Table 6-42 Adapting the actual value of the technology controller
Parameter Description Setting
p2267 Technology controller upper
limit actual value [%]
Factory setting: 100 %
p2268 Technology controller lower
limit actual value [%]
Factory setting: -100 %
p2269 Technology controller gain
actual value [%]
Factory setting: 100 %
p2271 Technology controller actual
value inversion
Technology controller actual value inversion
If the actual value decreases with increasing motor speed, then p2271
must be set = 1.
0: no inversion
1: actual value signal is inverted
Factory setting: 0
p2270 Technology controller actual
value function
Technology controller actual value function
0: no function
1: √
2: x
2
3: x
3
Factory setting: 0
Further information
For additional information refer to the function diagrams 7950 ff of the List Manual.
You will find additional information on the following PID controller components in the Internet
at:
● Setpoint input: Analog value or fixed setpoint
● Setpoint channel: Scaling, ramp-function generator and filter
● Actual value channel: Filter, limiting and signal processing
● PID controller Principle of operation of the D component, inhibiting the I component and
the control sense
● Enable, limiting the controller output and fault response
