[Appendix 2] Introduction to Renewal Tool
5.6 SC-J2SBJ4KT5K
(1) Primary replacement (when replacing the servo amplifier only)
For 3-phase 200 V connection
MC
NFB
3-phase
200 to 230VAC
Note 1. When using the regenerative option, make sure to remove the short-circuit bar 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.
2. There is no conversion terminal block in the SC-J2SBJ4KT5K 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))
