Hi all, Im setting up a machine with a Mesa 5i20 driving 3 DC servos via homemade PWM/DIR amps. I've got a couple of very nice ServoDisc DC servos (0-3000rpm within 60 degrees of rotation!). I also want to get another I've seen with a 120:1 harmonic drive for a future rotational axis.
Question is this: To cut down on the ridiculous size of the output inductors I'll need for the ServoDisc amps Id like to use at least 40khz PWM, but I've also got an ESA 6F2 (3000rpm 120V 3.5Nm @9A - 17.5Nm @45A) which Id like to drive using 2 of 3 half bridges from an integrated gatedriver IGBT module which only goes up to 20khz PWM. Can I have 40khz or more on 1 or 2 pwmgens and 20khz on another 2? I know bugger all about FPGAs, VHDL etc so making a custom firmware isnt an option, just learning Linux and moving from TTL and PICs to power electronics has opened up a big enough can of whoop ass on me for now.
