Configuration
8200SHB0199
7-37
Subtractive influence
of the process controller
Conditions:
C051 = Positive actual value
C181 = Select positive setpoint
C238 = -1- (with frequency precontrol)
Potentiometer connections of the dancer
- Beginning (A) = + 10 V
- End (E) = GND
The direction of control action of the process controller is substracted from the main setpoint.

Important Caution
The direction of rotation must not be changed, if the process controller is used as speed controller.
If C070 = 0.0, the proportional component K
P
is not active.
If C071 = 9999, the integral component K
I
is not active.
If C072 = 0.0, the differential component K
D
is not active.
The process controller is not suitable for inverse process control.
(Inverse control means thatthe speedbecomes lower, if the actualvalue islower thanthe
setpoint.)
Inverse controls are for instance, vacuum pressure control or humidity controls. Here, the 93XX
VECTOR should be used.
