V1204, 2.29
Parameter 71:
Gap prestop positive
Range : 0 - 99
Unit : AD value
Default : 0
Function
Due to the inertia of the Gap system there can be some overshoot after the control output has
been switched off. To prevent such overshoot, the 'Gap prestop' can be programmed.
This parameter can be regarded as a programmable offset. The control will take this offset
into account when positioning the Gap. When the Gap system approaches the programmed
position, the control output is switched off at a certain distance (Gap prestop) before the Gap
has reached position. The ‘Gap prestop positive’ must be programmed for Gap movement in
the positive direction.

The value is programmed in AD-points: a converted digital value of the position feedback
voltage of the potentiometer.
Parameter 72:
Gap prestop negative
Range : 0 - 99
Unit : AD value
Default : 0
Function
This parameter has the same definition as parameter "Gap Prestop Positive" but
only in the negative direction of the gap adjustment (smaller gap).
