not run the converter with the front cover removed. Otherwise you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock. Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. Accidentally touching the charged converter circuits will result in electric shock. Before wiring or inspection, the power lamp must be switched
OFF. Any person who is involved in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous. Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work. The converter unit must be installed before wiring. Otherwise you
may get an electric shock or be injured. Setting dial and key operations must be performed with dry
hands to prevent an electric shock. Otherwise you may get an electric shock. Do not subject the cables to scratches, excessive stress, heavy
loads or pinching. Otherwise you may get an electric shock. Do not change the cooling fan while power is ON. It is dangerous
to change the cooling fan while power is ON. Do not touch the printed circuit board or handle the cables with
wet hands. Otherwise you may get an electric shock.
Warning
Caution
Caution
Caution The converter unit must be installed on a nonflammable wall
without holes (so that nobody touches the converter unit heatsink on the rear side, etc.). Mounting it to or near flammable material may cause a fire. If the converter unit has become faulty, the converter power must
be switched OFF. A continuous flow of large current may cause a fire. Be sure to perform daily and periodic inspections as specified in
the Instruction Manual. If a product is used without any inspection, a burst, breakage, or a fire may occur.
Caution The voltage applied to each terminal must be the ones specified
in the Instruction Manual. Otherwise a burst, damage, etc. may occur. The cables must be connected to the correct terminals.
Otherwise a burst, damage, etc. may occur. The polarity (+ and -) must be correct. Otherwise a burst,
damage, etc. may occur. While power is ON or for some time after power OFF, do not
touch the converter unit as it will be extremely hot. Touching these devices may cause a burn.
Caution Transportation and mounting Any person who is opening a package using a sharp object, such
as a knife and cutter, must wear gloves to prevent injuries caused by the edge of the sharp object. The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries. Do not stand or rest heavy objects on the product. Do not stack the boxes containing converters higher than the
number recommended. When carrying the converter, do not hold it by the front cover or
setting dial; it may fall off or fail. During installation, caution must be taken not to drop the
converter unit as doing so may cause injuries. The product must be installed on the surface that withstands the
weight of the converter unit. Do not install the product on a hot surface. The mounting orientation of the converter unit must be correct. The converter unit must be installed on a strong surface securely
with screws so that it will not drop. Do not install or operate the converter unit if it is damaged or has
parts missing. Foreign conductive objects must be prevented from entering the
converter unit. That includes screws and metal fragments or other flammable substance such as oil. As the converter unit is a precision instrument, do not drop or
subject it to impact. The surrounding air temperature must be -10 to +50C
(nonfreezing). (The temperature range depends on the inverter rating. Refer to page 17.) Otherwise the converter unit may be damaged. The ambient humidity must be 95%RH or less (non-condensing).
Otherwise the converter unit may be damaged. (For the details, refer to page 17.)
Safety instructions 1
DoS: A denial-of-service (DoS) attack disrupts services by overloading systems or exploiting vulnerabilities, resulting in a denial-of-service (DoS) state.
Caution Transportation and mounting The storage temperature (applicable for a short time, e.g. during
transit) must be between -20 and +65C. Otherwise the converter unit may be damaged. The converter unit must be used indoors (without corrosive gas,
flammable gas, oil mist, dust and dirt etc.) Otherwise the converter unit may be damaged. The converter unit must be used at an altitude of 2500 m or less
above sea level, with 2.9 m/s2 or less vibration at 10 to 55 Hz (directions of X, Y, Z axes). Otherwise the converter unit may be damaged. (For the details, refer to page 17.) If halogen-based materials (fluorine, chlorine, bromine, iodine,
etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before packing a product.
Test run Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to make unexpected motions.
Warning Usage Everyone must stay away from the equipment when the retry
function is set as it will restart suddenly after a trip. Since pressing a STOP/RESET key of the operation panel may
not stop output depending on the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided. OFF status of the start signal must be confirmed before resetting
an inverter fault. Resetting an converter unit fault with the start signal ON restarts the motor suddenly. Do not modify the equipment. Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
Caution Usage Do not use a magnetic contactor on the input side for frequent
starting/stopping of the inverter. Otherwise the life of the inverter and the converter unit decreases. The effect of electromagnetic interference must be reduced by
using a noise filter or by other means. Otherwise nearby electronic equipment may be affected. Appropriate measures must be taken to suppress harmonics.
Otherwise power supply harmonics from the inverter or the converter unit may heat/damage the power factor correction capacitor and generator. When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting operations. because all parameters return to their initial values. Before running a converter unit which had been stored for a long
period, inspection and test operation must be performed. Static electricity in your body must be discharged before you
touch the product. To maintain the security (confidentiality, integrity, and availability)
of the Converter unit, drive unit and the system against unauthorized access, DoS attacks, computer viruses, andother cyberattacks from external devices via network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions. We shall have no responsibility or liability for any problems involving Converter unit, drive unit trouble and system trouble by DoS attacks, unauthorized access, computer viruses, and other cyberattacks.
Emergency stop A safety backup such as an emergency brake must be provided
to prevent hazardous conditions to the machine and equipment in case of converter unit failure. When the breaker on the converter unit's input side trips, check
for the wiring fault (short circuit), damage to internal parts of the converter unit, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker. When a protective function is activated, take an appropriate
corrective action, then reset the converter unit (inverter), and resume the operation.
Maintenance, inspection and parts replacement Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter. It will cause a failure. Disposal The converter must be treated as industrial waste.

NOTE To prevent an electric shock, always earth (ground) the converter unit, the inverter, and the motor. 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. Refer to page 45 for countermeasures.
For details of options and peripheral devices, refer to the respective Instruction Manual. A PM motor cannot be driven by the commercial power supply. A PM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the
motor is running even after the inverter power is turned OFF. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is stopped.
Symbol Name Overview Refer to page
(a) Inverter (FR-A862/FR-F862) 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.
17 25
(b) Converter unit (FR-CC2)
(c) Three-phase AC power supply Must be within the permissible power supply specifications of the converter unit. 142
(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. 14
(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.
49
(f) AC reactor
Install this to suppress harmonics and to improve the power factor. An AC reactor is required when installing the inverter near a large power supply system (1000 kVA or more). The inverter or the converter unit may be damaged if you do not use a reactor. Select a reactor according to the applicable motor capacity.
48
(g) Noise filter Suppresses the noise radiated from the power supply side of the converter unit. 45
(h) Noise filter Install this to reduce the electromagnetic noise generated from the inverter or the converter unit. The noise filter is effective in the range from about 0.5 MHz to 5 MHz.

Peripheral devices
2.1.2 Peripheral devices Selecting the converter unit (FR-CC2) Select the capacity of the FR-CC2 converter unit according to the connected motor capacity. FR-A800 series
FR-F800 series
The applicable motor capacity indicated is the maximum capacity applicable for use of the 4-pole standard motor.
Selecting the breaker/magnetic contactor Check the model of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected according to the capacity. Refer to the table below to prepare appropriate peripheral devices.
NOTE When the converter unit capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to
the converter unit model, and select cables and reactors according to the motor output. When the breaker on the converter unit's input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter or the converter unit, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.

2.3 Installation of the converter unit and enclosure design
When designing or manufacturing an enclosure to contain the converter unit, 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. A converter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the converter unit in the ambient environment that completely satisfies the equipment specifications.
2.3.1 Converter unit installation environment The following table lists the standard specifications of the converter unit installation environment. Using the converter unit 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 converter unit
Temperature applicable for a short time, e.g. in transit. For the installation in an altitude above 1000 m (up to 2500 m), derate the rated current 3% per 500 m. The surrounding air temperature is a temperature measured at a measurement position in an enclosure.
The ambient temperature is a temperature outside an enclosure. For the details of the multiple rating of the inverter, refer to the Instruction Manual (Detailed) of the inverter.
Temperature The permissible surrounding air temperature of the converter unit is between -10C and +50C. (The temperature range depends on the inverter rating. Refer to the table above.) Always operate the converter unit 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 converter unit within the specified range. (a) Measures against high temperature Use a forced ventilation system or similar cooling system. (Refer to page 20.) 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 converter unit. (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 converter unit within the ambient air humidity of usually 45 to 95%. 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 JEM1103 "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 converter unit.
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 20.) 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 converter unit 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 above-mentioned measures.
Explosive, flammable gases As the converter unit 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 converter unit at an altitude of within 1000 m. For use at an altitude above 1000 m (up to 2500 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 converter unit is up to 2.9m/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.
Countermeasure 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.

2.3.2 Cooling system types for converter unit enclosure
From the enclosure that contains the converter unit, the heat of the converter unit 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 converter unit. 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 heatsink (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 cooling
Natural ventilation (enclosed, open type)
This system is low in cost and generally used, but the enclosure size increases as the converter unit 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 converter unit capacity.
Forced cooling
Heatsink cooling This system has restrictions on the heatsink 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.
Heat pipe This is a totally enclosed for enclosure downsizing.

2.3.3 Installation of the converter unit Installation of the converter unit
Install the converter unit on a strong surface securely with screws. Leave enough clearances and take cooling measures. Avoid places where the converter unit is subjected to direct sunlight, high temperature and high humidity. Install the converter unit on a nonflammable wall surface. When encasing multiple converter units in an enclosure, install them in parallel as a cooling measure. For heat dissipation and maintenance, keep clearance between the converter unit and the other devices or enclosure
surface. The clearance below the converter unit is required as a wiring space, and the clearance above the converter unit is required as a heat dissipation space.
For replacing the cooling fan, 30 cm or more of space is necessary in front of the converter unit. Refer to page 137 for fan replacement.
Installation orientation of the converter unit Install the converter unit on a wall as specified. Do not mount it horizontally or in any other way.
Above the converter unit Heat is blown up from inside the converter unit by the small fan built in the unit. Any equipment placed above the converter unit should be heat resistant.

Encasing multiple inverters and converter units
Arrangement of the ventilation fan and the converter unit
When multiple inverters and converter units are placed in the same enclosure, generally arrange them horizontally as shown in the figure on the right. Do not place multiple converter units or the converter unit and the inverter vertically. The exhaust air temperature of 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 converter unit 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 converter unit to cool air.)

2.5.4 Earthing (grounding) precautions Always earth (ground) 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 converter unit's high frequency components from entering the malfunction prevention type earthing (grounding): Whenever possible, use the independent earthing (grounding) for the converter unit.
If independent earthing (grounding) (I) is not available, use (II) common earthing (grounding) in the figure below where the converter unit 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 converter unit as shown in (III). A leakage current containing many high frequency components flows into the earthing (grounding) cables of the converter unit. Because of this, the converter unit 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 536 class 1 and other applicable standards). Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should be the size indicated in the
table on page 29. The earthing (grounding) point should be as close as possible to the converter unit, 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.

2.6.3 Wiring of control circuit Control circuit terminal layout
For manufacturer setting. Do not use.
Wiring method Power supply connection For the control circuit wiring, strip off the sheath of a cable, and use it with a ferrule terminal. For a single wire, strip off the sheath of the wire and apply directly. Insert the ferrule terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with neighboring wires. If the length is too short, wires might come off. Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
(2) Crimp the ferrule terminal. Insert wires to a ferrule terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the ferrule terminal after crimping. Do not use a ferrule terminal of which the crimping is inappropriate, or the face is damaged.
Ferrule terminals commercially available (as of October 2020) Phoenix Contact Co., Ltd.
Caution Do not use the empty terminals (NC) of the control circuit. Doing so may lead to damage of the

Signal inputs by contactless switches The contact input terminals of the converter unit (RES, OH, RDI) can be controlled using a transistor instead of a contact switch as shown below.
2.6.4 Wiring precautions It is recommended to use a cable of 0.75 mm2 for connection to the control circuit terminals. The wiring length should be 30 m 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 200 V 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 the 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) via a relay coil, lamp, etc. Separate the wiring of the control circuit away from the wiring of the main circuit.
Make cuts in rubber bush of the converter unit side and lead the wires through.

Terminal screw size: M4
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 converter unit 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. Do not connect the power cable to incorrect terminals. Doing so may damage the converter unit.
(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 converter unit 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 converter unit is reset and a fault output will
not be held. When a power supply is provided for the control circuit separately from the main circuit and a capacitive device (such as an
EMC filter or a radio noise filter) is connected, connect a noise filter (example: RTMN5006 manufactured by TDK-Lambda Corporation) to the control circuit power supply.

2.6.6 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 converter unit'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 October 2013)
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 the 24 V external power supply operation and enables the normal operation.
NOTE When the 24 V external power is supplied while the main circuit power supply is OFF, the converter unit 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 converter unit, then the power supply changes to the main circuit power supply.
Confirming the 24 V external power supply input During the 24 V external power supply operation, the alarm lamp flickers.
During the 24 V external power supply operation, the 24 V external power supply operation signal (EV) is output. To use the EV signal, set "68 (positive logic) or 168 (negative logic)" in one of Pr.190 to Pr.195 (output terminal function selection) to assign function to an output terminal.
Operation while the 24 V external power is supplied Faults history and parameters can be read and parameters can be written using the operation panel keys. During the 24 V external power supply operation, monitored items and signals related to inputs to main circuit power supply,
such as input current, converter output voltage, and IPF signal, 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 converter reset or turn OFF then ON the power to reset the faults. The retry function is invalid for all alarms during the 24 V external power supply.

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 converter unit 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 converter units, the current increases when it flows through the converter unit wiring near the power supply. The increase of the current causes voltage to drop further. Use the converter units 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.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).

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 I/O cables or other cables of the inverter or the converter unit 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 or the converter unit'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 output cables of the inverter or the converter unit 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 input side of the inverter or the converter unit. 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.)

3.1.2 Countermeasures against EMI generated by the inverter or the converter unit
Some electromagnetic noises enter the inverter or the converter unit to cause the inverter or the converter unit 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. If these electromagnetic noises cause peripheral devices to malfunction, EMI countermeasures 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, 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 the inverter or the converter unit 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 47) to signal cables. - Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.
PRECAUTIONS FOR USE OF THE CONVERTER UNIT 45
Electro-magnetic interference (EMI) and leakage currents
Techniques to reduce electromagnetic noises that are radiated by the inverter or the 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 their main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close to the main circuit cables, 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 or the converter unit, 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 their I/O cables.
Do not run the signal cables and power cables (I/O cables of the inverter or the converter unit) in parallel with each other and do not bundle them.
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 I/O cables of the inverter or the converter unit. Do not run the signal cables and power cables (I/O cables of the inverter or the converter unit) 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, noises generated from the inverter or the converter unit may flow back through the power supply cables to cause malfunction of the devices and the following countermeasures must be taken: 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.

Power supply harmonics
3.2 Power supply harmonics The inverter or the converter unit 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 input side of the inverter or the converter unit, or in the DC circuit.
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.
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 or the converter unit 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. The converter unit (FR-CC2) is equipped with the DC reactor.

Power-OFF and magnetic contactor (MC)

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 14 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 JEM1038-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 on the left, always use the start signal (ON or OFF of STF(STR) signal) to make a start or stop.
Install a stepdown transformer. 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 38 for removal of the jumper.)

PRECAUTIONS FOR USE OF THE CONVERTER UNIT 49
Power-OFF and magnetic contactor (MC)
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. When an MC is provided to switch to a commercial power supply, for example, it is recommended to use the electronic bypass function Pr.135 to Pr.139. (The commercial power supply operation is not available with vector control dedicated motors nor with PM motors.)
Handling of the manual contactor on the inverter's output side A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor terminals while the motor is running even after the inverter power is turned OFF. In an application where the PM motor is driven by the load even after the inverter is powered OFF, a low-voltage manual contactor must be connected at the inverter's output side.
NOTE Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower,
where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.
Do not open or close the contactor while the inverter is running (outputting).
50 PRECAUTIONS FOR USE OF THE CONVERTER UNIT
Checklist before starting operation
3
3.5 Checklist before starting operation The FR-CC2 converter unit is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following points.
Checkpoint Countermeasure Refer
to page
Check by user
Crimping terminals are insulated. Use crimping terminals with insulation sleeves to wire the power supply and the inverter.
No wire offcuts are left from the time of wiring.
Wire offcuts can cause an alarm, failure or malfunction. Always keep 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 converter unit.
The main circuit cable gauge is correctly selected. Use an appropriate cable gauge to suppress the voltage drop to 2% or less. 29
The total wiring length is within the specified length.
Keep the total wiring length within the specified length. In long distance wiring, charging currents due to stray capacitance in the wiring may cause the equipment on the converter unit's output side to malfunction. Pay attention to the total wiring length.
29
Countermeasures are taken against EMI.
The input/output (main circuit) of the converter unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the converter unit. In such a case, install a noise filter to minimize interference.
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 converter unit is low enough using a tester, etc.
The voltage applied to the converter unit I/O signal circuits is within the specifications.
Application of a voltage higher than the permissible voltage to the converter unit I/O signal circuits or opposite polarity may damage the I/O devices. Check the wiring beforehand.
31
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 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 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 JEM1038-AC-3 class rated current.
49
The specifications and rating match the system requirements.
Make sure that the specifications and rating match the system requirements.
The converter unit and the inverter are correctly connected.
Make sure that the terminal P/+ of the converter unit and the terminal P/+ of the inverter, and the terminal N/- of the converter unit and the 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 the terminals P/+ and N/- (across terminals P and P/+ or across N and N/-).
Always connect the terminal RDA of the converter unit and the terminal MRS (X10) of the inverter, and the terminal SE of the converter unit and the terminal SD (terminal PC for source logic) of the inverter. Not connecting these terminals may damage the converter unit.

4.2.1 Real time clock function
Simple clock function When the year, month, day, time and minute are set in the parameters, the converter unit counts the date and time. The
date and time can be checked by reading the parameters.
NOTE The clock's count-up data is saved in the inverter's EEPROM every 10 minutes. The clock does not count up while the control circuit power supply is OFF. The clock function must be reset after turning ON
the power supply. Use a separate power supply, such as an external 24 V power supply, for the control circuit of the simple clock function, and supply power continuously to this control circuit.
Converter reset is performed if supplying power to the main circuit power supply is started with power supplied only to the control circuit power supply. Thus, the clock information stored in the EEPROM is restored. Reset at the start of supplying power to the main circuit can be disabled by setting Pr.30 Reset selection during power supply to main circuit. (Refer to page 81)
The set clock is also used for functions such as faults history.
The time can be set. The time can only be updated while the converter unit power is ON. The real time clock function is enabled using an optional LCD operation panel (FR-LU08).

PARAMETER 59
(E) Environment setting parameters
Real time clock function When the FR-LU08 is connected to the inverter, the clock of FR-LU08 is synchronized with the internal clock of the inverter.
(Real time clock function) With a battery (CR1216), the FR-LU08 time count continues even if the main power of the inverter is turned OFF. (The time count of the inverter internal clock does not continue when the inverter power is turned OFF.)
When the time is set using the inverter parameters, the time of FR-LU08 is set to the time of inverter internal clock.
NOTE Time adjustment between the inverter internal clock and the FR-LU08 is performed every one minute. If the time of the FR-LU08 progresses faster than the time of inverter internal clock, the FR-LU08 time setting is valid. When the FR-LU08 clock is initialized, the inverter internal clock is valid.

4.2.2 Reset selection / disconnected PU detection / reset limit
Reset selection (P.E100) When P.E100="1" or Pr.75="15, 17, 115, or 117", reset (reset command via RES signal or communication) input is enabled
only when the protective function is activated.
NOTE When the reset signal (RES) is input during operation, the inverter is also reset. The motor coasts since the inverter being
reset shuts off the output. Also, the cumulative value of electronic thermal O/L relay is cleared. The input of the PU reset key is only enabled when the protective function is activated, regardless of the P.E100 and Pr.75
settings.
Disconnected PU detection (P.E101) If the PU is detected to be disconnected from the converter unit for 1 s or longer while P.E101="1" or Pr.75="16, 17, 116 or
117", PU disconnection (E.PUE) is displayed and the inverter output is shut off.
NOTE When the PU has been disconnected since before power-ON, the output is not shut off. To restart, confirm that the PU is connected and then reset. When RS-485 communication operation is performed through the PU connector, the reset selection is valid but the
disconnected PU detection function is invalid. (The communication is checked according to Pr.122 PU communication check time interval.)
The reset input acceptance, the disconnected PU connector detection function, and the reset limit function can be selected.

Life alarm display and signal output (Y90 signal, Pr.255) Whether or not the parts of the control circuit capacitor, cooling fan, or inrush current limit circuit have reached the life alarm
output level can be checked with Pr.255 Life alarm status display and the life alarm signal (Y90).
The life alarm signal (Y90) turns ON when any of the control circuit capacitor, cooling fan, or inrush current limit circuit reaches the life alarm output level.
For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of Pr.190 to Pr.195 (output terminal function selection).
NOTE Changing the terminal assignment using Pr.190 and Pr.195 (output terminal function selection) may affect the other

4.2.8 Maintenance timer alarm
The cumulative energization time of the converter unit is stored in the EEPROM every hour and displayed in Pr.503 (Pr.686, Pr.688) in 100 h increments. Pr.503 (Pr.686, Pr.688) is clamped at 9998 (999800 h).
When the value in Pr.503 (Pr.686, Pr.688) reaches the time (100 h increments) set in Pr.504 (Pr.687, Pr.689),Maintenance timer signal (Y95) is output, and also MT1, MT2, or MT3 is displayed on the operation panel.
For the terminal used for Y95 signal output, assign the function by setting "95 (positive logic)" or "195 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection).
NOTE The Y95 signal turns ON when any of MT1, MT2 or MT3 is activated. It does not turn OFF unless all of MT1, MT2 and MT3
are cleared. If all of MT1, MT2 and MT3 are activated, they are displayed in the priority of "MT1 > MT2 > MT3". The cumulative energization time is counted every hour. Energization time of less than 1 h is not counted. Changing the terminal assignment using Pr.190 and Pr.195 (output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Parameters referred to Pr.190 to Pr.195 (output terminal function selection) page 75
The maintenance timer output signal (Y95) is output when the converter unit's cumulative energization time reaches the time period set with the parameter. MT1, MT2 or MT3 is displayed on the operation panel. This can be used as a guideline for the maintenance time of peripheral devices.

4.3.1 Initiating a protective function
To initiate a fault (protective function), set the assigned number of the protective function you want to initiate in Pr.997. The value set in Pr.997 is not stored in EEPROM. When a protective function is activated, the inverter trips, a fault is displayed, and a fault signal (ALM, ALM2) is output. The latest fault in the faults history is displayed while the fault initiation function is in operation. After a reset, the faults
history goes back to the previous status. (The protective function generated by the fault is not saved in the faults history.) Perform converter reset to cancel the protective function. For the selectable parameter by Pr.997 and the corresponding protective functions, refer to page 121.
NOTE If a protective function is already operating, no protective function cannot be initiated by Pr.997. The retry function is disabled when a protective function has been initiated by fault initiation function. If a fault occurs after a protective function has been activated, the protective function indication does not change. The fault is
not saved in the faults history either.
4.3.2 Input phase loss protection selection
When Pr.872 = "1", the Input phase loss (E.ILF) protection will be activated if one of three phases is detected to be lost for 1 s continuously.
NOTE In the case of R/L1, S/L2 phase loss, the input phase loss protection will not operate, and the inverter will trip. If an input phase loss continues for a long time, the converter unit capacitor life will be shorter.

4.3.3 Retry function
Setting the retry function (Pr.67, Pr.68) When the converter unit protective function is operating (fault indication), the retry function automatically cancels (resets)
the protective function after the time set in Pr.68. Retry operation is enabled when Pr.67 "0". For Pr.67, set the number of retries at activation of the protective function.
When retries fail consecutively more than the number of times set in Pr.67, a Retry count excess (E.RET) occurs. (Refer to the retry failure example.)
For Pr.68, set the waiting time from a protective function activation to a retry in the range of 0.1 to 600 s. During retry operation, the During retry (Y64) signal is ON. For the Y64 signal, assign the function by setting "64 (positive
logic)" or "164 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection).
If a protective function activates (fault display), the converter unit resets itself automatically to restart. The retry generating protective functions can be also selected. When the automatic restart after instantaneous power failure function is selected (Pr.57 "9999"), the restart operation is also performed after a retry operation as well as after an instantaneous power failure. (Refer to page 83 for the restart operation.)

PARAMETER 69
(H) Protective function parameter
Retry count check (Pr.69) By reading Pr.69, the number of successful restarts made by retries can be obtained. The cumulative count in Pr.69
increases by 1 when a retry is successful. Retry is regarded as successful when normal operation continues without a fault for the Pr.68 setting multiplied by four or longer (3.1 s at the shortest). (When retry is successful, the cumulative number of retry failures is cleared.)
Writing "0" in Pr.69 clears the cumulative count.
Selecting retry generating faults (Pr.65) Using Pr.65, you can select the fault that will cause a retry. No retry will be made for the fault not indicated. (For the fault
details, refer to page 122.) indicates the faults selected for retry.
NOTE Use the retry function only when the operation can be resumed after resetting a protective function activation. Making a retry
against the protective function, which is activated by an unknown condition, will lead the converter unit to be faulty. Identify what condition the protective function was activated, and eliminate such condition before resuming the operation.
Only the fault details for the first fault that occurred are stored in the faults history. The reset by the retry function does not clear the accumulated data of the electronic thermal O/L relay, etc. (This is different
from power supply reset or reset by RES signal.) When the parameter storage device fault (E.PE) has occurred and reading of the retry-function-related parameters has failed,
the retry operation cannot be performed. Changing the terminal assignment using Pr.190 to Pr.195 (output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Parameters referred to Pr.57 Restart selection page 83
Caution When the retry function is set enabled, stay away from the motor and machine in the case of an
inverter trip. The motor and machine will start suddenly (after the reset time has elapsed) after the inverter trip. If the retry function has been selected, apply the CAUTION stickers, which are supplied with the Inverter Manual, to easily visible places.

Cumulative power monitor and clear (Pr.170, Pr.891) On the cumulative power monitor (Pr.774 to Pr.776 = "25"), the input power monitor value is added up and updated in 100
ms increments. (The values are saved in EEPROM every hour.) Display increments and display ranges of the operation panel and communication (RS-485 communication) are as
indicated below.
Power is measured in the range of 0 to 99999.99 kWh, and displayed in five digits. When the monitor value exceeds "999.99", a carry occurs, for example "1000.0", so the value is displayed in 0.1 kWh increments.
Digits in the cumulative power monitor can be shifted to the right for the numerical set in Pr.891 Cumulative power monitor digit shifted times. For example, if the cumulative power value is 1278.56 kWh when Pr.891 = "2", the operation panel display is 12.78 (display in 100 kWh increments) and the communication data is 12.
If the maximum value is exceeded at Pr.891 = "0 to 4", the monitor value is clamped at the maximum value, indicating that a digit shift is necessary. If the maximum value is exceeded at Pr.891 = "9999", the monitor value returns to 0, and the counting starts again.
Writing "0" in Pr.170 clears the cumulative power monitor.
NOTE If "0" is written to Pr.170, and Pr.170 is read again, "9999" or "10" is displayed.
Cumulative energization time monitor (Pr.563) Cumulative energization time monitor (Pr.774 to Pr.776 = "20") accumulates energization time from shipment of the
converter unit every one hour. If the number of monitor value exceeds 65535, it is added up from 0. Use Pr.563 to check the numbers of times that the
cumulative energization time monitor exceeded 65535 h. Writing "0" in Pr.171 clears the actual operation time monitor. (The energization time monitor cannot be cleared.)
NOTE The cumulative energization time does not increase if the power is ON for less than an hour.
Hiding the decimal places for the monitors (Pr.268) The numerical figures after a decimal point displayed on the operation panel may have small fluctuations during analog
input, etc. The decimal places can be hidden by selecting the decimal digits with Pr.268.
NOTE The number of display digits on the cumulative energization time (Pr.774 to Pr.776="20") and the cumulative power (Pr.774
to Pr.776="25") does not change.

Cooling fan operation command signal (Y206) The cooling fan operation command signal (Y206 signal) can be output when the converter unit cooling fan meets the
conditions for running. The function can be used when the fan installed on the enclosure is synchronized with the converter unit cooling fan.
Y206 signal indicates the operating command condition of the converter unit cooling fan depending on the power supply ON/OFF. The signal does not indicate the actual operation of the cooling fan. (The signal is output even if the cooling fan is stopped due to a fault.)
To use the Y206 signal, set "206 (positive logic) or 306 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection) to assign the function to the output terminal.
NOTE Changing the terminal assignment using Pr.190 to Pr.195 (output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Inverter operation enable signals (RDA and RDB) and inverter reset signal (RSO)
Fault output signals (ALM, ALM2)
NOTE For the details of converter unit faults, refer to page 122.
The inverter operation enable (NO contact) (RDA) signal turns ON when the converter unit operation is ready, and turns OFF when a converter unit fault occurs or the converter is reset.
A logic inverse to that of RDA is applied to the inverter operation enable (NC contact) (RDB) signal. (However, the RDB signal is in the OFF status while the converter unit power supply is turned OFF.)
The RDA and RDB signals are initially assigned to the terminals RDA and RDB respectively. By setting "11" for the RDA signal or "111" for the RDB signal in either Pr.190 to Pr.195 (output terminal function selection) , the signals can be assigned to other terminals.
When the converter reset (RES) signal is input to the converter unit, the inverter reset (RSO) signal is output to the inverter.
The RSO signal is assigned to the terminal RSO in the initial status. The RSO signal can also be assigned to other terminals by setting "209 (positive logic) or 309 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection).
The Fault (ALM, ALM2) signals are output when the converter unit protective function is activated.
The ALM2 signal stays ON during the reset period after the fault occurs.
To use the ALM2 signal, set "94 (positive logic) or 194 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection) to assign the function to the output terminal.
The ALM signal is assigned to the A1B1C1 contacts in the initial status.

(A) Application parameters
Operation of the self power management function This is a function to control the input side magnetic contactor (MC) with an output relay to reduce standby power. Use
separate power supplies for the main circuit and the control circuit by using terminals R1/L11 or S1/L21 (refer to page 38) and 24 V external power supply input (refer to page 39). Control the main circuit power supply MC by the electronic bypass MC1 signal of the inverter.
Set Pr.248 Self power management selection = "1 or 2", and Pr.190 to Pr.195 (output terminal function selection) = "17 (positive logic)" to assign the control signal for main circuit power supply MC (Y17 signal) to an output terminal. (Set Pr.248 in accordance with the Pr.248 setting of the inverter.)
Y17 signal turns ON while the self power management function is enabled. When the protective function of the converter unit is activated, Y17 signal immediately turns OFF according to the Pr.248
setting. When Pr.248 = "1", Y17 signal turns OFF whenever a protective function is activated. When Pr.248 = "2", Y17 signal turns OFF only when a protective function is activated by a fault originating in the converter unit circuit or a connection fault (refer to the table below). (For the fault details, refer to page 122.)
To enable the self power management function for the separated converter type, enable the self power management function also on the converter unit side. To activate the self power management function when a converter unit fault occurs, connect the terminal to which Y17 signal of the converter unit is assigned and the terminal to which X94 signal of the inverter is assigned.
NOTE When the retry function is used for resetting during self power management operation, Y17 signal retains the value before the
reset. Repeated operation of the magnetic contactor due to frequent start and stop or activation of the protective function may
shorten the inverter and the converter unit life. Changing the terminal assignment using Pr.190 to Pr.195 (output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Selection between resetting or not resetting during power supply to main circuit (Pr.30 = "100")
Converter reset is not performed if Pr.30 Reset selection during power supply to main circuit = "100", and supplying power to the main circuit (R/L1, S/L2, T/L3 input) is started when power is supplied only to the control circuit (R1/L11, S1/ L12 input, or 24 V external power supply input).

0 Restarts the motor after power restoration from instantaneous power failure
9999 Does not restart the motor.
When the automatic restart after instantaneous power failure is selected on the inverter side, set Pr.57 Restart selection = "0" on the converter unit side.
When the automatic restart after instantaneous power failure function is set, the motor is restarted after power restoration from instantaneous power failure or undervoltage condition. (E.IPF and E.UVT are not activated.)
When Pr.57 = "9999" (initial value), the inverter output is shut off at the activation of the instantaneous power failure protection (E.IPF or E.UVT) of the converter unit, even when the automatic restart after instantaneous power failure is selected on the inverter side. (Refer to page 122 for E.IPF or E.UVT.)
When E.IPF or E.UVT is activated, the Instantaneous power failure/ undervoltage (IPF) signal is output.
The IPF signal is assigned to the terminal IPF in the initial status. The IPF signal can also be assigned to other terminals by setting "2 (positive logic) or 102 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection).
Caution If the automatic restart after instantaneous power failure function has been selected, motor suddenly
restarts at the power restoration after an instantaneous power failure (after the reset time has elapsed). Stay away from the motor and machine. If the automatic restart after instantaneous power failure function has been selected, apply the CAUTION stickers, which are supplied with the Inverter Manual, to easily visible places.

4.7.3 Initial setting of operation via communication
Setting the communication protocol (Pr.549) Select the communication protocol. The MODBUS RTU protocol can be used by communication from the RS-485 terminals.
Communication EEPROM write selection (Pr.342) Storage device of the parameter setting can be changed to RAM only from EEPROM+RAM for the parameter writing from
the RS-485 communication via the converter unit PU connector or the RS-485 terminals. Use this function if parameter settings are changed frequently.
When changing the parameter values frequently, set "1" in Pr.342 Communication EEPROM write selection to write them to the RAM only. The life of the EEPROM will be shorter if parameter write is performed frequently with the setting unchanged from "0 (initial value)" (EEPROM write).
NOTE Turning OFF the converter unit's power supply clears the modified parameter settings when Pr.342 = "1 (write only to RAM)".
Therefore, parameter settings at next power-ON will be the ones that are last stored to EEPROM. The parameter setting written in RAM cannot be checked on the operation panel. (The values displayed on the operation
panel are the ones stored in EEPROM.)
Set the action when the converter unit is performing operation via communication. Set the communication protocol. (Mitsubishi inverter protocol/MODBUS RTU protocol) Set the action at fault occurrence or at writing of parameters.

4.7.5 Mitsubishi inverter protocol (computer link communication)
Communication specifications The communication specifications are given below.
Communication procedure Data communication between the computer and the converter unit is made in the following procedure.
(a) Request data is sent from the computer to the converter unit. (The converter unit will not send data unless requested.) (b) After waiting for the waiting time, (c) The converter unit sends reply data to the computer in response to the computer request. (d) After waiting for the converter unit data processing time, (e) An answer from the computer in response to reply data (c) of the converter unit is transmitted. (Even if (e) is not sent,
subsequent communication is made properly.)
If a data error is detected and a retry must be made, perform retry operation with the user program. The converter unit trips when the number of consecutive retries exceeds the parameter setting.
On receipt of a data error occurrence, the converter unit returns reply data (c) to the computer again. The converter unit trips when the number of consecutive data errors exceeds the parameter setting.
Parameter settings and monitoring are possible by using the Mitsubishi inverter protocol (computer link communication) via inverter PU connector and the RS-485 terminals.

Retry count setting (Pr.121, Pr.335) Set the permissible number of retries for data receive error occurrence. (Refer to page 98 for data receive error for retry.) When the data receive errors occur consecutively and the number of retries exceeds the permissible number setting, a
communication fault (PU connector communication: E.PUE, RS-485 terminal communication: E.SER) occurs and the inverter trips.
When a data transmission error occurs while "9999" is set, the inverter does not trip but outputs the Alarm (LF) signal. To use the LF signal, set "98 (positive logic) or 198 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection) to assign the function to an output terminal.
Signal loss detection (Pr.122, Pr.336) If a signal loss (communication stop) is detected between the converter unit and the computer as a result of a signal loss
detection, a communication fault (PU connector communication: E.PUE, RS-485 terminal communication: E.SER) occurs and the inverter trips.
When the setting is "9999", communication check (signal loss detection) is not made. When the setting is "0", communication from the PU connector is not possible. The monitored items and parameter settings
can be read during communication via RS-485 terminals, but a communication error (E.SER) occurs. A signal loss detection is made when the setting is any of "0.1 s to 999.8 s". To make a signal loss detection, it is necessary
to send data (for details on control codes, refer to page 97) from the computer within the communication check time interval. (The converter unit makes a communication check (clearing of communication check counter) regardless of the station number setting of the data sent from the master.)

(N) Operation via communication and its settings
Instructions for the program When data from the computer has any error, the converter unit does not accept that data. Hence, in the user program,
always insert a retry program for data error. All data communication, for example, monitoring, are started when the computer gives a communication request. The
converter unit does not return any data without the computer's request. Hence, design the program so that the computer gives a data read request for monitoring, etc. as required.

Caution Always set the communication check time interval before starting operation to prevent hazardous
conditions. Data communication is not started automatically but is made only once when the computer provides
a communication request. If communication is disabled during operation due to signal cable breakage etc., the inverter cannot be stopped. When the communication check time interval has elapsed, the inverter will trip (E.PUE, E.SER). The inverter can be coasted to a stop by switching ON the RES signals or by switching the power OFF.
If communication is broken due to signal cable breakage, computer fault etc., the converter unit does not detect such a fault. This should be fully noted.

PARAMETER 105
(N) Operation via communication and its settings
Overview The MODBUS communication protocol was developed by Modicon for programmable controllers. The MODBUS protocol uses exclusive message frames to perform serial communication between a master and slaves.
These exclusive message frames are provided with a feature called "functions" that allows data to be read or written. These functions can be used to read or write parameters from the converter unit, or check the converter unit's operating status, for example. This product classifies the data of each converter unit into holding register area (register address 40001 to 49999). The master can communicate with converter units (slaves) by accessing preassigned holding register addresses.
NOTE There are two serial transmission modes, the ASCII (American Standard Code for Information Interchange) mode and the
RTU (Remote Terminal Unit) mode. However, this product supports only the RTU mode, which transfers 1 byte data (8 bits) as it is. Also, only communication protocol is defined by the MODBUS protocol. Physical layers are not stipulated.
Message format
Data check time
Query A message is sent to the slave (for instance, the converter unit) having the address specified by the master.
Normal Response After the query from the master is received, the slave executes the requested function, and returns the corresponding normal response to the master.
Error Response When an invalid function code, address or data is received by the slave, the error response is returned to the master. This response is appended with an error code that indicates the reason why the request from the master could not be executed. This response cannot be returned for errors detected by the hardware, frame error, and CRC check error.
Broadcast The master can broadcast messages to all slaves by specifying address 0. All slaves that receive a message from the master execute the requested function. With this type of communication, slaves do not return a response to the master.
NOTE During broadcast communication, functions are executed regarded of the converter unit station number (Pr.331) setting.

Message frame (protocol) Communication method
Basically, the master sends a Query message (question), and slaves return the Response message (response). At normal communication, the Device Address and Function Code are copied as they are, and at erroneous communication (illegal function code or data code), bit 7 (= H80) of the Function Code is turned ON, and the error code is set at Data Bytes.
Message frames comprise of the four message fields shown in the figures above. A slave recognizes message data as a message by the message data being prefixed and appended with a no data time of 3.5 characters (T1: start/end).
Details of protocol The following table explains the four message fields.

Message field Description
ADDRESS field
For the address, 0 to 247 can be set in single byte lengths (8 bits). Set "0" when sending broadcast messages (instructions to all addresses), and "1 to 247" to send messages to individual slaves. The address set by the master is also returned when the response is sent from the slave. The value set to Pr.331 RS-485 communication station number is the slave address.
FUNCTION field
For the function code, 1 to 255 can be set in single byte lengths (8 bits). The master sets the function to be sent to the slave as the request, and the slave performs the requested operation. For the supported function codes, refer to the "Function code list" on page 108. An error response is generated when a function code other than one in the "Function code list" is set. At a response from the slave, the function code set by the master is returned in the case of a normal response. At an error response, H80 + the function code is returned.
DATA field The format changes according to the function code. (Refer to page 109.) The data, for example, includes the byte count, number of bytes, and accessing content of holding registers.
CRC CHECK field
Errors in the received message frame are detected. Errors are detected in the CRC check, and the message is appended with data 2 bytes long. When the message is appended with the CRC, the lower bytes are appended first, followed by the upper bytes. The CRC value is calculated by the sender that appends the message with the CRC. The receiver recalculates the CRC while the message is being received, and compares the calculation result against the actual value that was received in the error check field. If the two values do not match, the result is treated as an error.

An error does not occur in the following cases: Function code H03 (read data of holding register) When there are 1 or more number of reads (No. of Points) and there is 1 or more holding register from where data can be read. Function code H10 (write data to multiple holding registers) When there are 1 or more number of writes (No. of Points) and there is 1 or more holding registers to which data can be written. In other words, when function code H03 or H10 is used and multiple holding registers are accessed, an error will not occur even if a non-existent holding register or a holding register that cannot be read or written is accessed.
NOTE An error will occur if all accessed holding registers do not exist. The data read value of non-existent holding registers is 0, and
data is invalid when written to non-existent holding registers.

Signal loss detection (Pr.539 MODBUS RTU communication check time interval)
If a signal loss (communication stop) is detected between the converter unit and the master as a result of a signal loss detection, a Communication fault (inverter) (E.SER) occurs and the inverter trips.
When the setting is "9999", communication check (signal loss detection) is not made. The monitored items and parameter settings can be read when "0" is set, but E.SER occurs. A signal loss detection is made when the setting is any of "0.1 s to 999.8 s". To make a signal loss detection, it is necessary
to send data from the master within the communication check time interval. (The inverter makes a communication check (clearing of communication check counter) regardless of the station number setting of the data sent from the master.)
The communication check time by query communication includes a no data time (3.5 bytes). This no data time differs according to the communication speed, so take this no data time into consideration when setting the communication check time.

Converter unit fault and alarm indications
120 PROTECTIVE FUNCTIONS
5.1 Converter unit fault and alarm indications When the converter unit detects a fault, depending on the nature of the fault, the operation panel displays an error message
or warning, or a protective function activates to trip the inverter. When a protective function is activated, take an appropriate corrective action, then reset the converter unit (inverter), and
resume the operation. Restarting the operation without a reset may break or damage the converter unit (inverter). When a protective function is activated, note the following points.
Converter unit fault or alarm indications are categorized as below.
NOTE The past eight faults can be displayed on the operation panel. (Faults history) (For the operation, refer to the FR-LU08
Instruction Manual.)
5.2 Reset method for the protective functions Reset the converter unit 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 converter unit. The converter unit recovers about 1s after the reset is released.
NOTE Resetting a converter unit fault with the inverter start signal ON restarts the inverter suddenly. OFF status of the inverter start
signal must be confirmed before resetting.
Item Description
Fault output signal Opening the magnetic contactor (MC) provided on the input side of the converter unit at a fault occurrence shuts off the control power to the converter unit, therefore, the fault output will not be retained.
Fault or alarm indication When a protective function is activated, the operation panel displays a fault indication.
Operation restart method While a protective function is activated, the inverter output is kept shutoff. Reset the converter unit (inverter) to restart the operation.
Displayed item Description
Error message A message regarding an operational fault and setting fault by the operation panel is displayed. The inverter does not trip.
Warning The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a fault.

When the heatsink overheats, the temperature sensor activates, and the inverter output is stopped. The FIN signal can be output when the temperature reaches approximately 85% of the heatsink overheat protection operation temperature. For the terminal used for the FIN signal output, assign the function by setting "26 (positive logic) or 126 (negative logic)" in any of Pr.190 to Pr.195 (output terminal function selection). (Refer to page 75.)
Check point Check for too high surrounding air temperature. Check for heatsink clogging. Check that the cooling fan is not stopped. (Check that FN is not displayed on the operation panel.)
Corrective action Set the surrounding air temperature to within the specifications. Clean the heatsink. Replace the cooling fan.
Abbreviation E.IPF Name Instantaneous power failure
Description
If a power failure occurs for longer than 15 ms (this also applies to converter unit input shut-off), the instantaneous power failure protective function is activated to trip the inverter in order to prevent the control circuit from malfunctioning. If a power failure persists for 100 ms or longer, the fault output is not provided, and the inverter restarts if the inverter start signal is ON upon power restoration. (The inverter continues operating if an instantaneous power failure is within 15 ms.) In some operating status (load magnitude, acceleration/deceleration time setting, etc.), overcurrent or other protection may be activated by the inverter upon power restoration. When instantaneous power failure protection is activated, the IPF signal is output. (Refer to page 83.)
Check point Find the cause of the instantaneous power failure occurrence.
Corrective action Recover from the instantaneous power failure condition. Prepare a backup power supply in case of an instantaneous power failure. Set the function of automatic restart after instantaneous power failure (Pr.57). (Refer to page 83.)
Abbreviation E.UVT Name Undervoltage
Description
If the power supply voltage of the converter unit decreases, the control circuit will not perform normal functions. In addition, the motor torque will be insufficient and/or heat generation will increase. To prevent this, if the power supply voltage decreases to about 440 VAC or below, this function shuts off the inverter output. When undervoltage protection is activated, the IPF signal is output. (Refer to page 83.)
Check point Check if a high-capacity motor is driven.
Corrective action Check the power supply system equipment such as the power supply. If the problem still persists after taking the above measure, contact your sales representative.

6.1.4 Checking the converter semiconductor devices Preparation Disconnect the external power supply cables (R/L1, S/L2, T/L3, P/+, and N/-). Prepare a continuity tester. (For the resistance measurement, use the 100 range.)
Checking method Change the polarity of the tester alternately at the converter unit terminals R/L1, S/L2, T/L3, P/+, and N/- and 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.
Semiconductor device numbers and terminals to be checked
(Assuming that an analog meter is used.)
6.1.5 Cleaning Always run the converter unit in a clean status. When cleaning the converter unit, 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 converter unit surface paint to
peel off. The display, etc. of the operation panel are vulnerable to detergent and alcohol. Therefore, avoid using them for cleaning.

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.
The number of cooling fans differs according to the converter unit capacity.
Reinstallation 1) After confirming the orientation of the fan, reinstall the fan so that the "AIR FLOW" faces up.
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 converter unit life to be shorter. Prevent the cable from being caught when installing a fan. Switch the power OFF before replacing fans. Since the converter unit circuits are charged with voltage even after power OFF,
replace fans only when the converter unit cover is on the converter unit to prevent an electric shock accident.

Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the surrounding air temperature and operating conditions. When the converter unit is operated in air-conditioned, normal environment conditions, replace the capacitors about every 10 years. The appearance criteria for inspection are as follows: Case: Check the side and bottom faces for expansion. Sealing plate: Check for remarkable warp and extreme crack. heck for external crack, discoloration, liquid leakage, etc. Judge that the capacitor has reached its life when the measured
capacitance of the capacitor reduced below 80% of the rating.
NOTE The converter unit diagnoses the control circuit capacitor by itself and can judge its life. (Refer to page 65.)
Relays To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching life).
Main circuit fuse A fuse is used inside the converter unit. The replacement intervals vary with the surrounding air temperature and operating conditions. When the converter unit is operated in air-conditioned, normal environment conditions, replace the capacitors about every 10 years.
6.1.7 Converter unit replacement The converter unit can be replaced with the control circuit wiring kept connected. 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 converter unit's control circuit connector, reinstall the control circuit terminal block, and fix it with the mounting screws.
NOTE Before starting converter unit replacement, switch power OFF, wait for at least 10 minutes, and then check the voltage with a
tester and such to ensure safety.
Loosen the screws

6.2 Measurement of main circuit voltages, currents and powers
Since the voltages and currents on the converter unit 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 converter unit output side
When the wiring length between the converter unit and the inverter is large, the meters and CTs may generate heat due to line-to-line leakage current. Therefore, choose the equipment which has enough allowance for the current rating.
Measuring points and instruments
When the setting of Pr.195 ABC1 terminal function selection is the positive logic

PRECAUTIONS FOR MAINTENANCE AND INSPECTION 139
Measurement of main circuit voltages, currents and powers
6.2.2 Measurement of voltages Use a digital power meter (for inverter) for the input side of the converter unit.
6.2.3 Measurement of currents Use a digital power meter (for inverter) for the input side of the converter unit. 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. The converter unit input current can be monitored on the operation panel. The value displayed on the operation panel is accurate. Hence, it is recommended to monitor values on the operation panel. Install the operation panel of the inverter on the converter unit.
6.2.4 Example of measuring converter unit input power factor
Calculate the factor from the effective power and the apparent power. A power-factor meter cannot indicate an exact value.
6.2.5 Measurement of converter output voltage (across terminals P and N)
The output voltage of the converter can be measured with a voltmeter (such as a digital multimeter) between terminals P and N. The voltage varies according to the power supply voltage. Approximately 540 to 600 VDC is output when no load is applied. The voltage decreases when a load is applied. When energy is regenerated from the motor during deceleration, for example, the converter output voltage rises to nearly 800 to 900 VDC maximum.
6.2.6 Insulation resistance test using megger For the converter unit, conduct the insulation resistance test on the main circuit only as follows 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
converter unit so that the test voltage is not applied to the converter unit. For the continuity test of the control circuit, use a tester for high resistance range and do not use the megger or buzzer.
6.2.7 Withstand voltage test Do not conduct a withstand voltage test. Deterioration may occur.

Converter unit rating
7.1 Converter unit rating
The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for the converter unit and the inverter to return to or below the temperatures under 100% load.
The converter unit output voltage varies according to the input power supply voltage and the load. The maximum point of the voltage waveform at the converter unit output side is approximately the power supply voltage multiplied by .
The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including those of the input reactor and cables).
The permissible voltage imbalance ratio is 3% or less. (Imbalance ratio = (highest voltage between lines - average voltage between three lines ) / average voltage between three lines 100)
The overload current rating, the rated input current, and the power supply capacity depend on the inverter rating.
7.2 Common specifications
Temperature applicable for a short time, e.g. in transit. For the installation in an altitude above 1000 m (up to 2500 m), derate the rated current 3% per 500 m. This protective function is not available in the initial status.
