POSSIBLE CAUSE
Check phase-to-phase and phase-to-ground distribution bus voltage.
Increase Line Voltage Imbalance% in CFGUMVFD screen.
Check Power Supply
If operating from a generator, check generator size and speed.
Check utility power supply.
Check VFD communication wiring and connectors.
Check status lights on DPI Communications Interface Board.
Call Carrier Service.
Check fault code and possible cause in corresponding type of VFD user
manuals
Call Carrier Service
The VFD Start Inhibit is derived from the Alarm bit being set in the VFD.
The conditions causing the alarm must be corrected in the VFD to
enable subsequent starts and operation
Press Reset to Restore Configuration.
Actual VFD checksum does not match calculated value.
Check Temp Switch and Cooling Fans.
Check for cooling fan air flow obstructions
Load compatible version files into drive
Check the main power to VFD
