P400 [-01] (Funct. Analog input1) : “2” (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: Parameter P415 is used as a control limit after the PI controller.
Example: 25% of setpoint
P416 (Ramp time PI setpoint) [s] : Factory setting 2s (if necessary, adjust to match controller behaviour)
P420 [-01] (Funct. digital input 1) : "1" Enable right
P400 [-02] (Funct. Analog input 2) : "6" PI process controller actual value
