2. When using a power factor improving DC reactor, remove the
short-circuit bar between P1 and P2.
3. Use a step-down transformer when the coil voltage of the
magnetic contactor is 200 V class.
4. Use an MR-J2HBUS_M_ SSCNET cable as a protection
coordination cable.
5. Use an external dynamic brake to this servo amplifier. Without an
external dynamic brake, the servo motor keeps running at an
emergency stop in a free run state, leading to an accident. Take
as many safety measures as possible in the system.
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. 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 section 8.6 for details.
3. A step-down transformer is required when the coil voltage of the magnetic contactor is 200 V class.
4. Connect the magnetic contactor wiring connector to CNP1 of the converter unit. If the connector is not connected, an electric shock may occur.
5. For specifications of the cooling fan power supply, refer to "Servo Motor Instruction Manual (Vol. 3)".
6. 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. The bus voltage decreases depending on the main circuit voltage and operation pattern, which may cause the forced stop deceleration to
shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn off the magnetic contactor.
7. 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.
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 section "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 5.3.)
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.
17. The converter unit and the drive unit can be connected to the control circuit power supply (L11/L21) by daisy chain. Refer to section 5.2 for the
wire size and the selection of the overcurrent protection device.
