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-J2SBJ4KT3K, 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-J2SBJ4KT1K and 3K. There is no D terminal wiring for SC-J2SBJ4KT3K.
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-_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))
