PID technology controller
Overview
The technology controller controls process variables, e.g. pressure, temperature, level or
flow.
Precondition
Additional functions
The U/f control or the vector control has been set.
Tools
To change the function settings, you can use a PC tool, for example.
Function description
Function diagram
The technology controller is implemented as a PID controller (controller with proportional,
integral, and differential action).
①
The converter 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.
Basic settings
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 ramp-function generator and controller parameters K
P
, T
I
and T
d
.
