Error message

8C90 Amplitude too high at position encoder %.2s

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 parameters of MP116.1(CC424) or MP118/Bit 1

Error correction

- Check the encoder connection (ground connection)
- Check the encoder
- Check the setting in MP116.1 or MP118/Bit 1. If a position encoder is used (no external Y cable), a 0 has to be entered in this machine parameter.
