You lose torque if the PWM duty cycle is more than 95%, so you need to make sure there is a limit to avoid that. You might still hit the drive current limit at quite a low duty-cycle, if the motor impedance is low. Increasing the PWM frequency might help. If it squeals it is probably current-limiting. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
