I am trying to figure out the controls connections from AMC to my inverter. My inverter model is Emheater EM9-G1-2D2. It has multifunctional digital input terminal X1-X6 that i can set any of it to REV and FWD function. However I look through the manual (direct download), and i find out there is no switch physically or electronically to change the X1-X6 input terminal to set 24v signal to source. So i am not sure if it suppose to receive 24v or it provide 24v to the X1-X6 terminal. But in the manual it says input voltage range 9-30V (see below)

Love the idea of the no welding build you have !!!! Would be an option for me too, don't know how to weld or have a welder in my contacts :-)
Post video's please !!

it wouldnt be possible for me to weld so this project is made possible for me because of mitch's idea of using T-slot aluminium extrusion but i still think it is more time consuming than welding, because the drilling and cutting the aluminium is not easy task, and need to be very accurate, or you will have more problems during assembling it I have MIG welded and constructed things from steel in the past. Honestly theres nothing wrong with steel for this project. It's driven by material availability, requirements, and personal preference. I opted for the T-Slot extrusion for the upper platform for a number of reasons: - I wanted to use aluminum
- I don't have convenient access to a welder
- For a few reasons, I wanted to keep the weight down
- I wanted to be able to easily change layout if it didn't suit me
- No paint required
- The T-slot material and a seat was similar in cost to a 'playseat' but much more customizable - especially with home made brackets and fittings
- I was able to use the seat framework by itself on the ground while I built the rest of the actual platform from different materials
Sorry, this is turning into a bit of a project post. Maybe I can put together a build post in the projects area some time in the coming weeks. I always intended to make my design freely available (it's pretty simple), and maybe even in kit form if there's interest. I'm sure a few of the other people on the board would do the same. Everyone seems to do something a little different, different materials available, different skill sets, different requirements, but we're all just variations on a common theme. -Mitch

But in the manual it says input voltage range 9-30V (see below) Looking at the schematic, it indicates that it needs to sink the inputs to the ground to activate them. So the default setting on the 6dof ext board is not compatible. However there are two solutions: 1: use relay (there are some cheap arduino relay boards on eBay for up to 16 ports) 2: replace the power chips with ULN2803 and change the two jumpers to the location for that chips so you can sink the inputs of the VFD. I have some example links for both solutions that will place here when I get access to my pc (on mobile right now). Thanks Thanos

Thanks Thanos Hi thanos, Which of this is correct or neither? 1) 2) sorry if the blue wire is ground, the 24v PSU connection is coloured wrongly

Thanks Thanos

Thanks Thanos So i ll try this diagram The sentence in box below, i am not sure if the inverter circuit "GND" can accept 24v ground Maybe i should only try this after confirmation by you. I dont want damage the precious AMC1280. 2) Is there any benefit that can weigh down the added cost of using relay switch like you said earlier compare to method above? Thanks

in the picture is 5v 16 channel relay, does it matter if it is 5v or 24v? Signal from your 6dof extension board for amc1280 is 24v right?

Is this diagram safe? It needs 5v DC 160ma power to both boards = 320ma. Is that enough from the board itself? If using external power i should be using 5v PSU but then i would not know how to sink it, because there is no COM terminal like in your video. Would it make any different if i connect a powered USB hub to the board AMC1280 USB port? Sorry for my poor understanding on electronics. I am using the solid state relays instead of usual electromechanical relays because i read that SSR has lower latency and silent switch. But i couldn't find an affordable one more than 8 channels. Here is the link to actual product
Here is link to the solid state relay specifications

Here is link to the solid state relay specificationsYou can use separate power supply to power the solid state relay boards, but make sure you wire a ground connection from each back to amc1280usb (or 6dof ext board). The connections you made are fine, except you don't need to connect all the COM of all the VFD together, only every two for Fwd and Rev. Thanks Thanos

Thanks Thanos Thanks thanos, i did not noticed the ground connection mistake on the VFD side. And sorry for the big images probably cause your mobile some bandwidth. I find PNG files are large, so next time i will post JPG files only.
