Description of the homing methods
Choosing a homing method by writing a value to homing method (Object 6098h) will clearly
establish:
l
the homing signal (P-Stop, N-Stop, reference switch)
l
the direction of actuation
and where appropriate
l
the position of the index pulse.
The reference position is give by the reference offset (Object 607Ch).
A detailed description of the types of homing movement can be found in the description of
WorkBench.
The following homing methods are supported:
