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, e.g. caused 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 compared to the position used in the controller.

For axis set-ups where it is guaranteed that no such shift can occur during gear switching, this parameter can suppress the reset of the 'referenced' flag when the gear is switched.

This parameter is available as of CNC Build V3.01.3052.11 or higher.


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 controller. It is the responsibility of the user to check if the conditions for using this parameter are fulfilled.
