Hello,

I have been working with a Hanland Vertical Machining Centre with a Fanuc Oi MD control. For a few days now it has been stuck on the +Z axis Overtravel, when I try to press the servo release button and the -Z button, nothing happens ( does not move even a mm).

When I reduced the Z feedrate in the parameters and tried pressing the servo release button together with +Z button the axis moves. that is the problem it moves in all other direction expect the -Z direction.

I have now run out of ideas on what could be wrong coz initially I thought it was the z axis motor which had a problem but now since it can move up and not down I don't understand what the problem is.

Kindly help me in this?
