When powered&booted the z-axis makes a high frequency whine when the axis is not in use if left long enough the machine alarms out (200-4 alarm-a svp system z-axis 410555) if you try to move the axis before it alarms out a “over diff” alarm pops up.
I have I spare svpiid board and so I went ahead and swapped them out and there was no improvement I still get the same code what are your guy’s opinions? What would make the motor make a high pitched whine when not even moving the axis? I’ll take as many suggestions you guys might have need to get this okuma running to get some jobs out..
