5.7 Drive functions
5.7.1 Homing
When the device is switched on, homing must be carried out
before a positioning task can be executed.
The drive homes against a stop or a reference switch. A stop
is reached when there is an increase in the motor current at
the same time as the drive shaft comes to a stop. As the drive
must not position continuously against the stop, it must move
at least 1 mm into the stroke range again (offset axis zero
point).
Sequence
1. Search for the reference point in accordance with the
configured method.
2. Move from the reference point to the axis zero point
(offset axis zero point).
3. Set at axis zero point:
Current position = 0 ć project zero point offset
(that is −PZ).
