1.1 Description

This Instruction Manual describes MR-J4-DU_B4-RJ100 drive units and MR-CV55K4_ power regeneration converter units

compatible with parallel drive systems.

Parallel drive systems drive a servo motor with multiple MR-J4-DU_B4-RJ100 drive units and MR-CV55K4_ power

regeneration converter units connected. The encoder cables are wired by the daisy chain method. Delivering the encoder

information to all servo amplifiers, from encoder master servo amplifiers to encoder slave servo amplifiers, ensures reduced

wiring. A encoder distribution unit is not required.

The following shows a system that drives a servo motor with four MR-J4-DU_B4-RJ100 drive units and four MR-CV55K4_

power regeneration converter units connected. For the number of drive units required to be connected to one servo motor,

refer to the following. Page 13 Combinations of power regeneration converter units, drive units, and servo motors

WARNING

• Insulate the connections of the power supply terminals. Otherwise, an electric shock may occur.

CAUTION

• Be sure to connect a magnetic contactor between the power supply and the main circuit power supply (L1/L2/L3) of the power regeneration converter unit, in order to configure a circuit that shuts off the power supply by the power regeneration converter unit. If a magnetic contactor is not connected, continuous flow of a large current may cause a fire when the power regeneration converter unit or the drive unit malfunctions.

• Use ALM (Malfunction) to shut the power off. Not doing so may cause a fire when the power regeneration converter unit malfunctions and causes the AC reactor to overheat.

• The power regeneration converter unit has a built-in surge absorber (varistor) to reduce exogenous noise and to suppress lightning surge. Exogenous noise or lightning surge deteriorates the varistor characteristics, and the varistor may be damaged. To prevent a fire, use a molded-case circuit breaker or fuse for the input power supply.

• Check the power regeneration converter unit model, and then input proper voltage to the power regeneration converter unit power supply. If input voltage exceeds the upper limit, the power regeneration converter unit and the drive unit will break down.

For drive units, EM2 has the same function as EM1 in the torque control mode.

Even if alarm has occurred, do not switch off the control circuit power supply. When the control circuit power

supply is shut off, an optical module does not operate, and optical transmission of SSCNET III/H

communication is interrupted. Therefore, the next servo amplifiers and drive units show "AA" on the display

and shut off the base circuit, stopping the servo motor with the dynamic brake.

For the magnetic contactor control connector (CN23), refer to section 3.3 in "MR-CV_/MR-CR55K_/MR-J4-

DU_(-RJ) Instruction Manual".

If the control axis No. is not be set correctly, or an SSCNET III cable is not be connected, the relay may switch

on and off repeatedly. Check the control axis No. setting and SSCNET III cable connection.

3.1 Connection example of power circuit

*1 To prevent an unexpected restart of the drive unit, configure a circuit to turn off EM2 (Forced stop 2) in the drive unit when the main

circuit power is turned off.

*2 Always match the phases of the power supply connected to L11 and L21 on the power regeneration converter unit and the drive unit with

the phases connected to L1 and L2. Otherwise, the drive unit and the power regeneration converter unit may malfunction.

*3 Always supply power to the cooling fan terminal. For specifications of the cooling fan power supply and how to detect a failure, refer to

"Servo Motor Instruction Manual (Vol. 3)".

*4 Connect the grounding wire from the servo motor to the protective earth (PE) terminal of the drive unit. Put the grounding wires of the

drive unit and the power regeneration converter unit together into one on the protective earth (PE) terminal of the cabinet, and then connect to the ground. Connect the grounding wire of the servo motor to only the drive unit of the encoder master servo amplifier. If the grounding wire of the servo motor is connected to two or more drive units, the circulating current may pass through the grounding wire depending on wiring conditions. When connecting grounding wires to two or more drive units, be sure to twist the wires of the drive unit power outputs (U/V/W).

*5 Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80

ms or less.

*6 For absolute position detection systems, connect an optional battery to only the drive unit of the encoder master servo amplifier. Do not

connect the optional battery to the drive units of the encoder slave servo amplifiers.

*7 Use an external dynamic brake (option) together. Failure to do so will cause an accident, such as machine collision because the servo

motor does not stop immediately but coasts at emergency stop. For wiring of the dynamic brake, refer to the following. Page 69 External dynamic brake

*8 Encoder signals are distributed to all the drive units in the system via each drive unit. *9 This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3 in MR-J4-_B_(-RJ) Servo Amplifier Instruction

encoder slave servo amplifiers. *12 When not using the STO function, always attach the short-circuit connector supplied with the drive unit. *13 If the wire size used for the branch circuit is smaller than that used for L1, L2, and L3, install an overcurrent protection device (molded-

case circuit breaker, fuse, or others) to protect the circuit. *14 Even if an AC reactor is installed on the power regeneration converter unit, the functions operate normally. *15 A step-down transformer is required when the coil voltage of the magnetic contactor is 200 V class. *16 Supply power to all the servo amplifiers (power regeneration converter units and drive units) from the same power source. If power is

supplied from different power sources, a difference may be generated between outputs of the encoder master servo amplifier and that of
