[Appendix 2] Introduction to Renewal Tool
Appendix 2-78
5.7 SC-J2SBJ4KT7K
(1) Primary replacement (when replacing the servo amplifier only)
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.
2. There is no conversion terminal block in the SC-J2SBJ4KT7K renewal kit. Directly connect to the MR-J4 servo amplifier.
3. Required only when the internal power supply (24 V DC) for the I/F is used in the existing MR-J2S-_B 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. (Electric wire colors: Red (+ side); white (- side))
