Description
Proportional range
Pb1
0
…9999
Size of the proportional range: The larger the P-range, the smaller
the gain of the controller. For Pb = 0, there is no efficient controller
structure (same behavior as for limit value monitoring). For a steady
controller, Pb > 0 is required.
Derivative time
Dt
0 ...
80
...
9999 [s]
Influences the differential portion of the controller output signal. The
influence of the D-portion increases with an increasing derivative
time.
0 = derivative time turned off (no D-portion)
Reset time
rt
0 ...
350
... 9999 [s]
Influences the integral portion of the controller output signal. The
influence of the I-portion becomes smaller with an increasing reset
time.
0 = reset time turned off (no I-portion)
Cycle time
Cy1
0.0 ...
20.0
...
999.9 [s]
For a switching outlet, select the cycle time as follows: the energy
supply for the process should be almost continuous, and at the same
time, the switching elements should not be overstrained.
Contact distance
db
0.0
...
999.9
Distance between the two controlling contacts in a three-point con-
troller
Switching differential
HyS1
,
HyS2 1
0.0 ...
1.0
...
999.9
Switching differential for a switching controller with proportional
range Pb = 0 (same behavior as for limit value monitoring)
Operating point
y0
-100 ...
0
...
+100
Output level for P- and PD-controller (for x = w, then y = y0)
Output level limiting
y1, y2
0 ...
100
[%]
y1: Maximum output level limiting
-100
...
+100 [%]
y2: Minimum output level limiting (only working
for Pb > 0)
The type of controller determines the display of parameters. For some parameters, the decimal places depend
upon the equipment of the device. Factory settings are shown in
