Procedure Of Replacing A Servo Amplifier Without Losing The Absolute Position Data [B] - Mitsubishi Electric MELSERVO-J5 User Manual

Procedure of replacing a servo amplifier without losing the
absolute position data [B]
When using existing parameter settings for a servo amplifier with factory settings, check that the settings of
[Pr. PC92 Servo amplifier replacement data 9] to [Pr. PC95 Servo amplifier replacement data 12] are "0"
before connecting the servo amplifier to the controller. Otherwise, [AL. 01A.6 Servo motor combination error
4] may occur. When [AL. 01A.6] occurs, after changing the setting value of [Pr. PA03.2 Scale measurement
encoder replacement preparation] to "1" (enabled), cycle the power and then deactivate [AL. 01A Servo motor
combination error]. Perform homing again. After connecting the servo amplifier to the controller, servo
parameters will be set automatically.
To replace a servo amplifier that uses a servo motor with a batteryless absolute position encoder for scale measurement due
to a servo amplifier malfunction, use the following procedure.
1.
Servo parameter setting
After the communication between the controller and the servo amplifier is established, set [Pr. PF63.2 Servo amplifier
replacement data save selection] to "1" (enabled). After setting, cycle the power, or reset either the controller or the software
to reflect the setting.
2.
Checking the setting values of the controller
After the communication between the controller and the servo amplifier is established, check that the value is reflected to [Pr.
PC92 Servo amplifier replacement data 9] to [Pr. PC95 Servo amplifier replacement data 12] with the controller.
3.
Replacing the servo amplifier
Turn off the power supply of the servo amplifier and replace it. The absolute position will not be erased. This enables
positioning operation without performing homing again.
