Inverter with CU230P-2 Control Units
290 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
The technology controller controls process variables, e.g. pressure, temperature, level or
flow.

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

① The inverter uses the start value if the following conditions are met simultaneously:
● 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.
Optimizing a closed-loop controller
You optimize the technology controller as described in Section Optimizing the speed
controller (Page 257).
