Note 1. For the MR-RB138-4. For the MR-RB138-4, three units are used as one
set (permissible wattage: 3900W).
Note 1. This is for MR-RB13V-4. For the MR-RB13V-4, three units are used as
one set (permissible regenerative power: 3900 W).
2.
When using the Power factor improving DC reactor, disconnect the short
bar across P1 and P2.
2.
P1 and P2 are connected by default. When using the power factor
improving DC reactor, connect P1 and P2 after removing the short bar
across them. Refer to "Part: 8 section 7.4" for details.
3.
Make up a sequence that will concurrently turn off the Emergency stop
(EMG) of the drive unit and the Forced stop (EM1) of the converter unit,
and shut off the main circuit power supply by the external sequence.
3. A step-down transformer is required when the coil voltage of the magnetic
contactor is 200 V class.
4. Stepdown transformer is required for coil voltage of magnetic contactor
more than 200V class.
4. Always connect the magnetic contactor wiring connector to CNP1 of the
converter unit. If the connector is not connected, an electric shock may
occur.
5. Keep the wiring connector for the magnetic contactor connected to CNP1
of the converter unit. Unconnected status may cause an electric shock.
5. For specifications of the cooling fan power supply, refer to "Servo Motor
Instruction Manual (Vol. 3)".
6.
For specifications of cooling fan power supply, refer to "MR-J3-_A_ Servo
amplifier instruction manual".
6.
Use a magnetic contactor with an operation delay time (interval between

turn off EM2 in the drive unit when the main circuit power is turned off.
8. Use an external dynamic brake for the drive unit. Failure to do so will
cause an accident because the servo motor does not stop immediately but
coasts at an alarm occurrence for which the servo motor does not
decelerate to stop. Ensure the safety in the entire equipment. For alarms
for which the servo motor does not decelerate to stop, refer to chapter 6.
For wiring of the external dynamic brake, refer to "MR-CV_/MR-
CR55K_/MR-J4-DU_(-RJ) instruction manual".
9. For the encoder cable, use of the option cable is recommended. For
selecting cables, refer to "Servo Motor Instruction Manual (Vol. 3)".
10. This diagram shows sink I/O interface. For source I/O interface, refer to
"MR-CV_/MR-CR55K_/MR-J4-DU_(-RJ) instruction manual".
11. Install an overcurrent protection device (molded-case circuit breaker or
fuse) to protect the branch circuit. (Refer to section 7.3.)
12. When not using the STO function, attach the short-circuit connector
supplied with the drive unit.
13. Do not connect the servo motor of a wrong axis to U, V, W, or CN2 of the
drive unit. Otherwise, a malfunction may occur.
14. For connecting servo motor power wires, refer to "Servo Motor Instruction
Manual (Vol. 3)".
15. For the MR-J4-DU30K_4(-RJ) and MR-J4-DU37K_4(-RJ), the terminal
block is TE2.
16. The external dynamic brake cannot be used for compliance with SEMI-F47
standard. Do not assign DB. Failure to do so will cause the drive unit to
become servo-off when an instantaneous power failure occurs.
