I'm having trouble getting 10V PWM output from G540, Pin 7 (VFD Ground) and Pin 8 (VFD Output). The maximum voltage G540 is outputting is around 5V.
Below are my settings:
VFD = Huayang 2.2kW
Spindle = 2.2kW water cooled, 24,000 rpm.
I'm feeding 10V to G540 from Huayang VFD (also measured 10V). I also have the VFD analog input set to 10V.
Mach 3 RMP Reading VFD RMP Reading Voltage Across P7/P8 5,000 10,500 1.9 7,000 11,750 2.6 12,500 15,000 4.6 24,000 16,300 5.6
How do I get G540 to output 10V? How do I get the VFD and Mach 3 rpm to line up?
