Overview

Task

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

• with the axis coordinate system of the machine and
• the CNC.

Characteristics

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):

• Linear axes
• Rotary axes
• Spindles

Parameterisation

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

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

Programming

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