Maximum distance when moving from reference cam (P-AXIS-00531)


Maximum distance when moving from the reference cam


This parameter limits the maximum movement distance when moving from the reference cam.

Setting this parameter to a value > 0 enables this monitoring.

When the set-up distance is exceeded, error message P-ERR-70523 is output and homing is aborted. So it can be prevented that in case of a 'hanging' reference switch, the movement of the reference cam is not stopped.

For modulo axes (see P-AXIS-00018, ACHS_TYP_ROTATOR or ACHS_TYP_SPINDEL) the set up maximum distance has to be less than the modulo range, otherwise error message P-ERR-110600 is output and the value of the parameter is limited to the modulo range. Setting the parameter to an negative value also results in error message P-ERR-110600 and the value is set to 0.
