The reactance and inductance questions are above my pay grade and I’d be happy to hear someone explain it. :) I use these for robotics class in place of the old BJT L298, which are optimistically rated for 2 amps but have more than 2v drop at much less than that current.
Maybe I don’t understand your comment but I’m pretty sure that a 50% duty cycle PWM waveform will run the motor at half-voltage. You command the direction with INa and INb according to the Truth Table. The PWM signal will then switch either the A or B low-side FETs, depending on the INa/INb configuration. > It would appear that when enabled, and lets say with a pwm frequency near > the top of the 10khz range, that a 50% duty cycle pwm waveform would be > the equ of a balanced, at rest servo, so my first question is how much > additional inductance in series with the motors leakage reactance will > be needed to protect the chip from the current surges at the pwm > waveforms transition points? > > My hal file will obviously need to stage an initial enable at the 50% > duty points, then let the pid output thru. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
