• Determination of the operating
range for the PID process control-
ler by limiting the input signal
nSet_a.
• Lenze setting: No limitation (-

(Lenze setting)
The input setpoint nNSet_a is output
without any changes at the output
nOut_a.
1 Additive + feedforward control
nNSet_a and nAct_a are used as PID
input values. The arriving nNSet_a is
additively linked to the value output
by the PID element.
2 PID as setpoint generator.
nSet_a and nAct_a are used as PID in-
put values. The input nNSet_a is not
considered.
