Make sure to remove the power supply between P and D.
必ずP- D間の電線を外してください 。
Note 1. When using the regenerative option, make sure to remove the wiring between P+ and D, connect with the wiring between the
renewal kit and the servo amplifier, and mount the regenerative option between P+ and C. Ensure the connection destinations
are correct. The servo amplifier may malfunction if the connection destinations are incorrect.
For details, refer to MR-J4-_A Series Servo Amplifier Technical Reference Material issued by Mitsubishi Electric Corporation.
2. There is no conversion terminal block in the SC-J2SJ4KT5K renewal kit. Directly connect to the MR-J4 servo amplifier.
For details, refer to MR-J4-_A Series Servo Amplifier Technical Reference Material issued by Mitsubishi Electric Corporation.
3. Unnecessary if electromagnetic brakes are not installed.
4. Required only when the internal power supply (24 V DC) for the I/F is used in the existing MR-J2S-_A_ servo amplifier. Not
included with the renewal tool. Note that a separate 24 V DC power supply (current capacity: 80 mA or more) is required when
replacing.
When connecting the 24 V DC power supply, use the "24 V DC power supply connection cable (model: SC-J2SJ4CTPWC5M)"
included in the package.
