Note 1. When using the regenerative option, make sure to remove the wiring for the regenerative resistor built in to 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-J2SJ4KT7K 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.
