A900_O: Identity Fault
On the VSODC, this fault would be displayed on the seven-segment LED as a number 8.
The Drive LED's will likely not display any fault because it doesn't know what it is.
This fault should not occur in the field. This means that the drive itself was not programmed. In English, the drive is reporting itself as a zero. Frankly the unit should have never run in the first place.
Return the defective drive to your distributor.
