One other strangeness I just found with my own 7i39 setup. I couldn't use any duty-cycle greater than 0.6. It turned out that this was because I was running a 46kHz PWM with the default 5000nS deadtime. The actual deadtime for the 7i39 is 320nS.
I was getting very wierd behaviour, the motor would be nice and stiff, then click to a position, and not be able to recover. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Master SQL Server Development, Administration, T-SQL, SSAS, SSIS, SSRS and more.
