866.x ARS/SRM: Piezo position out of tolerance
Description
ARS with piezo actuator
The position of the piezo actuator is set to an analog setpoint value. The function of the piezo is tested in the OFF position of the machine. If the piezo cannot be adjusted, an error will be triggered.
The monitoring is active if the parameter ArsFunctionCheckValue is > 0 Volt.
Remedy
- Check piezo and wiring (see ARS Manual, chapter "Maintenance").
- ChangeArsFunctionCheckValue piezo parameter (see ARS Set basic parameters).
- Parameter ArsFunctionCheckValue = 0 Volt -> the position is not monitored.
- Diagnosis of external devices.
- Check the digital input.
