P400 (Funct. analog input): „4“ (frequency addition)
P411 (setpoint frequency) [Hz]
Set frequency with 10 V at analog input 1
Example: 50 Hz
P412 (Process controller
setpoint):
CR middle position / Default setting 5V (adjust if necessary)
P413 (P controller) [%]: Factory setting 10% (adjust if necessary)
P414 (I-controller) [% / ms]: recommended 100%/s
P415 (limitation +/-) [%]
Controller limitation (see above)
Note:
In the function process controller, parameter P415 is used as a
controller limiter downstream from the PI controller. This
parameter therefore has a double function.
Example: 25% of setpoint
P416 (ramp before controller)
[s]:
Factory setting 2s

behaviour)
P420 (Funct. digital input 1): "1" Enable right
