2.7.5.1 Control characteristic

In the default setting, the PID algorithm is active.

Differential component K

You can deactivate the K

−component by setting nKd = 0.0. The controller now becomes a

PI−controller (or P−controller if the I−component is also switched off).

Integral−action component I

You can switch off the I−component with

 bIOff_b = TRUE, or on with

 bIOff_b = FALSE.

Switching on and off can also be done online. If the I−component is to be switched off permanently,

set bIOff_b to TRUE.

Integral−action time T

By using nTn you can set the parameter for the integral−action time.
