Dear Champs,

I am asking this for our customer.

We are confused if 1.0 is set for lk, does it mean to disable (not required) or to enable it?

From the below description, it seems 1.0 is to disable it.

And from the below figure, what does it mean by "==0?"

Would you please explain it in more detail?

Wayne,

Please see the other post for more information:

1.0 means no saturation.

The "==0" block means if the result of the v9 and uk compare is zero, then v12 will be set to 1.0. Otherwise it will be 0.0.

The equivalent C coded controller is PID_C3. You can find the source code in "DCLF32.h", and the line which performs this action is 515.

Regards,

Richard
