Error description 231-8C90

Error message

8C90 Amplitude too high at position encoder %1

Cause of error

- The amplitude of the position encoder signal is too high or the signal for contamination is active
- Noise on the encoder signal
- Short circuit in the encoder cable
- Encoder signal amplitude too high
- Incorrect values in the machine parameter posEncoderResistor

Error correction

- Check the encoder connection (ground connection)
- Check the encoder
- Check configuration in machine parameter posEncoderResistor. If a position encoder is used (no external Y cable), a 0 has to be entered in this machine parameter.
