1.5.3 Homing
In the case of drives with incremental measuring system,
homing must always be carried out after the drive is switched
on.
The following homing modes are permitted:
– Search for stop in a negative direction
– Search for stop in a positive direction
– Search for reference switch in a positive direction
– Search for reference switch in a negative direction
(default).
In order to search for the reference point and for positioning
the drive in the axis zero point, you can set two different
speeds.
Homing sequence:
1. Search for the reference point in accordance with the
configured method.
2. Move from reference point to axis zero point AZ (offset
axis zero point)
After successful homing the drive stands at the axis zero
point AZ. On initial commissioning or following a change of
homing method the axis zero offset is = 0; after homing the
drive is then positioned at the reference point (REF).
