Issue:
The drive does not trip when an input phase is removed.
Product Line:
Altivar Drives
Environment:
All models and serial numbers
Cause:
1. Parameter IPL is set to no
Depending on the device type:
1) Input phase loss works by detecting the ripple in the DC Bus. If the load is not high enough, it can't detect an input phase fault.
2) Input phase loss works with the input phase detection on the rectifier circuit (ATV61/71/600/900/MX eco/MX pro) if the rectifier is thyristor controlled (power approximately >22kW).
Resolution:
1. Set Parameter IPL to yes
2. Provide additional motor load.
