P411 (setpoint frequency) [Hz] : Set frequency with 10 V at analogue 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 (limi/-) [%] : 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)
