Regarding the Function Config / Calibrate Spindle I was told that’s if you have PID.
I have ordered a RS485 adapter and when I get it I will try the Mach3 Plugin which as I understand gives good results for PWM systems.
Today I set my pulley max to 6000 RPM (ratio is always 1:1) and when I do M3S6000 the spindle went to 23479 RPM / 391Hz, the voltage from G540 to VFD was 9.53v
Changing the pulley max to 24000 RPM I get with M3S6000 spindle = 11300 RPM / 188Hz / 2.29v
It looks like the pulley setting has a big effect on the spindle but I don’t know the relation. I find it strange that when I set the pulley to max 6000 RPM the spindle will go to almost 24K RPM, 400 Hz and almost 10v. I other words increasing the pulley max. decreases the spindle RPM.
Any ideas?
