Error description 231-A910

Error message

A910 CC Speed/noml. value deviation too large %1

Cause of error

- The actual velocity deviates for longer than the permissible duration
(feed axes: machine parameter timeToleranceSpeed) by the maximum permissible deviation
(feed axes: machine parameter speedDiffNom) from the nominal velocity value.
- Possible causes:
+ Machine parameter "timeToleranceSpeed" is defined too small
+ Machine parameter "speedDiffNom " is defined too small.
+ I component of the speed controller in the machine parameter "vCtrlIntGain" is defined too small.
+ Is the speed encoder cable connected?
+ Motor encoder defective or loose

Error correction

- Check the machine parameter "timeToleranceSpeed"
- Check the machine parameter "speedDiffNom"
- Check the I component of the speed controller machine parameter "vCtrlIntGain"
- Check the speed encoder mounting
- Check the cable of the speed encoder
- Exchange the speed encoder
- Inform your service agency
