Phase V to Ground Fault

Hva betyr 39 ?

A phase-to-ground fault has been detected between the drive and motor on output phase V. This indicates a severe insulation breakdown or short circuit between phase V and earth ground, posing a safety hazard and risk of equipment damage.

• Short circuit detected between Phase V and ground.
• Damaged insulation on Phase V motor winding.
• Faulty Phase V output cable connection to ground.
• Ground fault within the drive's output circuitry for Phase V.

1. 1

   Check the wiring between the drive output terminal V and the motor for a grounded condition.

2. 2

   Check the motor winding for a grounded condition on phase V.

3. 3

   Replace the drive if wiring and motor are verified good.
