After doing the changes as instructed by Mark,(changing from scale to resolver reading), the machine was working great. The problem occured when I did a bone headed move, I told the machine to align while I went to replace the covers.
This is when the table traveled off axis limits...(we think). When I looked at the control touch screen I had the error. I looked in the cabinet and there was the flashing "P".
I can not remove the resolver cable with out distroying it, I would have to cut off one end,(RS232 or the Canon Plug), and then pull it through the maze of hold downs, clamps and strain reliefs. The power (motor) wire tested good, I will send it if you want, with the motor you just rebuilt.
