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.
For details, refer to MR-J4-_B-RJ020 Series Servo Amplifier Technical Reference Material issued by Mitsubishi Electric
Corporation.
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.
For details, refer to MR-J4-_B-RJ020 Series Servo Amplifier Technical Reference Material issued by Mitsubishi Electric
Corporation.
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))
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.
For details, refer to MR-J4-_B-RJ020 Series Servo Amplifier Technical Reference Material issued by Mitsubishi Electric
Corporation.
5. Unnecessary if electromagnetic brakes are not installed.
6. Required for the HG-JR22K1M motor only. There is no cooling fan for the HG-JR11K1M or HG-JR15K1M motor. Because the
existing wiring becomes unnecessary, insulate as needed.
