Simplified representation of the technology controller
The technology controller is implemented as PID controller (controller with proportional,
integral and differential component) which means that it can be very flexibly adapted.

①
The inverter uses the start value when all the following conditions are 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.
For more information, refer to the parameter descriptions and the function block diagrams
7950 - 7958 of the List Manual.
Optimizing a closed-loop controller
You optimize the technology controller as described in Section Optimizing the closed-loop
speed controller (Page 358).
