Hitachi Seiki HC 500 Z Axis won't move
Working on an old HC 500 with pallet changer. Fanuc 10M control. The Z axis will not move with toggle or hand wheel. NO alarms. Had a spindle alarm and shut down and rebooted control and now this.
All other axis work and home. Spindle comes on. Acts like the machine does not see the Z axis at all. Checked all switches for tool changer and door switches.. All ok .
Swapped the X and Z drives and changed jumpers but still nothing. No alarm lights on any of the drives including the SDU. Checked parameters concerning the Z axis but nothing looks out of the ordinary. Fanuc seems to think it's a MB problem but I'm not totally convinced yet. It's like a parameter is turned off for the Z axis.
Any help would be great.

Here is a shot in the dark - but does it know the status of the tool clamp/unclamp? That will block the Z Axis . Any alarm data on the main or Seicos maintenance screen?

I'll look at the tool clamp/unclamp Diag tomorrow. Thanks
