Hi all. Trying to install a vfd driven spindle to my Woodworker. I see that I can use the speed control through the 26 pin D type breakout board (Via RS485) to the VFD, The VFD I have (HY01D523B) does not appear to have the RS+ and RS- connections I’ve read about but has a connection bus as shown i…

Hey David, usually I suggest to Read The Fine Manual… :slight_smile: Welcome to the forum!

Didn’t come with one, and the on-line docs show RS+ and -. Very annoying.

Hey David, Huanyang changing the VFDs hardware / the manual / the specifications without prior notice was frequently reported. A word used in this context is “mess”. The terminals that you show are not like those I have ever seen on Huanyang HY Series VFDs. Good luck!

I found this manual which seems to have the same pin layout for a different branded product. https://cdn.hackaday.io/files/255641093730176/VFD%20ASKPOWER%20A131%20UserGuide.pdf I can’t find any mention of it supporting RS-485. It seems like it may have a RS-232 port.

Hey David, when you say you have an Huanyang HY01D523B, why is it a Isacon ASKPOWER A131 instead? Could you please, in cases of such help requests, post an image of the VFD nameplate, e.g. like here or here or here . That is good practice in hardware support forums. [image] Atroz: I found this…

I’m not sure he can use RS-232. It’s a 12v system vs the 5V of RS-422. RS-422 is half duplex, much faster bit rate, etc… I haven’t looked into whether the Onefinity controller can do RS-232 instead of RS-422.

Hey Atroz, hey David @RedTonto , hey all, here’s the RS-485 interface / Modbus doc at buildbotics . While RS-485 can do full-duplex over four wires, the RS-485 interface at buildbotics uses only two wires. You are right, RS-232 is not compatible out of the box with RS-485. RS-485 – a descendant o…

Hey Atroz, hey David @RedTonto , hey all, according to schematic circuit diagram , Onefinity Controller uses Renesas ISL83485 chip ( Datasheet ).

Hi, There is not and RJ45 visible. See pictures attached. [IMG_4350] [IMG_4342]

Hey David, thank you for providing this information and images! What we can see here is confusing but does not surprise me. It is clear that installing, wiring, programming and using such a complicated device like a VFD witout documentation would be a challenge. I would try to find a manual. But …
