Hi All, I been away on business so I haven't made any progress lately. I am glad that some have found this thread helpful and if there are questions that where not answered please let me know. billo2404 ...Paul was having a number of problems with EMI/noise and I was getting to the point of testing and was hoping to avoid his problems. So I followed what he had done. Now that its up and running the caps on the 24v is most likely over kill but the ones on the position sensor are probably a good thing to include and they really don't cost much. I am no expert on the subject but it is covered in detail on his thread. Trip Rodriguez ...There are definitely ways and lowering the cost and I would suggest shopping around. I would say the numbers I posted should be thought of as worst case. Anyway I hope to finish up the remaining details on the build log next week and will post another video with some closeup details that I think might be helpful. Cheers, GA Dawg

grazie per le risposte ragazzi. Mi piacerebbe migliorare la sincronia nei movimenti che a volte si fa sentire un po di più e altre volte meno. Niente di eccessivo ma se si può perfezionare proverò. Pensi che possano essere utili i condensatori per questo problema?
thanks for the replies guys. I'd like to improve synchronization in the movements that sometimes you feel a little more and sometimes less. Excessive anything but if you can try to perfect. Do you think that could be useful capacitors for this problem?

If you have an oscilloscope then you can check how clean the signals are and eliminate that as a problem.
sounds more like software, AMC or vfd parameters you need to adjust but I have not started tuning my sim yet (soon!) so I am guessing.

Hi GA -
Love this thread, can't tell you what a big help this will be for me when I (eventually) start building my rig.
You mentioned "with blueprints" in the header. I'm new to this forum so I didn't know if there were attachments somewhere or if the description and photos are meant to serve as the blueprints.
Either way, awesome stuff! Was just trying to get all the "dummy proofing" I can get.
Thanks again,
Clayton

@ga-Dawg Again, I thank you for making this thread good sir.
I looked through the whole thread (but didn't have time to read every post yet) and didn't see anything about the actual 220v house wiring to support this project. This is something I'm planning to do very soon, can you tell me what gauge wire was used to run from the main breaker box in the house to the boxes containing the six 20A breakers (in my case located at the other end of the house where the motion sim is)?
Do you have one, two, three, or more cables running from the main box to the motion sim breaker box(es)? Three wires per cable correct? Am I correct in thinking this wiring (house side of breaker boxes) does not need to be shielded for EMF?
Our plan is to purchase the wire and boxes and get everything set up (we are experienced with typical house electrical work), then have an electrician acquaintance come in and hook it up at the main panel end. Dad (an auto mechanic who built and wired the entire house I grew up in; gotta love those old timers!) was thinking three 12 gauge three wire romex cables with two 20A breakers each might be reasonable but we aren't going to work off a guess.
I tried an online calculator and if I understand it right we should use: 2 cables with 3 20A breakers on each: 4 AWG (4/3) or 3 cables with 2 20A breakers on each: 8 AWG (8/3) or 6 cables with 1 20A breaker on each: 14 AWG (14/3)
PS- We need to run the wire 60 feet from the main breaker box to where the motion sim will be. Looks to me like running 6 14 gauge lines will cost about half as much as running two or three larger wire lines! About $150+ for lots of small wire vs. $300+ for less of the big wire.

Go to the first page of this thread and search for "6dof.zip". It is at the bottom of all the pictures in the first post.

Power was a big worry for me also at the beginning but if it helps im running 6 x wj200-015's on 1.1kw motors (next size up from ga).
Each is on its own 20amp MCB BUT the whole supply goes through 6mm SWA which is fed through a 40amp MCB.
Been testing platform all week with no tripping issues so basically its pulling less than 40 amps at load. if your using 0.75kw motors you will be fine on the above.
Main switch is a 45amp cooker switch off ebay.

@ga-Dawg By the way, where are you located in the world if you don't mind my asking?

"So 40Amp breaker feeding just that one cable, 20Amp breaker for each inverter at the sim end of that cable. The 45 amp cooker switch goes where in the circuit, source side of the 6 20A breakers? "
yes thats how i have mine wired. your cable run is not very far, mine is almost double that and you are using smaller motors and vfd's than i am.
If you are set on complying with regulations from an insurance purpose then you will need multiple runs of cable so that the whole supply handles 6 x 20amps!, In my setup my vfd cart is not classed as a fixed install so as far as i understand its fine. and it is safe, there are multiple failure points protected by mcb's and rcds.
Only use swa if you need to (ie extrenal run) its a pain to work with, costs more and cant handle as much amps. if your run is all internal then forget the swa and go with non armoured.

Hi All, Just getting over my jet lag. @paul....Thanks for digging that up. Interesting that he is at .5 Accel and Deccel. Trip Rodriguez ....I ended up running (6) 14/3 wires (will take some pictures this weekend and at to the thread) in a small subpanel. They are not shielded and I haven't had any problems. From my testing you will not even come close to the 20amp (that is the max the VFD will draw). On the other question I live in the US...Georgia to be exact. @clayton ....If you did not find it here is the link

"@paul....Thanks for digging that up. Interesting that he is at .5 Accel and Deccel." YES! i think that is similar to the ramp Steve is using also? there seems to be two schools of thought here, have VFD's set as low(fast) as possible and control speed from AMC end. or have VFD's higher(slower eg 0.5) and have AMC set faster, Ive only tried vfd's fast, amc slower so far and motion can be quite violent at times, hoping to experiment more this weekend, and get some videos. Live for Speed allows motion on replays so just setting that up so i can record whilst a replay is running which will be good for recording and also helpful for me to see tuning adjustments. its getting fun now "I ended up running (6) 14/3 wires (will take some pictures this weekend and at to the thread) in a small subpanel. They are not shielded and I haven't had any problems" Yes from all the EMI reading i did it seems you don't need shielded cable for incoming power, only outgoing, mine isn't shielded either. Most of the noise comes from the switching/output side of the VFD's i think. Whilst on that subject i was browsing through the Wj200 manual again last night and came across this setting that no ones seems to have mentioned before and may be really helpful for us to maintain a nice clean loop: A016: Analog input filter Range 1-30, default 8spl

Our house is loaded with regulations violations thanks to my father (now 89 years old) having a do-it-yourself attitude and no regard for over-regulation. Everything is safe, but building codes be damned! Nevertheless, it would be a good idea to keep a non-fixed classification. I was about to ask what the requirements are for that but you are outside the US anyway aren't you? As for the SWA, I'm glad you mentioned that. I thought maybe you used it due to EMF concerns or something. Trip

Hi All, I have updated the Electrical part of the thread. Word of caution as I am still finalizing things but I am happy to report that I have got LFS and Race 07 working so I should be able to finish up the this post soon. If you are new to reading these threads I know there are some things that don't make sense (at least they didn't to me) and they really want until you get to that part of the build. I am mainly refereeing to the codes in the VFD and how those codes will interact with the AMC. Cheers, GA-Dawg
