Part 2: Review on Replacement of MR-J3-_A_ with MR-J4-_A_
2 - 3
(2) Separate repair of servo amplifiers and servo motors
POINT
An HG motor cannot be driven by MR-J3-_A_. When a servo motor is replaced
with an HG motor, servo amplifier also needs to be replaced with MR-J4-_A_
simultaneously.
When an "HC-_P motor" shown below is used, "simultaneous replacement with
MR-J4-_A_ and an HG motor" is recommended. When an HG motor is adopted,
the capacity of the servo amplifier needs to be changed. (Consider replacement,
referring to "torque characteristics" described in "Part 7: Replacement of
Motor".)
The low inertia "HG-JR motor" is recommended for the replacement of "HC-LP
motor".
To use a servo motor other than the motors listed in following table, check the
compatibility with the equipment because the motor inertia, etc. is different.

Replacement of servo amplifier Replacement of servo motor
Replacing the system allows the J3 series servo motors to drive in
MR-J4-_A_. Refer to "Part 6: Common Reference Material" for
target motors. The HG motor cannot be driven by MR-J3-_A_. When a servo
motor is replaced with an HG motor, servo amplifier also needs to
be replaced with MR-J4-_A_ simultaneously.
