Procedure of replacing a servo motor with battery-less absolute
position encoder
To replace a servo motor with battery-less absolute position encoder, use the following procedure.
1.
Replacing the servo motor
Turn off the power and replace the servo motor.
2.
Canceling [AL. 01A Servo motor combination error]
After the power is turned on, [AL. 01A.5 Servo motor combination error 3] occurs.
After setting [Pr. PA03.1 Servo motor replacement preparation] to "1" (enabled), cycle the power and then deactivate [AL.
01A.5].
3.
Homing
Because the absolute position data is erased during servo motor replacement, perform homing again before operation.

The value of servo motor (machine) edge pulse unit is acquired from the servo amplifier of the target
axis and displayed.
The value of command pulse unit is acquired from the servo amplifier of the target axis and displayed.
[G] [WG]: The pulse data of the servo motor (load) side position within one-revolution is acquired from
the servo amplifier of the target axis and displayed.
[A]: The command pulse data of the position within one-revolution is acquired from the servo amplifier of
the target axis and displayed.
The multi-revolution counter travel distance from the absolute home position is acquired from the servo
amplifier of the target axis and displayed.
[G] [WG]: The pulse data of the servo motor (load) side home position within one-revolution is acquired
from the servo amplifier of the target axis and displayed.
[A]: The command pulse data of the home position within one-revolution is acquired from the servo
amplifier of the target axis and displayed.
The multi-revolution counter value of the absolute home position is acquired from the servo amplifier of
the target axis and displayed.
