[AL. 01A.5_Servo motor combination error 3]
Cause
1.
The servo motor that was connected at the
startup of the absolute position detection
system was changed to a different servo
motor.
2.
At occurrence of [AL. 025 Absolute position
erased], the power was cycled without leaving
the servo motor for 5 s.
3.
The servo motor was replaced.
4.
The servo amplifier has malfunctioned.
5.
The encoder has malfunctioned.
6.
There is a problem with the surrounding
environment.
[AL. 01A.6_Servo motor combination error 4]
Cause
1.
The scale measurement encoder that was
connected at the startup of the absolute
position detection system was changed to a
different scale measurement.
2.
At occurrence of [AL. 025 Absolute position
erased], the power was cycled without leaving
the servo motor for 5 s.
3.
The scale measurement encoder was
replaced.
4.
The servo amplifier has malfunctioned.
5.
The scale measurement encoder has
malfunctioned.
6.
There is a problem with the surrounding
environment.
Check/action method
Check if a servo motor other than the one that was connected at the startup of
the absolute position detection system is connected. If a different servo motor
is connected, reconnect to the servo motor that was connected at the startup
of the absolute position detection system.
After changing the setting value of [Pr. PA03.1 Servo motor replacement
preparation] to "1" (enabled), cycle the power and then deactivate [AL. 01A
Servo motor combination error]. Perform homing again.
After changing the setting value of [Pr. PA03.1] to "1" (enabled), cycle the
power and then deactivate [AL. 01A]. Perform homing again.
Replace the servo amplifier.
Replace the servo motor.
Check the noise, ambient temperature, and other conditions, and implement
appropriate countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.

different scale measurement encoder is connected, reconnect to the scale
measurement encoder that was connected at the startup of the absolute
position detection system.
After changing the setting value of [Pr. PA03.2 Scale measurement encoder
replacement preparation] to "1", cycle the power and then deactivate [AL. 01A
