10.3.2 Parameter settings affecting the process controller
(Example: setpoint frequency: 50 Hz, control limits: +/- 25%)

P400 (fct. analogue input) : "4" (frequency addition)
P411 (setpoint frequ.) [Hz] : setpoint frequency with 10 volts applied to analogue input 1
: example 50 Hz
P412 (setp, process contr.) : midway position dancing roller / factory setting 5 V (adjust if required)
P413 (P-controller) [%] : factory setting 10% (adjust if required)
P414 (I-controller) [% / ms] : 0,1

P415 (limitation +/-) [%] : controller limitation (see above)
Note: The process controller function provides for parameter P415
to ensure a limitation of the controller downstream of the PI
controller. In other words this parameter has a double effect.
Example 25% of the setpoint
P416 (ramp prior to contr.) [s] : factory setting 2s (align to control action if required)
P420 (fct. digital input 1) : "1" enable right (clockwise rotation of magnetic field)
P421 (fct. digital input 2) : "40" actual value PID process controller
Alternatively analogue input 2 (P405=14)
can be used as a multinational I/O, too.
