Homing Mode: Short Cam with Marker

Short Cam with Marker

In the Short Cam with Marker homing mode, the reference point is preset at the negative side of the zero marker, when coming in positive direction at low velocity.

The Short Cam with Zero Marker homing mode uses the two homing-specific inputs:

The Proximity&LimitSwitch input: used as the proximity signal. On the falling edge of the signal, the axis decelerates to change direction.
The Origin input used as Zero Marker signal.

The detected errors that can be encountered:

If Drive_Ready&Emergency goes off (if not disabled and Drive_Enable output is active), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0).

The detected errors are also reported in the AXIS_FLT implicit status object (%IWr.m.c.6.3).

Limit crossing detection: The Proximity&LimitSwitch input can not be used as a Limit Switch input, either for homing commands or any other command. Instead use the Drive_Ready&Emergency input in order to detect a limit-crossing event.
