I usually see anti-windup schemes for PID loops based on the output limits.
When the output hits 100%, don't allow the error to increase the I value
since the output is limited to 100% anyway.
That eliminates windup.
The car analogy is: If your foot is already on the floor what is the
point

Subject: Re: [Emc-developers] pid bug
I usually see anti-windup schemes
current PID behaviour doesn't allow the I term to _change_ when the output is
limited.
Yikes, that won't work! :-)
Sounds like a pretty easy fix though.
