Phase V to Gnd

Was bedeutet F39 ?

A grounded phase condition has been detected specifically on motor phase V or in the wiring connecting drive output terminal V to the motor. This indicates a direct short path to ground.

• Phase V winding shorted to ground in the motor.
• Cable insulation failure between phase V and ground.
• Internal drive fault with phase V output stage.
• Grounding fault on phase V line conductor.

1. 1

   Disconnect the motor from the drive output terminals (U, V, W).

2. 2

   Measure insulation resistance between drive output terminal V and earth ground using a megger at 500VDC; expect a reading greater than 1 MΩ.

3. 3

   Measure insulation resistance between motor phase V and the motor frame using a megger at 500VDC; expect a reading greater than 1 MΩ.

4. 4

   Inspect the wiring connecting drive output terminal V and motor phase V for any physical damage or signs of insulation breakdown.
