4.8.2.1 Hysteresis for hardware limit switch
Via parameter
Hysteresis 1149, the switching hysteresis of a limit switch (e.g. prox-
imity switch) can be considered. In addition, the hysteresis prevents non-defined
switching when the axis has stopped at a limit switch position.
The drive can be enabled if the distance between the axis and the hardware limit
switch exceeds the value of parameter
Hysteresis 1149.

Enable possible
The HW limit switch is activated. The drive can only be enabled after the axis has
been travelled the distance of
Hysteresis 1149 opposite to the former movement.
JOG-Mode can be used to move away from a HW limit switch. Refer to section 4.5
and 4.8.2.3.
