Gantry monitoring during drive controlled homing (P-AXIS-00298)

If for a gantry configuration gantry distance monitoring before homing is activated (P-AXIS-00249) a gantry error occurs during drive guided homing (e. G. for SERCOS drives) when the drive sets its actual position to the reference position at the end of the homing cycle. In this case the gantry error occurs near the reference position of either the master or the slave drive.

In order to activate gantry distance monitoring during homing it is possible to suppress this gantry error and to trigger a new calculation of the offset between master and slave axis if a gantry error occurs within a certain range around the reference position. This range of tolerance can be set up with this parameter.
