[Appendix 2] Introduction to Renewal Tool
5. RENEWAL TOOL CONNECTION DIAGRAM
These diagrams are the connection diagrams for wiring the servo amplifier and servo motor when using the
renewal tool.
* Since a terminal block is not included with the renewal tool (mounting attachment) for 400 V, refer to MR-J4
Servo Amplifier Instruction Manual for the detailed connection.

Note 1. When using the regenerative option, make sure to remove the wiring or the short-circuit bar across P (+) and D, connect with
the wiring between the renewal kit and the servo amplifier, and mount the regenerative option between P and C.
When using a built-in regenerative resistor, make sure to connect the wiring or the short-circuit bar across P (+) and D. For
SC-J2S(CP)J4KT3K, insulate the wiring between the renewal kit and the servo amplifier. Ensure the connection destinations
are correct. The servo amplifier may malfunction if the connection destinations are incorrect.
2. The N terminal of TE2 is limited to SC-J2S(CP)J4KT1K and 3K. There is no D terminal wiring for SC-J2S(CP)J4KT3K.
3. Required only when the internal power supply (24 V DC) for the I/F is used in the existing MR-J2S 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))
