I have 6SE7024-7ED61-ZA00(G93) and use this for hoisting on crane. I have problem with precharging board in this device as the resistors of this board open and F002 accrues and the board sometimes burned. I change burned board with new one but it happens again.

What should I do?
I have a question about this fault.
I have a similar fault with a masterdrive in a crane but in the turn movement. The resistors and the precharging circuit are broken.
Its the second time that this matter and i dont know what check.
