Operation
8.3.2 Changing the control
parameters
After entering the operating menu (see sec-
tion 8.3.1), the control parameters are
changed in the Control parameters menu
item. Depending on the control behavior, the
proportional-action coefficient KP, reset time
TN, derivative-action time TV, derivative-ac-
tion gain TV.K and operating point Y0 can
be changed:

If on-off/three-step outputs are configured
with pulse width modulation (PWM), the cor
-
responding duty cycles ( SO1.P+, SO1.P–,
SO2.P+, SO2.P– ) can be changed.
Example: The reset time TN for Controller [1]
is to be changed to 100 s.

The actual value at the comparator
PV0 ( ), the set point at the compara-
tor SP0 ( ) and the manipulated vari-
able Y ( ) are indicated on the left
(for ratio control: Actual ratio PVR, ra-
tio set point SPR and manipulated vari-
able Y).
Their course within the last minute in
the 0 to 100 % range of the measuring
range is plotted on the right.
The current value of the proportion-
al-action coefficient KP is indicated be -
low.
