Drive supported execution of the CNC based homing (P-AXIS-00386)

By default, CNC controlled homing for SERCOS drive is done completely in the control, the drive internal positions are not altered.

If the drive supports SERCOS command S-0-146 (CNC controlled homing) with this parameter can be activated that this command is used for CNC controlled homing. The advantage of this method is that after homing is finished the drive internal positions are referenced, too, so that for example drive internal software limit switches can be used.

The reference position used for homing is P-AXIS-00152, this value is transferred to the drive during homing.

Drive supported execution of the CNC based homing (P-AXIS-00386) 2:

Additionally to command S-0-146 the drive must support the following commands:
· S-0-171 (Calculate displacement)
· S-0-172 (Displacement to referenced system)
· S-0-191 (Cancel reference point procedure)
