7 POSITIONING MODULE REPLACEMENT
7 - 41
(3) Supported servo amplifier
(a) For continuous use of a servo amplifier connected with the existing AD75M
The following table shows whether or not the existing servo amplifier can be continuously used with
positioning modules replaced.
Point
(1) Selecting suitable products to replace the existing servo amplifier
When replacing the existing servo amplifier, select a positioning module in the following
combinations.
Additionally, the servo motor needs to be replaced.
• Positioning module: QD77MS + servo amplifier: MR-J3-B
• Positioning module: QD77MS + servo amplifier: MR-J4-B
(2) Selecting suitable products to replace the existing servo amplifier without servo motor
replacement
When replacing the existing servo amplifier alone without servo motor replacement, select a
module in the following combination.
• Positioning module: QD75M
For replacing servo amplifiers and servo motors, data such as positioning parameters and positioning
data need to be changed.
When replacing them, contact the department in charge of Mitsubishi electric servo products.
For replacing the MR-J2S-B, refer to "Transition from MELSERVO-J2-Super/J2M Series to J4 Series
Handbook" (L(NA)03093).
