DMU 125-P, Heidenhain I-430, Millplus 5-Axis

Machine boots fine, All axis reference fine EXCEPT for C-Axis. The machine was running production until it was moved and now this issue. When you try to reference or manually drive C-Axis I get a couple of different alarms, {C59- Motor torque to large no speed} and {Max following error to large} Think I have it narrowed to Scale or encoder. Really need help on finding out how to turn the scale off in parameters to drive the axis with just the encoder to see if the scale is really bad. Any suggestions are welcome
Thanks Stan
