Implementing feedforward on PLC5 PID

PLC 5/20 using PD type control block
When implemetning a feedforward control do ya'll use the .bias or do you just add the feed forward to the PID .out before sending to the analog output?

I need to turn a sharp corner and after an afternoon of tweaking it appears that I'm going to have to resort to a bit of feedforward.

I use the .bias because the anti-reset windup implementation accounts for its use.

I would just add it to the .bias. The PID block may do some limit checking for you. Either way you will be OK.
