Cause
1.
An excessive speed or acceleration was
detected due to an oscillation or other factors.
2.
The load-side encoder has malfunctioned.
3.
There is a problem with the surrounding
environment.
[AL. 072.2_Load-side encoder data update error]
Cause
1.

Check/action method
Decrease the control gain, then check the repeatability. If the error does not
repeat, use the encoder with a lower gain.
Replace the load-side encoder.
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.
