Here is the oddity. The y-axis has alarmed twice at the SAME exact X-position...??? It usually occurs after about one-two hours of machine idle time. Mori tech originally said look at the wire harnesses, except they don't move with the table on this machine. then suggested checking the brushes. same as everyone else.
Checked brushes & Y-axis commutator. Brushes look great, commutator looked a little iffy. All brushes were replaced at the same time when the machine was setup.
The Z-axis has alarmed once, overCurrent, yet at the same time as the Y-axis Overvoltage error. Huh? How is that related? One time Z-axis by itself as OverCurrent.
All the calibration voltages check out O.K. rotary Phase converter, Wild leg is 15V higher than input legs.
