1. SERVO MOTOR REPLACEMENT

1.1 Servo Motor Substitute Model and Compatibility

POINT
For details about the compatibility of servo motor dimensions, reducer
specifications, moment of inertia, connector specifications, and torque
characteristics, refer to "Chapter 2 COMPARISON OF SERVO MOTOR
SPECIFICATIONS".
The symbols in the table mean as follows.
(B): With brake
(4): 400 V specifications
(H): Foot-mounting
When an "HA-LP motor" shown below is used, "simultaneous replacement with
MR-J4-_A_/MR-J4-_B_ 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 "Part 7: Replacement of Motor section 2.7 Comparison
of Servo Motor Torque Characteristics".)
