What to do if the motor doesn't start and an under bar appears on the GMTCNT GMD-00370H?
- JJustin LewisAug 7, 2025
If the motor doesn't start when you press the key or enter a run forward (FWD) or reverse (REV) command, and an under bar appears on the LED monitor, it could be due to low DC link bus voltage. To check this, go to Menu #5 "Maintenance Information" in Programming mode on the keypad and select 5_01. The DC link bus voltage should be 200 VDC or below for three-phase 200 V class series and 400 VDC or below for three-phase 400 V class series. To resolve this, connect the GMTCNT Inverter to a power supply that meets its input specifications.
