Reading on the web some say that the Mach3 Motor Tuning and Setup screen has no affect when using PWM and some say to set the Stepsper to 1000, increase the Velocity / Acceleration to maximum and set the Step pulse to 5, Direction pulse to 1. I wonder which one is true
On my PWM system with G540 and a 400Hz / 24K RPM spindle I get the following with my pulley set to min=0 and max=24000, ratio=1
M3S6000 / 188Hz on the VFD, It should be 100Hz
S12000 / 256, it should be 200Hz
S18000 / 324, it should be 300Hz
I didn’t try yet S24000 since the spindle is new and will try this speed later
Should I play with the numbers on the Motor Tuning & Setup page to get the right frequency?
