I have a 98 Mycenter Zero with the Yaskawa Drive. When I do a M19, it will not orientate. It just rocks back and forth. Looking at the schematic, I was looking for an amplifier for the magnet. Cant find the magnet, nor the amplifier. Kitamura says there is not an encoder on the spindle motor. I am at a lose. I could really use some help, anyone else ever have this problem? Any help is definitely appreciated
