When I turn on my Fanuc A06B-6111-H006#H550 driver, alarm number 20 appears on the LED screen. Alarm description V phase current overcurrent error. Can anyone help me please, in which part of the card do I need to replace this part? I need help.

Thanks in advance

The alarm 19 is for the U phase and the alarm 20 is for the V phase.
You need to change the power board A16B-2203-0651 of the drive and the IGBT (transistor module) A50L-0001-0384 and you will be fine

I believe it will resume normal operation.

You can verify the parameters set in the driver. Make sure that the motor parameters (like rated current) are correctly configured.
