[Appendix 2] Introduction to Renewal Tool
5.4 SC-J2SJ4KT15K, 22K
(1) Primary replacement (when replacing the servo amplifier only)
For 3-phase 200 V connection

200 to
230VAC

(Note 2)
Regenerative
option
Note 1. Make sure to connect between P3 and P4. When using the power factor improving DC reactor, remove the short circuit bar
between P3 and P4 before connection.
2. When using the regenerative option, make sure to 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.
3. 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. (Electric wire colors: Red (+ side); white (- side))
4. When connecting a power regenerative converter (FR-RC-_K) and a brake unit (FR-BU2-_K), connect between P+ and N-.
Make sure to remove the built-in regenerative resistor or the regenerative option.
