Axis remains referenced after resolution change (P-AXIS-00538)


Axis remains referenced after resolution change


By default the 'referenced' flag of an axis is cleared when the encoder resolution changes caused e. g. by a gear change. The reason for this behaviour is that, depending on the mechanical design of the axis (mounting place of encoder, mechanical structure of the gearbox, sequence of gearbox switching, etc.), the mechanical axis position can be shifted against the position used in the control.

For axis set-ups, where it is guaranteed that no such shift can occur during switching the gear, it's possible to suppress resetting the 'referenced' flag on switching the gear by using this parameter.

This parameter is available from CNC version V3.01.3052.11 onwards.


Using this parameter with axis configurations not suitable for such an application, an offset may occur between the mechanical axis position and the axis position used in the control. It is the responsibility of the user to check if the conditions for using this parameter are fulfilled.
