Hey guys I need some help.

I have a Monarch VMC with a Fanuc 15MF model B control. Last night they were running a part taking a heavy cut and the machine kicked out. They Zero Returned the machine. Every Axis homes fine except the table rotarty axis. It alarms out with PS200 PUlSE CODER INVALID ZERO RETURN ERROR.

The description says that the grid position could not be obtained because no one-revolution signal was applied before leaving deceleration dog in grid zero return using a digital position detector.

Any ideas? Would grid shifting the machine clear the problem? Or is it something like home has to be refound?
