Error description 231-A8A0
Error message
A8A0 CC nominal-to-actual deviation of position values %1
Cause of error
- The safety function nominal/actual value monitoring of position values has ascertained an excessive deviation.
- The motor is moving while the slide is not, or vice versa
- The mechanical motion transmission is interrupted
- Thermal expansion of mechanical transmission components
- The transmission ratio of the motor to the position encoder is incorrect (machine parameter distPerMotorTurn)
- Improper installation of position encoder on ball screw
- The entry in the axis-specific parameter maxPosDiff is defined too small
Error correction
- Check the mechanical motion transmission
- Check the encoder fastening
- Check the thermal expansion of the mechanical transmission components (e.g. recirculating ball screw)
- Check the transmission ratio of the motor to the position encoder
- Check the installation of the position encoder on the ball screw
- Inform your service agency.
