1. OVERVIEW OF A-MOTION REPLACEMENT
4.2 2): When only Controllers and Servo Amplifiers are Changed
The following shows the procedure for updating a system when only controllers and servo amplifiers are
changed.
* Although HC/HA motors can be used without any change, the encoder resolution of the servo amplifier
becomes 17 bits.
For the applicable servo motors and servo amplifiers, contact your local sales office.
POINT
● When the following HC/HA motors are used, changing the motors with HG motors and
servo amplifiers with MR-J4-_B_ in a batch is recommended.
(To use HG motors, the capacity of servo amplifiers may need to be changed.)
