Hi,
I have tried to hook up the G540 vfd to my new x2 mill motor control that i purchased from Surplus Center. I used pminmo.com G540 VFD directions but this did not work. I talked to tech. support at Gecko and they informed me i needed to add an independent power source 10 volts to pos 9 and pos 7. I did this and was able to get 0 to 10v increase/ decrease, m3 and m5 shutdown through mach 3 control on pos 8 out. The G540 was not connected to the motor control just a Volt meter. Once hooked to the new motor control i could not get it to control the board? The board has a 5k pot and works fine with the pot. If i disconnect the pot the spindle ramps up to full rpm? Anyone have there x2 running spindle control from the g540 and care to share their wiring diagram?
