１.３ 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 existi
ng cables can be connected as they are.
• 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 replac
e 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.
Package 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 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.)
