Issue:

Missing the +10v supply on a ATV630/ATV930 drive

Product Line:

ATV630/ATV930

Environment:

Missing +10v supply

Cause:

n/a

Resolution:

Would suggest to check the incoming power at L1, L2 and L3.

Then check the DC bus at PA/+ to PC/-.

If these are both ok, then measure between 24v and 0v for 24v.

Then measure between +10v to com and if all the supplies are ok, except the +10v, then appears the Main Control Board is inoperative.

Note: The Main Control Board would need to be replaced by Schneider-Electric Field Services
