We have Drake double axis grinder. Axis V and Y are on the same servo amp
A06B-6059-H223. Machine has been down for over a week. Lost all parameters. Finally uploaded all parameters and recieved a SV003 V abnormal current in servo alarm.
Though it was the motor but I changed (swapped) V and Y motors in the field and still recieved same alarm. Changed feedback cables V and Y still same alarm. Removed motors to remove any load. Y motor shaft is locked but as soon as you move the V motor shaft SV003 V abnormal current alarms.
Changed out the A06B-6059-H223 with a known working unit. Still recieve same alarm. I have also swapped motor leads at the servo but still only recieve SV003 V abnormal current alarm.
I need help!!! Is there other suggested testing I can perform????
