Process controller (PCTRL1)

Purpose
The FB is used, for instance, as a higher−level controller (dancer position controller, tension controller,
pressure controller etc.).
The control characteristic follows the ideal PID algorithm, but it can also be changed over to a PI or
P characteristic.

Function
Setpoint and actual value are sent to the process controller via the corresponding inputs and
processed according to the selected control algorithm (control chararacteristic).

Note
Input of the process setpoint. Possible
value range: ±200%. The time
characteristic of step−change signals can
be affected via the ramp function generator
(C0332 for the acceleration time; C0333 for
the deceleration time).
Actual value input; value range ±200%
