0

Off

The actual value at nAct_a is not

changed for further processing.

1

On

The square root of the actual value at

nAct_a is taken for further

processing.

C00242

Operating mode

• Lenze setting: "0: Off"

0 Off

The input setpoint nNSet_a is output

without any changes at the output

nOut_a.

1 nNSet + nNSet_PID

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 nSet_PID

nSet_a and nAct_a are used as PID

input values. The input nNSet_a is

not considered.

3 nNSet_PID

nNSet_a and nAct_a are used as PID

input values. The input nSet_a is not

considered.

4 nNSet + nSet_PID

nSet_a and nAct_a are used as PID

input values. The arriving nNSet_a

setpoint is additively linked to the

value output by the PID element.

5 nNSet || nSet_PID

nSet_a and nAct_a are used as PID

input values. The setpoint nNSet_a is

output at the output nOut_a . The

PID output value is output at the

output nPIDOut_a.
