1. SUMMARY
The MR-J2S renewal tool is a tool to replace the presently used MR-J2S servo amplifier with the MR-J4

1.2 Features
• It is possible to operate the exiting MR-J2S servo motor with the MR-J4 servo amplifier.
• Wiring work can be shortened because the existing cables can be connected as they are. (except for some
models)
• The renewal kit can be mounted using the existing mounting holes.
• The existing space can be effectively used by adopting the sliding mechanism for the renewal kit. (For
some models)
• By utilizing the renewal tool, it is possible to replace by proceeding in stages from primary replacement to
secondary replacement.
Primary replacement: Replace the servo amplifier only.
Secondary replacement: Replace the servo motor after replacement of the servo amplifier.
Simultaneous replacement: Replace the servo amplifier and the servo motor simultaneously.
* It is not possible to replace the servo motor only.
* A separate 24 V DC power supply (current capacity: 80 mA or more) for the interface is required when
the internal 24 V DC power supply for the interface is used for the MR-J2S servo amplifier. Must be
provided by the customer. (Not included with the renewal tool.)
