Description
The input AC voltage to the rectifier unit at drive unit position arg is too high.
Consequences
No operation is possible until the fault is corrected. The system will go to "Motor Off" state.
Possible causes
- The AC voltage level at the rectifier input is too high.
Recommended actions
- Check the input supply voltage.
- If this is a newly installed system equipped with a power transformer - Check the voltage selection of the transformer.
- If the problem persists, replace the unit.
