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 5 V (adapt if necessary)
P413 (P controller) [%] : Factory setting 10% (adapt if necessary)
P414 (I-controller) [% / ms] : recommended 0.1

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 (if necessary, adjust to controller behaviour)
P420 (Funct. digital input 1) : “1” Enable right
P421 (Funct. Digital input 2) : "40" actual value PID process controller
