If "Homing output cam and encoder zero mark" is selected as the homing mode (refer to the
following two figures), the evaluation position of the zero mark can be selected via zero mark
and the approach direction via Start homing.
The homing cam must be applied at a freely selected digital input of the SIMATIC that was
configured in the Axis homing window (refer to the following two figures). When this homing
cam is reached, homing is enabled in the drive.
