DDSCV1.1 3 and 4 axis offline motion controller

I must admit a little confusion from this thread.

It all stems from the definition of perpendicularity. I thought perpendicular meant 'at right angles to a plane' i.e. the XY plane, so the thread was referring to the Z axis.

Reading it again it seems more about XY squaring, which makes a lot more sense. I do no see how any software could compensate for a cutter out of tram moving up and down at any angle other than vertical unless the cutter head was spherical and the shaft small enough to allow it to miss the sides of the cut.

Im slightly confused too, if i dumb it down for myself - does he mean if he went to cut out a rectangle he would actually get a parallelogram?

I would guess that !

Ok i am really struggling to get my DDCSV1.1 to activate my spindle Via the Huanyang VFD, has anyone on here already done this successfully? I'm not sure on, and cannot seem to find any information about what signal the VFD is expecting on the FOR terminal in order to engage the spindle.

Any help would be greatly appreciated.

Thanks

I think all is self explaining from manual:



Only 3 cables you need. Ground is connected in the VFD as far as i remember

Hi,

Yes i figured it out. You have to wire it as the manual, however the VFD is slightly strange as you have to ground both the ACM & DCM (Analogue & Digital Grounds) to each other. A bizarre occurrence to me, not sure what the Chinese logic is behind it but it works. I can now control the M3/M5 commands and set the speed from the DDCSV1.1.

Hey Alex.

Just wanted to thank you for this post, as I was struggling to get my Huanyang VFD to run at the speed I am setting from Aspire.
I managed to get it turning on and off at the start and finish of a job all ok, but the speed setting didn't work and it just ran to max.
Connecting the DCM and ACM together via a simple wire fixed it, so thank you.
