Does anyone hav a schematic of Bob Campbells breakout board wired to 4 Viper 200 drives with a vfd, estop button, and home switches. I know this is a long shot, but I have to try.
IF NOT...
If I draw one, can I get someone to verify it?
Thanks

Is that the combo board with the 0-10 volt circuitry on it ?

For the VFD, yes. It is the Breakout Board Plus for Mach2&3.
Thanks

Evey VFD is different. I'm familiar with ACTech, Commander and Hitachi.

The 0-10V uses a common ( ground) wire. Drive it from your bob's 0-10V output. Ground the BOB common to your controller chassis and connect to the VFD input common . That way any VFD noise will go to your Chassis and not thu the bob.

The spindle Fwd can be turned on by a N/O relay, driven from a BOB output defined as Spindle CW in Mach.
Program the VFD to run from a 2 wire start circuit.
