Mitsubishi General-Purpose AC Servo
Renewal Tool

Support from MR-J2 Super Series to MR-J4 Series
Replacement.
Supported models• MR-J2S-A(1) (0.1 to 37kW)• MR-J2S-A4 (0.6 to 55kW)• MR-J2S-B(1) (0.1 to 37kW)• MR-J2S-B4 (0.6 to 55kW)• MR-J2S-CP (0.1 to 7kW)

MR-J2S

Features Complete upgrades in a short time by using existing wiring and mounting holes.
 The AC servo can be replaced independently, without replacing the host controller or SSCNET cable.
 Replacement of a single axis in a multi-axis system is possible.
 The MR-J2S motor can be controlled with the MR-J4 servo amplifier.

Precautions for Replacement
 MR-J2 Series replacements are not supported.
 The initialization time after power ON differs for the MR-J2S servo amplifier and MR-J4 servo amplifier, so it may benecessary to change the program in existing system.
(* Pay special attention to the magnetic brake release time for the vertical axis. The vertical axis could drop.) The outline dimensions will be larger than the existing MR-J2S servo amplifier when using this renewal tool.
Refer to the outline dimensions on the back page for details on the dimensions. Always confirm that there issufficient space before selecting this tool.
 When making a secondary package replacement, the monitor output value (motor rotation speed) will differ from theexisting amplifier because of a difference in the motor’s maximum rotation speed.
The program must be changed when using the monitor output with existing system.
 Note that even when this renewal tool is used, some MR-J2S servo functions may not be 100% compatible.
 Depending on the situation, it may be necessary to change the existing wiring or add a noise filter, etc. as a noise
countermeasure when using the servo system controller and positioning module (model: A1SD75P, etc.).
 Refer to the Guide for Replacing MR-J2S/J2M Series with J4 Series “L (NA) 03093” issued by Mitsubishi Electric,
and the “Guide for Replacing MELSERVO-J2S Series using the MR-J2S Renewal Tool (X903120701)” available on
the Mitsubishi Electric System & Service web site for replacing the MR-J2S Series with the MR-J4 Series.

Replacing MELSERVO-J2S Series with MELSERVO-J4 Series
The MR-J2S renewal tool is used to replace an existing MR-J2S Series amplifier with the MR-J4 Series amplifier.
The renewal kit provides compatibility to existing installation dimensions and terminal blocks.
The conversion cable is interchangeable allowing existing cables to be used with the replacement models.

Use existing mounting holes to upgrade in a short time!

Refer to the Mitsubishi Electric System & Service web site for motors with reduction gears and models not listed above.
When the gain of the existing servo amplifier is extremely high, the characteristics may differ slightly if a primary replacement is made. Always set the gain again.
The replacement servo amplifier, SSCNET conversion unit and renewal kit are common for the primary, secondary and package replacements.
Purchase from Mitsubishi Electric Corp.
When making a primary replacement, the amplifier software version may differ according to the supported motor. Consult with Mitsubishi Electric Corp. when placing an order.
When replacing the motor, the motor’s moment of inertia will differ from the original motor. Pay attention to the load moment of inertia rate. The operation pattern may need to be reviewed depending on the existing system.
Refer to the “Guide for Replacing MELSERVO-J2S/J2M Series with J4 Series L (NA) 03092” issued by Mitsubishi Electric for details on the motor specifications.
*7. Note that the entire length of the motor will be shorter, so the motor connector may interfere with the system side.
*8. When replacing the motor with brakes with secondary or package replacement, a magnetic brake cable must be newly connected. Use the Mitsubishi Electric System & Service motor magnetic brake cable (SC-BKC1CBLM-L
or SC-BKC1CBLM-H).
*9. When replacing the motor, the flange dimensions and shaft dimensions will not be interchangeable. The mounting section and the coupling section with the servo motor shaft, such as the coupling pulley must be changed.
Refer to the “Guide for Replacing MELSERVO-J2S/J2M Series with J4 Series L (NA) 03092” issued by Mitsubishi Electric for details on the motor specifications.
*10. When replacing the motor, the existing power cable’s crimp terminal must be changed. Refer to the “Guide for Replacing MELSERVO-J2S/J2M Series with J4 Series L (NA) 03092” issued by Mitsubishi Electric for details on the
motor specifications.
*11. When replacing the motor, the new motor will not have a cooling fan. The existing wiring will no longer be required, so always insulate it.
*12. If the servo amplifier must be replaced again for the secondary replacement, a package replacement is recommended.
*13. The renewal kit cannot be used with the secondary replacement or package replacement, as the servo amplifier’s dimensions could vary greatly because of a change in servo amplifier capacity. Use the amplifier conversion
cable set in this case.
*14. A new encoder cable must be connected when replacing the motor. Contact Mitsubishi Electric System & Service to purchase a new cable.
*15. Use this amplifier in combination with the converter unit MR-CR55K.
*16. Use this amplifier in combination with the converter unit MR-CR55k4.
*17. The renewal kit is not required for this combination. Purchase only the amplifier conversion cable if necessary.
*18. Either “A1” or “A2” is indicated at  in the model. (A1 is connected to load side, and A2 is connected to opposite load side.)
