Need Help!- Connecting a breakout board to spindle speed control

[waisberg]

Hi,

I have a Chinese xyz-tech cnc machine. It worked well for 6 months but now the dsp handle is dead. I am planning to remove the handle and use a off-the-shelf parallel port interface like the CNC4PC instead.

The problem is, that I have no idea how their Spindle speed control works. There´s no wiring diagram and no manufacturer label anywhere. I tried to email xyz-tech a couple of times and had no answer. I am asking the cnczone community some educated guesses on what type of spindle control this is and how to connect it to a breakout board...or if there´s any way I can figure this out!

Your help is going to be very much appreciated!!!

Well, xzy-tech removed the spindle inverter label, but there was a sticker with this "DZB 416" on it.

I googled it: most of the results came out "Dragon Ball Z" but some good soul posted a pdf manual of a similar (same manufacturer, different model) inverter. The Chinese manufacturer is Fuling Inverter - www.chinafuling.com - but their site is in CHINESE!

the link with the manual is (the pdf is too large for posting) http://www.cnc-technik-madreiter.at/...r%20manual.pdf

Well, there are 4 wires coming from handler board to the inverter. "s0, s1, s2 and -vc). Any sugestions????
