components can be switched on/off individually.
The P-component is switched on if the input
"Switch on P-component" is set.
I_SEL BOOL TRUE INTEGRAL ACTION ON / Switch on I-
component. In the PID algorithm, the PID
components can be switched on/off individually.
The I-component is switched on if the input
"Switch on I- component" is set.
INT_HOLD BOOL FALSE INTEGRAL ACTION HOLD / Freeze I-
component. The output of the integrator can be
frozen. To this end, the input "Freeze I-
component“ is set.
I_ITL_ON BOOL FALSE INITIALIZATION OF THE INTEGRAL ACTION /
