VFD Wiring

[JAZZCNC]

These are the connections. You will also need to set some parameters in the VFD, if the VFD as got a potentiometer on the front then you may need to change the jumper on the side from VR to VI but this can depend on the model, some have it, some don't.
You will also need to setup your controllers spindle setup and outputs for it to work.

Speed control
G540 pin7 = ACM
Pin8 = VI
Pin9 = +10

On/Off

You will need a relay for this and it can be controlled using an Output. I will use Output 1 in this example but it could be any you want.

G540 pin5 = Relay 0v side of coil. The positive +V side goes directly to the DC PSU your using. The PSU and G540 must share the same GND.
Then run wire from DCM on the VFD thru the relay contact and back to FOR on VFD.

After you have set the VFD parameters and your control software Spindle setup then you should be good to go.
