hi, okuma mc 4 va osp 5020, after repairing the power supply, of the upper board of the E4809-770-015-D SVC drive, I mounted it, the green led is on, no red led or alarm is present, but the axis (A) does not move !!, then I inverted the card with the Z axis, but no signs of movement here, instead the A axis with the Z axis card works, do you have any suggestions? thank you
