Hopfully the repair facility replaced the Firing board as well as the IGBT's :tired:
And did a complete test on it.
The only other issued is if the motor itself has a problem? Hopefully the fuses went before the drive blew again.
I would replace the fuses and disconnect the motor completely from the drive and power up, if the fuse blows or you get an AL-12, it is most likely the drive again.
If they hang in there with no alarm, check the motor.
