Hi,

It could also be that the XPS axis is in the wrong 'state'. I think it needs to be in 'ready state' (states 10 to 13) to receive move commands.

I updated the XPS driver recently. So in the next release of the motor support module the driver should indicate if there is a problem (via the motor record MSTA field). So if the axis is in a state which means you can't move it then you will be notified by the record going into alarm state.

Cheers,
Matthew
