Thread: VFD And Mach3

Check the documentation for your break-out board, there is usually an output on there to drive a relay to power up extra accessories.

thank you master splinter for you replay

but i want to know how to wire the vfd with the breakout board

i have cambpell breakout board is there any normal way to wire the vfd to this board
i use solid state relay to power on my old router makita
but i don't know how to do the same with the vfd
best regards

You'll need to check in the manual of your VFD. But unless it has some sort of 'resume last state' control option, you'll probably need to drive it via your CNC software.

It can be done with a relay. Switchng the VFD on and off is controlled by closing / opening a circuit across DCM / FOR outputs on the VFD. You'll need to program the VFD setting correctly though so it knows what speed to run at once the circuit is closed.

Hi Brad
thank you for your replay
the vfd manual say that i can switching the vfd on and off
they said that d1 , d2 and dcm is used to do that but i don't know what is the terminal d1,d2

and there is some setting on the vfd like
Select the terminals of D1 and D2
Parameter setting:
PD001=1 for external control
PD044=01 for RUN function
PD045=05 for switching of F/R
When K2 is opened it rotates forward, while K2 is closed it rotates
reverse.

can you help me with this

Read my build thread. I have a few pages of VFD problems I encounted and answers. Start here.... https://www.woodworkforums.com/f170/g...7/index12.html
