X.LIMIT –
Limits the mechanical stroke range
This auxiliary function limits the (physical) stroke to specified % values (minimum and maximum). 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
POS
values or
POS
values greater than 100 % are indicated.
Factory setting:
Min = 0 %,
Max = 100 %
