Go to Zero Point
Parameter A 110
The direction of zero point search is specified in this parameter as well as
the type of feed axis (linear axis or rotary table) and the position encoder
(incremental or absolute).
Rotational direction of the motor with zero point search (looking onto motor
shaft)

Decimal places: 2 or 3 depends on parameter B 007
Limits only effective with absolute position detection or after homing.
In setup mode, the drive stops upon reaching the travel range limit without
emitting an error message.
In automatic mode, an error message is generated once the programmed
position exceeds the travel range limit.
The position of the travel range limit as it relates to the zero point of the
machine is not affected, i.e., shifted, by offset programming (A 111).
