8.5.3. X.LIMIT -
Limiting the Mechanical Stroke Range
This function limits the (physical) stroke to specified % values (lower and upper). In doing so, the stroke range of
the limited stroke is set equal to 100%. If the limited stroke range is left during operation, negative actual posi-
tions or actual positions greater than 100% are shown.
Factory setting: Lower position limit = 0%, upper position limit = 100%

Adjustment ranges:
Lower position limit: 0 – 50% of the entire stroke
Upper position limit: 50 – 100% of the entire stroke
The minimum distance between the upper and lower stroke limit is 50%. Therefore if one value is entered with a
minimum distance of < 50% the other value is adjusted automatically.
