Parameter for defining the close time of a valve, flap, etc.
Value range
Unit
Recommended range
63...65535 0.1
s
6.5...600 s
The fall time (100% to 0 %) can be defined within the range specified above.
4.12.10 BreakTime
Parameter for defining the break time (pause) when a drive changes direction
(open/close).
Value range
Unit
0...255 0.1
s
4.12.11 NeutralZone
Parameter for setting the percentage share of the extent of a neutral zone (in
relationship to the required time).
Value range
Unit
0...20 0.1
s
Is the difference between the process value and path algorithm greater than half of
the neutral zone plus hysterisis, a pulse of appropriate length and direction is
generated until the difference value is again within the neutral zone.
4.12.12 Hysteresis
(Switching Limit)
Parameter for defining the component of deviation between [StrokeModel] and the
process value [AOVal].
The process value must be reached until the [StrokeModel] has been adjusted and,
as a result, an OnCmd or OffCmd pulse has been generated..
The entire deviation
