6.18 PID technology controller

6.18 PID technology controller
The technology controller controls process variables, e.g. pressure, temperature, level or flow.
Figure 6-30
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.
