One of our customers would like to use our small LV 3 phase HBridge (7I39) to drive a motor using EMC. I currently dont have a HostMot2 configuration that would support this (its normally used with SoftDMC), but the hardware part is pretty trivial, just a pinout change. (unless I wanted make a special 3 phase PWMGEN with 3 x 10 bit PWM gens at a single write location - thats a driver change)
The 7I39 is very simple, its just a 3 phase bridge with current limit so the interface requirements are just 3 PWM generators. What I'm wondering is if anyone has done simple sine wave PWM 3 phase drive via HAL and suitable COMPs alone? At a 4 KHz or so update rate , waveform quality would be pretty good up to normal servo speeds Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
