Issue:
What causes an Impendent short circuit fault?
Product Line:
ATV61, ATV71
Environment:
All
Cause:
Electrical Noise
Resolution:
- Short-circuit or earth leakage at the drive output (verify drive is grounded to earth or system ground)
- Check the integrity cables connecting the drive to the motor, and the motor
insulation, path of the motor leads (i.e. not coming into contact with potential sources of noise).
- Try running the drive "open circuit":

- Check the integrity cables connecting the drive to the motor, and the motor
insulation, path of the motor leads (i.e. not coming into contact with potential sources of noise).
- Try running the drive "open circuit":
- Turn off Output Phase Loss
- Power down the drive
- Disconnect the motor leads from the drive
- Power up the drive and see whether the fault is persistent
If the fault persists without the motor leads connected, there's a problem with the drive. If the fault does not appear while the motor leads are disconnected, check your leads and motor.
