1994 Arrow 500
CT control, drives, motors.
Fired up the machine today, powered on the servos, pushed the alignment button...
halted with a spindle drive fault.
Drive display shows -OC- (overcurrent?)
Voltage looks okay everywhere.
Checked the wires, nothing appears loose.
Reseated all of the connectors.
Tried a couple more times.
Always got a spindle drive fault, sometimes the drive displayed -OC-, sometimes -UU-, sometimed rdy (ready, no fault).
Anybody know of any problem areas to check before I send the drive out for service?
