Chip ID on a Waveline DC6000 controller

[aaronpentz]

Im trying to figure out a way to control my Waveline DC6000 pump with my apex

This is the gen 2 style pump and isnt wired the same as all the others. I have a spare controller that I can sacrifice if i have to.

I have taken it apart and it seems like its a brushless dc motor with 3 phases. Much like the R/C stuff. Now I could buy a brushless ESC from an R/C store and try it but I would need a High Voltage one and they run a little expensive to just try and see if it works.

My thinking is to use the current board just change the CPU or attach an arduino to the signaling pins and then use that to run the pump. Ideally I would like to just re-program the CPU with different code to just enable an analog in on the chip if it has one.

I have attached a couple pictures one of the front of the board and one of the back. Im having a problem identifing the CPU chip to get the data sheet to see if any of this is worth it.

Anybody out there able to help with getting a data sheet.







Thanks

Bump. Any EE people around here able to help with the data sheet

LOL-I'm no EE but I tried. I dug around for info on it, but everything I found was written in Chinese. Found plenty of "sellers" but no data sheets worth a damn, once they were translated into English.

That's pretty much the same info I came up with also. Thanks for looking

don't know if this helps anymore

not sure what is what you will have to check with meter one is 24v+ the other is 24v- and the other is 0-5v control voltage

Based on the photo of the board, that is a BLDC controller allright. The FETs on the back of the board are a dead giveaway.

Don't discount using an R/C BLDC ESC just yet. I am attempting the same thing for a Maxspect Gyre (using a R/C BLDC ESC). I found some reasonable priced ones from China (~$12) that are able to do 24V. That is what your pump uses as well?

I am just waiting for the parts to arrive, and then I can provide feedback on how workable it turned out for the Gyre, and if it is worth trying for the DC6000 v2.

I am guessing (the chip) is a Chinese FPGA. If you wanted to use this board, how about trying to interface into the header for the buttons/display? It would be crude, but at least the Apex could have some control over it.
