We're already eating into profit margin, so a brake probably isn't
going to get added. We'd need to redesign the control board (yet
again) to add the control outputs too. No way will they approve that!

I think I'll suggest we go for current reduction at idle. I'm pretty
sure we're using 2916's for drivers, and I think they support current
control. Dropping to 25% of nominal shouldn't be too much added heat
(I hope). If that doesn't work, we got some real problems to sort
out. Makes me glad that I'm the mechanical and not the electrical on
the project!
