Hi, I was thinking about using VESC in my next project. Control AC servo with quadrature encoder connected to VESC. LinuxCNC MESA card conected to VESC with ppm input. Servo thread with PID will be on PC and VESC will be responsible for torque control based on PWM duty.
My question is if VESC use on PPM input hardware counter and if it is possible to have good resolution at about 10kHz ( of course with firmware change ).
I assume if it use hardware than at 10kHz there are 16800 steps to play with.
Next if it can handle 2500 steps/rev(10000 resolution) quadrature encoder at 3000 rpm. That is 500kHz.
This could open new field for VESC because for CNC is better to have PID on PC with torque control then using STEP/DIR and VESC has good brain for this.
Maybe next board will be 220V 20A?
thanks in advance
