Hello to all
One year ago I started building a large CNC milling machine.
I've installed steper motors (nema42), dirvers, connected to AKZ250 and everything works great. But
on the final step, when I came to spindle setup everything became very complicated for me.
I hoped to find solutions on youtube tutorials, where everything is wired and configured in 5 minutes, but VFD that I got from China has different inputs.
here is what I have:
- this is inverter (VFD) manual
- this is AKZ250 manual I'm try to use diagram on page 59
this is inverter model: GT-4R0G-2
my firs steps was like in youtube wiring - PWM, 10v from VFD+1k resistor in VI2 input, but it didn't work.
After this I asked for help manufacturer, I asked how could I control VFD with PWM signal and this is what thay sent to me
I've made the same vfd setup:
P001 - 1
P003 - 60
P004 - 60
P007 - 2
P202 - 1
and made wiring like this:
Attachment 383838
Attachment 383840
and this is how it looks like, when spindlde starts on 2000RPM.

I am very beginner in this and my electrical knowledge is very poor in this business. I dont ever understand how PWM +10v works.
I will appreciate any help.
