To home a machine axis, the actual position value system of the machine axis must be synchronised


All machine axes that must be positioned and have no encoder (which supplies an actual value absolute position) must be homed.

Speed-controlled or only endlessly position-controlled spindles need not be homed.

Homing (RPF) is possible for the following axis types (P-AXIS-00018):


Homing must be parameterised for every axis in the axis parameter list.

For more information on this function, see the chapter Parameterisation.


Homing is commanded with by the NC command G74 or by starting the 'Homing’ mode.

For the sake of clarity, links to other documents and parameters are abbreviated, e.g. [PROG] for the Programming Manual or P-AXIS-00001 for an axis parameter.

For technical reasons, these links only function in the Online Help (HMTL5, CHM) but not in pdf files since pdfs do not support cross-linking.
