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 (if necessary, adjust to match controller
behaviour)

P420 (Funct. digital input 1):

"1" Enable right

P405 (Funct. Analoginput 2):
