Error message

8C00 Encoder on speed input %.2s is defective

Cause of error

- There is no motor encoder signal
- There is a break in the motor encoder cable
- The signal amplitude of the motor encoder is missing or too small
- The motor encoder is contaminated
- Incorrect parameters of MP116.1(CC424) or MP118/Bit 1 during use of an external Y cable

Error correction

- Check the motor encoder connection
- Check the motor encoder for proper function
- Check the amplitude of the motor encoder signal
- Check the setting in MP116.1 or MP118/Bit 1. If an external Y cable is used, a 1 has to be entered in this machine parameter.
