0.0 % 199.9 Operating range
• Determination of the operating
range for the PID process control-
ler by limiting the input signal
nSet_a.
• Lenze setting: No limitation (-
199.9 % ... +199.9 %)
C242 Operating mode
0 Off
(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.
3 PID setpoint from L_NSet_1 nNSet_a and nAct_a are used as PID
input values. The input nSet_a is not
considered.
