Pretty different results on 7209 so far. With 7209 I've used two wire control, and duty cycles and behavior overall is pretty different. On my TODO list is to run 7209 with three-wire control same as I use on VNH2SP30.
At the moment focusing on VNH2SP30 since it works better, at the moment the focus is learning how to tune PID and establishing a better base line. Once VNH2SP30 is great, will try to repeat same on 7209.
I guess I've suggested a few times to build a bench setup a few times already?
