each time the device is switched on.
Relative positioning movements can also be carried out if
the reference system has not yet been referenced.
The reference point is determined by reference travel to the
fixed stop. Reference travel is always carried out at the stop
of the pick position.
Please note

[Count direction], the pick position will also be modified
(see also chapter 4.5.3).
The following position specifications refer to the reference
point (= zero point) after successful reference travel:
the software end positions
all absolute nominal positions.
During reference travel the drive moves slowly at reduced
search speed to the stop of the pick position and accepts the
position as the reference point (= zero point). After the set
tling time (after approx. 20 ms) the drive is at the zero point

= 0.
The search speed is specified at the factory such that the end
positions can be reached reliably even at low mass or without
additional mass.
