the correct position in accordance with the control logic of input signals. (Refer to page 46.))

Main circuit fuse A fuse is used inside the inverter. Replacement intervals of fuses vary with surrounding temperatures and operating conditions. Replace them roughly every 10 years when used in normal air-conditioned environments.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION 103

Inspection item

5.1.7 Removal and reinstallation of the control circuit terminal block

The FR-A800 series inverter has a removable control circuit terminal block, which can be replaced with a new one or a control terminal option.

Removal and reinstallation 1) Loosen the two mounting screws at the both side of the control circuit terminal block. (These screws cannot be removed.)

Slide down the control circuit terminal block to remove it.

2) Be careful not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it with the mounting screws.

NOTE Before starting the replacement, power OFF the inverter, wait for at least 10 minutes, and then check that the charge lamp is

OFF to ensure safety.

Removal and reinstallation precautions Precautions to be taken when removing or reinstalling the control circuit terminal block are shown below. Observe the following precautions and handle the inverter properly to avoid malfunctions or failures. To remove or reinstall the control circuit terminal block, keep it upright so that it is parallel with the inverter. To install the control circuit terminal block, slide it upward so that the tongues on the inverter slot into the grooves on the terminal block. Check that the terminal block is parallel to the inverter and the pins on the inverter control circuit connector are not bent.

After checking proper connection, fix the terminal block in place with two screws.

NOTE Do not tilt the terminal block while tightening the screws or removing it from the inverter. (Otherwise, stress applied to the

control circuit terminal block or the control circuit connector may damage the pins.) After replacing the control terminal block, connect the jumper connector to the correct position in accordance with the control

logic of input signals. (Refer to page 46.)

5.2 Measurement of main circuit voltages, currents and powers

Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments given on the next page.

NOTE When installing meters etc. on the inverter output side

When the wiring length between the inverter and the motor is large, the meters and CTs may generate heat due to line-to-line leakage current. Therefore, choose equipment which has enough capacity for the current rating. To measure and display the output voltage and output current of the inverter, it is recommended that the terminal AM and FM/ CA output functions of the inverter are used.

106 PRECAUTIONS FOR MAINTENANCE AND INSPECTION

Measurement of main circuit voltages, currents and powers

5

1 Use an FFT to measure the output voltage accurately. A tester or general measuring instrument cannot measure accurately. 2 When the carrier frequency exceeds 5 kHz, do not use this instrument since using it may increase eddy current losses produced in metal parts

inside the instrument, leading to burnout. In this case, use an approximate-effective value type. 3 When the setting of Pr.195 ABC1 terminal function selection is the positive logic 4 A digital power meter (designed for inverter) can also be used to measure.

5.2.1 Measurement of powers Use a digital power meter (for inverter) for the input side of the converter unit (FR-CC2) and the output side of the inverter.

5.2.2 Measurement of voltages Converter unit (FR-CC2) input side Use digital power meters (for inverters) for the input side voltage.

Inverter output side When using a measuring instrument, use a digital power meter for inverters as the inverter outputs PWM-controlled square wave voltage. The value displayed on the operation panel is the inverter-controlled voltage itself. Hence, that value is accurate and it is recommended to monitor values using the operation panel.

5.2.3 Measurement of currents Use a digital power meter (for inverter) for the input side of the converter unit (FR-CC2) and the output side of the inverter. Since the converter unit input current tends to be unbalanced, measurement of three phases is recommended. The correct value cannot be obtained by measuring only one or two phases. On the other hand, the unbalanced ratio of each phase of the output current should be within 10%. The inverter output current can be monitored on the operation panel. The value displayed on the operation panel is accurate even if the output frequency varies. Hence, it is recommended to monitor values on the operation panel.

5.2.4 Example of measuring converter unit (FR-CC2) input power factor

Calculate using effective power and apparent power. A power-factor meter cannot indicate an exact value.

5.2.5 Measurement of converter output voltage (across terminals P and N)

The output voltage of the converter is output across terminals P and N, and can be measured with a voltmeter such as a digital multimeter. Although the voltage varies according to the power supply voltage, approximately 540 to 600 V is output when no load is connected and voltage decreases during driving load operation. When energy is regenerated from the motor during deceleration, for example, the converter output voltage rises to nearly 800 to 900 V maximum.

Total power factor of the converter unit = Effective power Apparent power

= Three-phase input power found by the 3-wattmeter method

PRECAUTIONS FOR MAINTENANCE AND INSPECTION 107

Measurement of main circuit voltages, currents and powers

5.2.6 Measurement of inverter output frequency In the initial setting of the FM-type inverter, a pulse train proportional to the output frequency is output across the pulse train output terminals FM and SD of the inverter. This pulse train output can be counted by a frequency counter, or a digital multimeter can be used to read the mean value of the pulse train output voltage. When a meter is used to measure the output frequency, approximately 5 VDC is indicated at the maximum frequency. For detailed specifications of the pulse train output terminal FM, refer to the FR-A800 Instruction Manual (Detailed). In the initial setting of the CA-type inverter, a pulse train proportional to the output frequency is output across the analog current output terminals CA and 5 of the inverter. Measure the current using a digital multimeter. For detailed specifications of the analog current output terminal CA, refer to the FR-A800 Instruction Manual (Detailed).

5.2.7 Insulation resistance test using megger For the inverter and the converter unit (FR-CC2), conduct the insulation resistance test on the main circuit only as shown

below and do not perform the test on the control circuit. (Use a 500 VDC megger.)

NOTE Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the inverter

and the converter unit so that the test voltage is not applied to the inverter and the converter unit. For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.

5.2.8 Pressure test Do not conduct a pressure test. Deterioration may occur.

Appendix 2 Instructions for compliance with the EU Directives

The EU Directives are issued to standardize different national regulations of the EU Member States and to facilitate free movement of the equipment, whose safety is ensured, in the EU territory. Since 1996, compliance with the EMC Directive that is one of the EU Directives has been legally required. Since 1997, compliance with the Low Voltage Directive, another EU Directive, has been also legally required. When a manufacturer confirms its equipment to be compliant with the EMC Directive and the Low Voltage Directive, the manufacturer must declare the conformity and affix the CE marking. The authorized representative in the EU

The authorized representative in the EU is shown below. Company name: Mitsubishi Electric Europe B.V. Address: Mitsubishi-Electric-Platz 1, 40882 Ratingen, Germany

EMC Directive We declare that this inverter conforms with the EMC Directive and affix the CE marking on the inverter. EMC Directive 2014/30/EU Standard(s): EN 61800-3:2004+A1:2012 (Second environment / PDS Category "C3") This inverter is not intended to be used on a low-voltage public network which supplies domestic premises. When using the

inverter in a residential area, take appropriate measures and ensure the conformity of the inverter used in the residential area.

The installer shall provide a guide for installation and use, including recommended mitigation devices.

Note: First environment Environment including buildings/facilities which are directly connected to a low voltage main supply which also supplies residential buildings. Directly connected means that there is no intermediate transformer between these buildings. Second environment Environment including all buildings/facilities which are not directly connected to a low voltage main supply which also supplies residential buildings.

Note Set the EMC filter valid and install the inverter and perform wiring according to the following instructions. The FR-CC2 converter unit used with this inverter is equipped with a built-in EMC filter (Class C3). Enable the EMC

filter. (For details, refer to page 78.) Connect the inverter and the converter unit to an earthed power supply. Install a motor and a control cable written in the EMC Installation Manual (BCN-A21041-204) and Technical News (MF-

S-113) according to the instruction. To make full use of the built-in EMC filter, motor cable lengths should not exceed 20 m. Confirm that the inverter and the converter unit conform with the EMC Directive as the industrial drives application for

final installation.

APPENDIX 117

Low Voltage Directive We have self-confirmed our inverters as products compliant to the Low Voltage Directive and affix the CE marking on the inverters. Low Voltage Directive: 2014/35/EU Conforming standard: EN 61800-5-1:2007

Outline of instructions Do not use an earth leakage current breaker as an electric shock protector without connecting the equipment to the

earth. Connect the equipment to the earth (ground) securely. Wire the earth terminal independently. (Do not connect two or more cables to one terminal.) Use the cable sizes on page 38 under the following conditions.

Surrounding air temperature 40C maximum If conditions are different from above, select appropriate wire according to EN 60204-1 or IEC 60364-5-52.

Use a tinned (plating should not include zinc) crimp terminal to connect the earth (ground) cable. When tightening the screw, be careful not to damage the threads. For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated on page 38.

Use the molded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard. DC current may flow from the inverter to a protective earth (ground) conductor. When using a residual current device

(RDC) or residual current monitor (RDM), connect a type B RCD or RCM to the power supply side. Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the

power supply), overvoltage category III (usable with the earthed-neutral system power supply, 400 V class only) and pollution degree 2 or lower specified in IEC 60664. To use the inverter under the conditions of pollution degree 2, install it in the enclosure of IP2X or higher. To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.

On the input and output of the inverter and the converter unit, use cables of the type and size set forth in EN 60204-1 or IEC 60364-5-52

The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2, C2) should be 30 VDC, 0.3 A. (Relay output has basic isolation from the internal circuit of the inverter and the converter unit.)

Control circuit terminals on page 27 are safely isolated from the main circuit. Environment (For the detail, refer to page 20.)

1 For the installation in an altitude above 1000 m, derate the rated current 3% per 500 m.

Branch circuit protection Class T, Class J, Class CC, or Class L fuses must be provided. (Use a product which conforms to the EN or IEC Standard.)

Motor overload protection When using the electronic thermal relay function as motor overload protection, set the rated motor current in Pr.9 Electronic thermal O/L relay.

NOTE The internal accumulated heat value of the electronic thermal relay function is reset by inverter power reset and reset signal

input. Avoid unnecessary reset and power-OFF. Install an external thermal relay (OCR) between the inverter and motors to operate several motors, a multi-pole motor or a

dedicated motor with one inverter. Note that the current indicated on the motor rating plate is affected by the line-to-line leakage current (Refer to page 72) when selecting the setting for an external thermal relay.

The cooling effect of the motor drops during low-speed operation. Use a thermal protector or a motor with built-in thermistor. When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics

of the electronic thermal relay function will be deteriorated. In such case, use an external thermal relay. A dedicated motor cannot be protected by an electronic thermal O/L relay. Use an external thermal relay. Motor over temperature sensing is not provided by the drive. Electronic thermal memory retention function is not provided by the drive.

Operation characteristics of electronic thermal relay function

This function detects the overload of the motor and trips the inverter by stopping the operation of the transistor at the inverter output side. (The operation characteristic is shown on the left.) Mitsubishi Electric constant-torque motor (1) Set one of "1", "13" to "16" in Pr.71. (This setting will

enable the 100% constant-torque characteristic in the low-speed range.)

(2) Set the rated current of the motor in Pr.9.

1 When a value 50% of the inverter rated output current (current value) is set in Pr.9

2 The % value denotes the percentage to the inverter rated current. It is not the percentage to the rated motor current.

3 When you set the electronic thermal relay function dedicated to the Mitsubishi Electric constant-torque motor, this characteristic curve applies to operation at 6 Hz or higher.

4 Transistor protection is activated depending on the temperature of the heat sink. The protection may be activated even with less than 150% depending on the operating conditions.
