2 INSTALLATION Precautions

Install the converter unit on incombustible material. Installing them either directly on or near combustibles may lead to smoke or a fire. In addition, the converter unit must be installed in a metal cabinet.

Provide an adequate protection to prevent the following matter from entering the converter unit: conductive matter such as screws and metal fragments, and combustible matter such as oil.

The converter unit may become hot. Take safety measures such as providing covers. Do not stack in excess of the specified number of product packages. Do not hold the front cover, cables, or connectors when carrying the converter unit. Doing so may cause the converter unit

to drop. Use the eyebolts of the converter unit for transportation only. Do not use them to transport the converter unit when it is

mounted on a machine. Do not overtighten the eyebolts of the converter unit. Tightening too hard may damage the tap. To prevent a malfunction, do not drop the converter unit or subject it to impact. When installing the converter unit, follow the user's manual and install the unit in a place that can support its weight. Do not get on the equipment or put a heavy load on it. Do not install or operate a converter unit that is missing parts or is damaged. To prevent a malfunction, do not block the intake and exhaust areas of the converter unit. Do not subject connectors to impacts. Doing so may cause a connection failure, malfunction, or other failures. Use the product within the specified environment. For details on the environment, refer to the following. Page 8 Standard specifications To prevent a fire or injury from occurring in the event of an earthquake or other natural disaster, securely install, mount, and

wire the servo amplifier as stated in the user's manual. When the product has been stored for an extended period of time, contact your local sales office. When handling the converter unit, be careful with the edges of the converter unit. Fumigants that are used to disinfect and protect wooden packaging from insects contain halogens (such as fluorine,

chlorine, bromine, and iodine) cause damage if they enter our products. Please take necessary precautions to ensure that any residual materials from fumigants do not enter our products, or perform disinfection and pest control using a method other than fumigation, such as heat treatment. Perform disinfection and pest control on the wooden packaging materials before packing the products.

Provide an external emergency stop circuit to stop the operation and shut-off the power immediately. For equipment in which the moving part of the machine may collide against the load side, install a limit switch or stopper to

the end of the moving part. Do not use the servo amplifier in environments where it is exposed to strong magnetic fields, electric fields, or radiation.

Doing so may cause operation failure or malfunction.

2 INSTALLATION 11

2.1 Mounting direction and clearances Precautions

The converter unit must be installed in the specified direction. To prevent a malfunction, maintain the specified clearances between the converter unit and cabinet walls or other

equipment. Circulate air so that the air at the top and bottom of the converter unit does not stagnate. When using heat generating equipment, install it with full consideration of heat generation so that the converter unit is not

affected. Mount the converter unit on a perpendicular wall in the correct vertical direction.

Installation For details on installation, refer to the drive unit/servo amplifier user's manual and instruction manual.

2.2 Keeping out foreign materials When drilling the cabinet for assembly, prevent drill chips and wire fragments from entering the converter unit. Prevent foreign matter such as oil, water, and metallic dust from entering the converter unit through cooling fans installed in openings in the cabinet or on the ceiling. When installing the cabinet in a place where toxic gas, dirt, and dust exist, conduct an air purge (force clean air into the cabinet from outside to make the internal pressure higher than the external pressure) to prevent such materials from entering the cabinet.

2.3 Inspection items Precautions

Do not disassemble, repair, or modify the product. For repair and parts replacement, contact your local sales office. To prevent a malfunction, do not perform an insulation resistance test (megger test) on the converter unit.

Periodic inspection Perform the following inspections. Check for loose terminal block screws. Retighten any loose screws. Check the cables and the like for scratches or cracks. Inspect them periodically according to operating conditions

especially when the servo motor is movable. Check that the connector is securely connected to the converter unit. Check that the wires are not coming out from the connector. Check for dust accumulation on the converter unit. Check for unusual noise generated from the converter unit. Make sure that the emergency stop circuit operates properly such that an operation can be stopped immediately and a

power is shut off by the emergency stop switch.

2.4 Parts with a service life The service life of the following parts is listed below. In addition, the service life varies depending on the operating methods and environment. If any fault is found in a part, it is necessary to replace it immediately regardless of its service life. For parts replacement, please contact your local sales office.

Smoothing capacitor The service life of the capacitor is 10 years (with a three-phase power supply input) under continuous operation in air- conditioned environments (ambient temperatures of 40 C or less at altitudes of up to 1000 m and 30 C or less at altitudes of over 1000 m and up to 2000 m). Ripple currents or other factors will deteriorate the characteristic of the smoothing capacitor. The service life of the capacitor greatly varies depending on ambient temperature and operating conditions.

Converter unit cooling fan The cooling fan bearings will reach the end of their service life in 10000 hours to 30000 hours. Therefore, the cooling fan must be replaced after two to three years of continuous operation as a guideline. If unusual noise or vibration is found during inspection, the cooling fan must also be replaced. The service life has been calculated in an environment which contains no corrosive gas, flammable gas, oil mist, or dust. The average annual ambient temperature was 40 C.

4.3 Converter unit switch settings and operation panel Forced stop, protection coordination, and magnetic contactor drive output can be configured by setting the converter unit switch. The converter unit status and alarm number can be displayed on the converter unit display (1-digit, 7-segment LED).

Switches If a metal screw driver contacts with the conductive areas, the switches may malfunction. Therefore, use an insulated screw driver instead of a metal screw driver to operate the rotary switch (SW1). Do not set a value other than the listed setting values on the rotary switch for converter setting (SW1). The setting of each switch becomes effective by cycling the main circuit power supply and the control circuit power supply. To enable/disable forced stop, protection coordination, and magnetic contactor drive output, set the rotary switch for converter setting. The following table shows the settings of the rotary switch for converter setting and the combinations for enabling/ disabling each function.

5 SIGNALS AND WIRING Precautions

Insulate the conductive parts of the terminals. Turn off the power and wait for 20 minutes or more until the charge light of the unit turns off. Checking the voltage between

L+ and L- using the tester, etc. is recommended. To prevent failure and malfunction, only the power supply/signal specified in the user's manual should be connected to a

corresponding terminal. To prevent unexpected operation of the servo motor, wire the equipment correctly and securely. Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism. Failing to do so

may cause the cables and connectors to disconnect during operation. Unless stated otherwise, all connection diagrams in this user's manual are sink interface diagrams. Install a surge absorbing diode in the correct direction. Failing to do so may cause the amplifier to malfunction and not to

output signals, disabling protective circuits such as the emergency stop.

If the wires are not properly secured to the terminal block, the poor contact may cause the wires and terminal block to generate heat. Be sure to secure the wires with the specified torque.

Check that no operation signal is being input to the drive unit and servo amplifier before resetting an alarm or releasing the emergency stop. Failing to do so may cause an unexpected operation.

If the power supply is shut off by a molded-case circuit breaker or a fuse, remove the cause and secure safety before switching the power on.

Install the converter unit according to the EMC guidelines because electromagnetic interference may affect the electronic equipment used near the converter unit.

To prevent an electric shock or a fire, do not disassemble, repair, or modify the product. Disassembled, repaired, and/or modified products are not covered under warranty.

Eliminate static electricity before performing actions such as wiring or operating a switch.

5.1 Example power circuit connections Precautions

Connect a magnetic contactor between a power supply and the main circuit power supply (L1/L2/L3) of a converter unit to configure a circuit that shuts off the power supply on the converter unit side because failure of the converter unit may cause smoke and fire if a magnetic contactor is not connected.

Use a configuration that shuts off the main circuit power supply with ALM (Malfunction). Check the converter unit model and use the correct power supply voltage. Exogenous noise or lightning surges may degrade the characteristics of the surge absorber (varistor) built into the

converter unit and damage it. To prevent malfunction, avoid bundling the converter unit's power line (input cable) and signal cables together or running

them parallel to each other. Separate the power lines from the signal cables. Provide adequate protection to prevent an unexpected restart after an instantaneous power failure. Configure wiring so that the main circuit power supply is shut off and the servo-on command is turned off after deceleration

to a stop due to an alarm occurrence, an enabled servo forced stop, or a quick stop command from the controller. Use a molded-case circuit breaker (MCCB) with the input cables of the main circuit power supply.

Magnetic contactor control connector (CN23) By enabling the magnetic contactor drive output, the main circuit power supply can be automatically shut off when an alarm occurs in the converter unit and drive unit. The magnetic contactor drive output can be enabled by setting the rotary switch for converter setting (SW1) of the converter unit to "0" or "4".

When the magnetic contactor drive output is enabled The magnetic contactor can be controlled by connecting the magnetic contactor control connector (CN23) to the coil of the magnetic contactor.

*1 When connecting multiple drive units to one converter unit, configure the system to input the emergency stop input of the controller by the alarm signal of each drive unit, and configure the sequence so that if an alarm occurs in any of the drive units, all the drive units turn to ready-off. Because the drive units and servo amplifiers coast when in ready-off (emergency stop status from the controller), install a dynamic brake when stopping the servo motor.

*2 Use the magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80 ms or less. If forced stop deceleration is enabled when connecting one unit, the bus voltage may drop depending on the main circuit power supply voltage and operation pattern, causing a dynamic brake deceleration during forced stop deceleration. If dynamic brake deceleration is not required, delay the time to turn off the magnetic contactor.

*3 Install an overcurrent protection device (molded-case circuit breaker, fuse, etc.). Page 93 Molded-case circuit breakers, fuses, magnetic contactors

When the converter unit receives a start command from the drive unit, a short circuit occurs between the CN23-1 pin (MC1) and CN23-3 pin (MC2) connected to the AC power supply, and power is supplied to the control circuit of the magnetic contactor. When power is supplied to the control circuit of the magnetic contactor, the magnetic contactor is turned on and the main circuit power supply is turned on to the converter unit. In the following cases, the converter unit opens the connection between CN23-1 pin (MC1) and CN23-3 pin (MC2) to automatically turn off the main circuit power supply.

Connecting the CN25 Use care not to damage the conductor when stripping wires. Using a damaged conductor may cause poor insulation, loose connection, and missing wires. After completing the connection, pull the wires lightly one by one to ensure that they cannot be easily pulled out. Not satisfying this requirement may lead to loose connection and missing wires. After the connection is completed, be careful not to apply wire tension (twisting force) directly to the point of contact between the conductive part of the terminal block and the wire. Applying such wire tension may lead to loose connection and power loss. When opening the spring, do not apply excessive force. Doing so may cause damage to the housing.

Fabricating the wire insulator The stripped length of the wire insulator should be 5 mm to 6 mm. Set the appropriate length based on the wire type and fabrication condition. AWG 28 to 14 stranded or solid wire can be connected to CN25. Wire that has a thick insulator and does not fit into the CN25 wire insertion hole cannot be used.

Twist the core wires lightly and straighten them as follows.

Inserting wire Insert one wire per wire insertion hole (round hole) of CN25.

1. Insert a screwdriver diagonally into the operation slot (square hole).

2. Insert the screwdriver fully while adjusting the angle to the upright position. If performed correctly, the screwdriver will hold this position even when released.

3. Insert the properly exposed wire into the wire insertion hole. When doing so, run the wire along the edge of the round hole to insert it smoothly.

4. Insert the wire until it touches the back of the hole, and remove the screwdriver while holding the wire.

5. To confirm, pull the wire lightly. Do not pull harder than necessary. In addition, confirm that the core wires do not fray and stick out. The wire can be removed by inserting a screwdriver into the operation slot.

Even if multiple drive units and servo amplifiers are connected to one converter unit, calculate the power supply capacity from the capacity of the converter unit. If the total value of the output wattage of the servo motors driven by the drive units and servo amplifiers connected to the converter unit is smaller than the converter capacity, the power supply capacity will be smaller than the values in the table. Because 2 to 2.5 times the instantaneous power is required during servo motor acceleration, use a power supply that can secure a voltage within the permissible voltage fluctuation of the main circuit power supply terminals (L1/L2/L3) of the converter unit. The power supply capacity will vary according to the power impedance. The actual amount of generated heat depends on the frequency of use during operation and will be within the range of "At rated output" and "At servo-off". For the design of an enclosed type cabinet, use the values in the tables in consideration for the harshest conditions with regard to the environment and operation pattern.

Heat dissipation area for enclosed type cabinet For the heat dissipation area of the drive unit/servo amplifier, refer to the drive unit/servo amplifier user's manual and instruction manual. The enclosed type cabinet (hereafter called the cabinet) that stores the converter unit should be designed to ensure that its internal temperature rise is within +10 C at an ambient temperature of 40 C. Calculate the necessary heat dissipation area of the cabinet with the equation below (10.1) while allowing a margin of approximately 5 C for a maximum ambient temperature of 55 C.

A: Heat dissipation area [m2] P: Loss generated in the cabinet [W] T: Difference between internal and ambient temperatures [C] K: Heat dissipation coefficient [5 to 6] When calculating the heat dissipation area with the equation (10.1), assume that P is the sum of all losses generated in the cabinet. Refer to the following for details about the heat generated by the converter unit. Page 67 Amount of heat generated by converter unit "A" indicates the effective area for heat dissipation, but if the cabinet is directly installed on an insulated wall, that extra amount must be added to the cabinet's surface area. The required heat dissipation area will vary with the conditions in the cabinet. If convection in the cabinet is poor and heat builds up, effective heat dissipation will not be possible. Therefore, arrangement of the equipment in the cabinet and the use of a cooling fan should be considered. The following page contains information on the required heat dissipation area (estimated) of converter unit cabinets when operating the converter unit at a rated load in ambient temperatures of 40 C. Page 67 Amount of heat generated by converter unit

When air flows along the outer wall of the cabinet, effective heat exchange is possible, because the temperature slope inside and outside the cabinet is steeper.

6.3 Inrush currents at power-on of main circuit and control circuit

A molded-case circuit breaker and magnetic contactor may fail or malfunction due to an inrush current flowing through the converter units power lines (input lines) at power-on. Therefore, use products with the specifications described on the following page. Page 93 Molded-case circuit breakers, fuses, magnetic contactors When circuit protectors are used, it is recommended that the inertia delay type, which is not tripped by an inrush current, be used.

200 V class The following shows the inrush currents (reference data) that will flow when 240 V AC is applied with a wiring length of 1 m.

7 PROTECTION COORDINATION MODE DISABLED (STANDALONE DRIVE)

Precautions Do not apply power to the main circuit power supply terminals (L1/L2/L3) of the servo amplifier. Doing so will cause the

servo amplifier and converter unit to malfunction. Connect the polarities of the DC power supply between the converter unit and the servo amplifier correctly. Connecting

them incorrectly will cause the converter unit and servo amplifier to malfunction. Only the MR-J4 series can be used with the protection coordination mode disabled (standalone drive).

When using a servo amplifier other than a drive unit in combination with the converter unit, set the rotary switch for converter setting (SW1) of the converter unit to "8" to disable protection coordination mode.

The regenerative capacity cannot be improved by connecting two or more converter units in a row. Two or more converter units cannot be connected to the same DC power supply line.

When using a servo amplifier and converter unit in combination, set the parameters of the servo amplifier to enable EM1 (Forced stop 1).

In this configuration, only the STO function is supported. The forced stop deceleration function cannot be used.

When using the converter unit, set the parameters of the servo amplifier.

In this chapter, the connection between the MR-CV_ power regeneration converter unit and the servo amplifier is explained using the MR-J4-_B_ servo amplifier as an example.

10 OPTIONS AND PERIPHERAL EQUIPMENT Precautions

HIV wires are recommended to wire the converter unit, options, and peripheral equipment. Therefore, the recommended wire sizes may differ from those used for the previous generation converter units.

To prevent an electric shock or a fire, correctly wire options and peripheral equipment, etc. in the correct combination.

10.1 Cables/connector sets

The indicated IP rating is the cable and connector's protection against ingress of dust and water when the cable and connector are connected to a converter unit. If the IP ratings of the cables, connectors, and converter units differ, the overall IP rating is determined by the lowest IP rating of all the components.

Purchase the cable and connector options indicated in this section for the MR-CV_ power regeneration converter unit. If using cables other than the cables described in this manual, comply with the standards and directives applicable to each country. For example, NFPA 79 in North America demands the use of a listed, certified product that has a thermoset insulator and is compliant with the NEC standard RHH, RHW, RHW-2, XHH, XHHW, or XHHW-2. For details on the bus bar, refer to the drive unit/servo amplifier user's manual and instruction manual.

Combinations of connector sets For the options used to connect to the drive unit, refer to the drive unit manual.

10.5 Noise reduction techniques Noises are classified into external noises, which enter the converter unit/drive unit to cause it to malfunction, and those radiated by the converter unit/drive unit to cause peripheral equipment to malfunction. Because the converter unit/drive unit is an electronic device that handles small signals, the following general noise reduction techniques are required. The drive unit can also be a source of noise as its outputs are chopped by high carrier frequencies. If peripheral equipment malfunctions due to noise produced by the servo amplifier, take measures to reduce the noise. The reduction techniques will vary slightly with the routes of noise transmission.

Noise reduction techniques General reduction techniques Avoid bundling power lines (input/output lines) and signal cables together or running them in parallel to each other.

Separate the power lines from the signal cables. Use a shielded twisted pair cable for connection with the encoder and for control signal transmission, and connect the

external conductor of the cable to the SD terminal. For grounding, refer to the following. Page 63 Grounding

Reduction techniques for external noises that cause the converter unit/drive unit to malfunction

If noise sources (such as a magnetic contactor, an electromagnetic brake, and many relays) are generating a large amount of noise near the converter unit/drive unit and the converter unit/drive unit may malfunction, the following countermeasures are required. Provide surge killers on the noise sources to suppress noise. Attach data line filters to the signal cables. Ground the shields of the encoder connecting cable and the control signal cables with cable clamp fittings. Although a surge absorber is built into the converter unit, to protect the converter unit/drive unit and other equipment

against large exogenous noise and lightning surge, attaching a varistor to the power input section of the equipment is recommended.

Techniques for noises radiated by the converter unit/drive unit that cause peripheral equipment to malfunction

Noises produced by the converter unit/drive unit are classified into those radiated from the cables connected to the converter unit/drive unit and its main circuits (input/output), those induced electromagnetically or statically by the signal cables of the peripheral equipment located near the main circuit cables, and those transmitted through the power supply cables.

Noise reduction products For the noise reduction products to connect to a drive unit, refer to the manual and instruction manual of each drive unit.

Line noise filter (FR-BLF) This filter is effective in suppressing noise radiated from the power supply of the converter unit and output side of the drive unit and also in suppressing high-frequency leakage current (0-phase current). It is especially effective for noise between 0.5 MHz and 5 MHz band. Connection diagram Pass the three-phase wires through four line noise filters. When using a line noise filter for the power supply line, passing it through together with the grounding wire reduces the filter effect. Wire the grounding wire separately from the power supply wire.

Suppression techniques

(1), (2), (3) A malfunction due to noise transmitted through the air may occur in devices which handle weak signals and are susceptible to noise, such as measuring instruments, receivers and sensors. In addition, a malfunction may also occur when their signal cables are stored in a cabinet together with a converter unit/drive unit or when the signal cables run near it. Take the following measures to prevent a malfunction: Provide maximum clearance between easily affected devices and the converter unit/drive unit. Provide maximum clearance between easily affected signal cables and the I/O cables of the converter unit/drive unit. Avoid bundling power lines (input/output lines of the converter unit/drive unit) and signal cables together or running them in

parallel to each other. Insert a line noise filter to the I/O cables or a radio noise filter on the input line to reduce radiated noise from the cables. Use shielded wires for the signal and power lines, or put the lines in separate metal conduits.

(4), (5), (6) When power cables and signal cables are laid side by side or bundled together, electromagnetic and static induction noise is transmitted to the signal cables, causing malfunctions. Take the following precautions to protect the signal cables against noise. Provide maximum clearance between easily affected devices and the converter unit/drive unit. Provide maximum clearance between easily affected signal cables and the I/O cables of the converter unit/drive unit. Avoid bundling power lines (input/output lines of the converter unit/drive unit) and signal cables together or running them in

parallel to each other. Use shielded wires for the signal and power lines, or put the lines in separate metal conduits.

(7) When the power supply of peripheral equipment is connected to the power supply of the converter unit/drive unit, noise produced by the converter unit/drive unit may be transmitted back through the power supply cable, and the equipment may malfunction. The following techniques are required. Install the radio noise filter (FR-BIF(-H)) on the power lines (input lines) of the converter unit/drive unit. Install the line noise filter (FR-BSF01/FR-BLF) on the power lines of the converter unit/drive unit.

(8) If the grounding wires of the peripheral equipment and the converter unit/drive unit make a closed loop circuit, leakage current may flow through, causing the equipment to malfunction. In this case, the malfunction may be prevented by disconnecting the grounding wires from the equipment.

11 COMPLIANCE WITH GLOBAL STANDARDS This chapter describes the converter unit and drive units as servo amplifiers.

11.1 Compliance with global standards Refer to the following manual for information about compliance with global standards. MR-CV_ Instructions and Cautions for Safe Use of AC Servos (IB(NA)-0300228)

11.2 Compliance with China Compulsory Certification (CCC)

Introduction Some products are required to comply with China Compulsory Certification (hereinafter referred to as CCC) if exported, distributed, or sold to China. An outline of CCC is explained in this section. Mitsubishi Electric servo products are not subject to CCC.

Outline of CCC CCC is a system for product certification that has been in effect in China since August 2003, the purpose of which is to protect consumers and ensure safety domestically in China. The certification system currently has five types of certification: safety, electromagnetic compatibility (EMC), safety + EMC, fire-fighting equipment, and wireless LAN. Products subject to the certification are allowed to be exported, distributed, or sold to China only if they are certified by this system. Products that have received certification proving compliance with the relevant technical standards (or products declared by the manufacturer as being compliant) must carry the specified mark (CCC mark). Many of the technical standards to be applied are GB standards (Chinese national standards), which comply with global standards such as those set forth by the IEC (International Electrotechnical Commission) and CISPR (International Special Committee on Radio Interference).

Judgment 20 product groups divided into 158 categories are specified as the subject products (announcement No. 45, 2014). The following table shows whether the servo products are required to comply with CCC.

*1 Small capacity motors with a capacity of 750 W or lower are included in the catalog of products subject to CCC, but the requirements do not apply to our products for the following reasons: Explosion proof motors and controlled motors (servo motors, stepping motors, etc.) are excluded from the subject small capacity motors.

*2 Mitsubishi Electric option cables use the wires that is not classified into the cable category in the catalog.

11.3 Compliance with the China RoHS directive

Outline TThe China RoHS directive: (Management Methods for Controlling Pollution by Electronic Information Products) came into effect on March 1, 2007. The China RoHS directive was replaced by the following China RoHS directive: (Management Methods for the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products). The succeeding China RoHS directive has been in effect since July 1, 2016. The China RoHS directive restricts the following hazardous substances: six hazardous substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE)) which are also restricted by EU RoHS 2 (directive 2011/65/EU), and other hazardous substances specified by the State (currently no applicable substances).

Status of our products for compliance with the China RoHS directive The following table shows the logo types for the environmental protection use period, and whether the six hazardous substances are contained in our products or not. This table was created based on the standard SJ/T11364.

*1 : Indicates that said hazardous substance contained in all of the homogeneous materials for this part is below the limit requirement of GB/T26572. : Indicates that said hazardous substance contained in at least one of the homogeneous materials for this part is above the limit requirement of GB/T26572.

Difference between the China RoHS directive and the EU RoHS directive The China RoHS directive allows no restriction exemption unlike the EU RoHS directive. Although a product complies with the EU RoHS directive, a hazardous substance in the product may be considered to be above the limit requirement (marked "") in the China RoHS directive. The following shows some restriction exemptions and their examples according to the EU RoHS directive. Lead as an alloying element in steel for machining purposes and in galvanized steel containing up to 0.35 % lead by

weight, lead as an alloying element in aluminum containing up to 0.4 % lead by weight, and copper alloy containing up to 4 % lead by weight, e.g. brass-made insert nuts

Lead in high melting temperature type solders (i.e. lead-based alloys containing 85 % by weight or more lead) Electrical and electronic components (such as piezoelectric sensors) containing lead in glass or ceramic materials, but not

including the dielectric ceramics used in capacitors Electrical and electronic components containing lead in a glass or ceramic matrix compound, e.g. chip resistors
