Wiring Diagram check

[cropwell]

Jazz, when looking at my VFD manual, it looks like instead of the FWD (which is actually labelled FOR) I should use the RST pin.. If I wire the FOR-DCM loop through the relay, the spindle will start automatically right ? I'm not sure that's the behaviour I want.. I just want to be able to manually control the start/stop speed etc with the VFD front panel, but automatically stop when the relay goes off. I know you're gonna end up thinking I'm dumb, but I promise I'm not that stupid haha :) Now, if using the DCM-RST loop, I guess it would have to be normally closed, so that when nothing's powered the spindle does not start, when the relay is on the RST line is off so the spindle can start/stop as I will, and then when power goes off (due to pressing the e-stop) the relay goes off and the RST line closes which stops the spindle.

What you could do is use a two way switch with centre off. One way would switch the FOR-DCM directly and the other would put the FOR-DCM through a relay controlled by the BoB. That would give you three modes :- Fully ON,Totally OFF and Automatic. I do this for my Kress spindle and also my chip blower. I will probably do the same when I build the next machine with a VFD controlled spindle.

Cheers,
