IR ADV 400i ERROR E010-001

HI,




IR ADV 400i has error code E010-001 (main motor 2 rotation error )

I have removed the main drive assembly and I check manually and the motors turn right

I exchanged the power supply with other Ir Adv 400i (NUMBER2) and it is working.

I exchanged the engine controller PCB assy with the Ir Adv 400i (NUMBER2) and appeared the error code E010-001 but now I have two ir Adv 400i with the same problem.

In conclusion I have an IR Adv 400i that kills the engine controller PCB assy, What do you think is the responsible for that..... the main drive assembly? the High voltage PCB assembly?

How can I find the problem without risks?

I hope to hear from you soon


ALL THE BEST
