Load ramp generator (only PCTRL2)
A jerk−free acting of the process controller is possible only when the setpoint ramp generator has
previously been loaded with the actual value.
l
PCTRL2−RFG−LOAD = HIGH activates the function.
l
The start value (e.g. the actual value) is entered via PCTRL2−RFG−SET.

Value range of the output signal
Range of the process controller
PCTRL1
PCTRL2
Limitation
Bipolar (default setting)
C0337 = 0
C1335 = 0
Limits the output value to ±100 %
Unipolar
C0337 = 1
C1335 = 1
Limits the output value to 0 ... +100 %
2.4.50.4
Evaluating the output signal
After the limitation, the output signal is evaluated.
PCTRL1
You can enter the influence of the process controller via PCTRL1−INFLU.
l
With PCTRL1−INFLU = 100 %, the output signal of the controller is output unchanged. The
influence changes in relation to the value at PCTRL1−INFLU.
PCTRL2
The overlay function of the process controller can be slowly activated or deactivated using an internal
ramp generator.
l
The influence of the process controller is entered via PCTRL2−INFL.
l
The influence is activated with PCTRL2−OVERLAY = HIGH.
l
The influence is deactivated with PCTRL2−OVERLAY = LOW.
l
Ramps for activation and deactivation:
– C1336 = Acceleration time T
ir
– C1337 = Deceleration time T

Deactivating the process controller
l
The process controller is deactivated using PCTRLx−INACT = HIGH.
– PCTRLx−OUT is set to zero.
– The I−component is set to zero.
– The ramp generator is set to zero.
