Setting the controller

Simplified representation of the technology controller
The technology controller is implemented as a PID controller (controller with proportional,
integral, and derivative action).
①
The inverter uses the start value when all the following conditions are simultaneously satisfied:
The technology controller supplies the main setpoint (p2251 = 0).
•
The ramp-function generator output of the technology controller has not yet reached the start value.
•

The settings required as a minimum are marked in gray in the function diagram: Interconnect
setpoint and actual values with signals of your choice, set the ramp-function generator and
controller parameters K
