Part 2: Review on Replacement of MR-J2S-_A_ with MR-J4-_A_
(2) Separate repair of servo amplifier/servo motor
After replacement, an HC/HA motor can be driven by MR-J4-_A_. Refer to "Part 7: Common
Reference Material" for target motors.
When an HC-_FS/HA-_FS motor is driven by MR-J4-_A_, it is necessary to set [Pr. PC22].
Refer to Part 7 Section 4.
Use the renewal tool when replacing a servo amplifier with MR-J4-_A_ without replacing the currently
used servo motor and existing cables. (Refer to "[Appendix 2] Introduction to Renewal Tool".)
The parameters of the existing system can be transferred with the parameter converter function of MR
Configurator2. (Refer to "Part 7: Common Reference Material".)
[Existing system]
POINT
An HG motor cannot be driven by MR-J2S-_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-_FS/HA-_FS 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 8:
Replacement of Motor".)
