Tab. 235 Homing methods
4.4.3.1 Method 37: Current position
The reference mark is found by the current axis position.
Sequence:
1. Set reference mark: current position is taken as the reference mark.
2. Set axis zero-point: the axis zero-point is set with reference to the reference mark.
3. Report status: "homing status" is set.
Travel to the axis zero-point
è 4.4.3.10 Travel to axis zero-point.
Method 37: Current position
Tab. 236 Sequence principle: current position
4.4.3.2 Method 33/34: current position with zero pulse in negative/positive direction
The reference mark is found by the first zero pulse of the encoder.
