Segment types
Dependent on segment type, the following parameters can be altered:
Wp i Target setpoint
D i Control value in segment i
Tp i Segment duration
Rt i Segment gradient
Typ i Segment type
Ramp segment (time)
With a ramp segment (time), the runs linearly from the start value (end of previous segment) to
-
wards the target (Wp) of the relevant segment during time Tp (segment duration).
Ramp segment (gradient)
With a ramp segment (gradient), the runs linearly from the start value (end value of previous seg
-
ment) towards the target value (Wp) of the relevant segment. The gradient is determined by para
-
meter Rt.
Hold segment
With a hold segment, the end of the previous segment is output constantly during a defined time
which is determined by parameter Tp.
Step segment
With a step segment, the program goes directly to the value specified in parameter Wp.
The reached due to the step change is kept constant during the time determined in parameter Tp.
Waiting and operator call
All segment types can be combined with ”Wait at the end and operator call”.
If a segment with combination ”wait” was configured, the programmer goes to stop mode at the segment end. Now,
the programmer can be restarted by pressing the H-key.
