Environment:
All
Cause:
Temporary voltage drops is causing UVR - Under voltage fault
Resolution:
Go to Drive Menu > 1.8 Fault Management > Undervoltage Mgt, and change the Undervoltage timeout from 0.2s to somewhere between 5-10s.
If the line voltage is less than 480VAC, we can also look at adjusting the Mains Voltage setting to 460V which lowers the trip level for the Undervoltage fault.
