Note 1. For the MR-RB137. For the MR-RB137, three units are used as one set

Note 1. This is for MR-RB137. For the MR-RB137, 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 7.3" 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.
Always connect the magnetic contactor wiring connector to CNP1 of the
resistance regeneration converter unit. If the connector is not connected,

Keep the wiring connector for the magnetic contactor connected to CNP1

amplifier instruction manual".
Instruction Manual (Vol. 3)".
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. Be sure to use a magnetic contactor with an operation delay time of 80
ms or less. The operation delay time is the time interval between current
being applied to the coil until closure of contacts.
The bus voltage decreases depending on the main circuit voltage and
operation pattern, which may cause the forced stop deceleration to shift to
7. 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 emergency stop and such conditions. Ensure the safety
in the entire system.
the dynamic brake deceleration. When dynamic brake deceleration is not
required, slow the time to turn off the magnetic contactor.
6. To prevent an unexpected restart of the drive unit, configure a circuit to
turn off EM2 in the drive unit when the main circuit power is turned off.
7. 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 and for wiring of the
external dynamic brake, refer to "MR-CV_/MR-CR55K_/MR-J4-DU_(-RJ)
instruction manual".
8. For the encoder cable, use of the option cable is recommended. For
selecting cables, refer to "Servo Motor Instruction Manual (Vol. 3)".
9. This diagram shows sink I/O interface. For source I/O interface, refer to
"MR-CV_/MR-CR55K_/MR-J4-DU_(-RJ) instruction manual".
10. Install an overcurrent protection device (molded-case circuit breaker or
fuse) to protect the branch circuit. (Refer to section 7.3.)
11. When not using the STO function, attach the short-circuit connector
supplied with the drive unit.
12. 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.
13. For connecting servo motor power wires, refer to "Servo Motor Instruction
Manual (Vol. 3)".
14. 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.
