Min (Overlap Compensation); Max (Output Scaling); Trigger (Threshold Value Of Min Function) - WEST PAM-198-P Technical Documentation Manual

5.4.3 MIN (Overlap compensation)

5.4.4 MAX (Output scaling)

5.4.5 TRIGGER (Threshold value of MIN function)

Command
MIN:I
MAX:I
TRIGGER
The output signal is adapted to the valve by these commands. With the MAX value the output signal (the maxi-
mum valve current) will be defined. With the MIN value the overlap (dead band of the valve) will be compen-
sated. Via the TRIGGER the activation point of the MIN function is set and so a non-sensitive range around
1
the zero-point can be specified.
If the CC command is used, the TRIGGER of the MIN/MAX function should be set to 0 and
the function should not be used if possible. Both functions influence each other and make the
behavior really difficult to evaluate.
CAUTION: If the MIN value is set too high, it influences the minimal velocity, which cannot be
adjusted any longer.
MIN:B
MAX:B
1
This dead band is necessary, in order to avoid unrequested activations caused by small variations of the input signal. If
this module is used in a position controls, the TRIGGER value should be reduced (typical: 1...10).
