Error message

1800E Excessive motor encoder frequency %1

Cause of error

- The permissible encoder frequency at the motor encoder input was far exceeded.
The monitoring thresholds are:
- MP 2561.x, bit 0 = 0: 600 kHz
- MP 2561.x, bit 0 = 1: 1000 kHz

Error correction

- Reduce the max. motor speed
- Set the parameter of the motor encoder's input circuit to high frequency (not with CC 424): MP 2561.x, bit 0 = 1
- Inform your service agency
