Is anybody try to start MG1 and MG2 power stages in parallel with six jumpers SJ1-6? How connect three phases outputs? If I connect in parallel to regular outputs, then MG2 current will be measured with regular current sensors, but MG1 current sensors connect to Arduino and MG1 current stay not mea...

Hello. I have read over and over the CAN message mapping description but still can't achieve a thing. There is this command: can rx canio 300 0 5 32 where I understand 300 is ID and 32 is scaling whatever it does. What is 0 and what is 5? What this command does? Where is the actual CAN message that ...

Ok so the original UVW encoder is responsible for providing the speed of the car to the speedometer. At first I thought it was the wheel sensors that report the speed but I was wrong. Good that I chose to leave the original encoder in place and mount the sin/cos encoder on top of it. That way I can ...

Regarding throttle pedal signal. I tried feeding the throttle pedal +5V and ground from a separate source and I only fed signal wire into accelerator input on gen3 prius inverter but this did not work. So it is necessary to power the pedal from the openinverter board also in order for the throttle p...

RLS encoder you need to select according to the pole count! This is really important so let them know your motor parameters in a comment or message. I think your encoder will be P/N RMF44AC01SA10 and magnet you will select RMM44A3A00. See their online store. https://www.rls.si/eng/rmf44-rotary-magn...

https://i.postimg.cc/PJcfP4Qs/Screenshot-20201201-231516-Samsung-Internet.jpg I've got a throttle pedal that one of the channels gives 0.389 v at rest and 2.064 v fully pressed. The other channel I did not manage to get any reading out when pressing the pedal so far. I'm not sure how to enter the v...

SavvyCan To help me with CAN diagnoses, I have bought an Arduino Due that I'm setting up for SavvyCan. But this is proving to be more challenging than expected. I can't get the sketch to run properly - it won't spit out anything to the serial terminal. So that needs some work as well. [update: this...

SIG 1 Throttle at rest: 0.73V Throttle at full travel: 4.00V SIG 2 Throttle at rest: 0.36V Throttle at full travel: 2.02V Note on the connector: It's a Tyco unit (expensive) but there are nice cheap clones available on AliExpress - search for 967616. Hi. Mine has got exact same connector and I got ...

Long phase cables ring tremendously. Also there are losses in that. You can bring DC power towards inverter wherever you need it, but phase cables... just saying. You're right. I did some googling apparently that is an issue with variable speed drives. Can damage the motor and the leads. However I ...

Well Crap!!!!!!!!! Openinverter FOC Tuning. i have drove my self crazy. i hate guess work. wrote down wiring connections for the Prius Gen 3 to the P314 transmission for my electric mazda, now after finding the exciter wiring and resolver wiring, i now have tried over 16 different combinations for ...

Cant you mount inverter over the motor? Phase cables need to be as close as possible to motor. Long phase cables ring tremendously. Also there are losses in that. You can bring DC power towards inverter wherever you need it, but phase cables... just saying. I did not know this either, thanks! It is...

Ok, definitely no resolver They mention various feedback devices I think we found out it is in fact a UVW encoder and all 3 phase leads were fed through one hall effect current sensor in the original inverter for that motor. Encoder has 3 signal wires that seem to produce 4 pulses each per full mot...

3m cable seems a bit much, cant you use shorter cable? If you cant go past that be extra carefull to rout the cable far away from DC and phase cables! Since I have to run the cable to the middle or the back of the car where I plan to mount my inverter I'm not sure if I can make it shorter. I was pl...

Well you need to make 44mm recess in your mount center. Make it like 2mm deep with central hole so that when you mount your bolt in center of shaft it will almost touch the underside of RLS metal pad. https://i.postimg.cc/pXdFnjhL/20201128-220300.jpg Unless Johannes is willing to make a software so...

So, before we go down the modifying path, is there: A) A hardware method to convert this to something more useful to the OI board? B) A software method to understand this signal in the OI software? I'd say it's definitely desirable to not mess with things that have tight tolerances unless absolutel...

Be aware though you need to use nonferrous bolt. Best use aluminum. Also try it first without magnet so you can devise a sort of locking mechanism. Maybe a counter nut? And when you work with RLS plate be sure to make an interface board that will let RLS slide directly into center. Thanks, I overlo...

https://i.postimg.cc/0jLb2Gjt/20201128-105957.jpg This is the connector of the encoder. Inside the lead with 5 wires 1 out of 3 signal wires is visually smaller. I was hoping it might be the Z wire. I have made the led test. I connected 5 v to vcc and ground and i attached led to a ground wire and ...

First lets see the number on encoder. Which number? That is very interesting, should I try pulling the entire encoder out and see if we can make anything out? The connector is pictured above. It was plugged into the original inverter the motor was used with (OEM vehicle, entire drive train made by ...

Hello, I will try to start this thread both hoping for help and guidance and also to serve as documentation and testing ground in trying to use openinverter software in a gen3 Prius inverter using ABZ encoder. This encoder comes installed in a permanent magnet synchronous 8 pole motor made by Leroy ...

it would be good to test the output on the A and B channels to see how many pulses per revolution they show. Or maybe you have encoder PN written on that PCB? I am interested seeing what would that motor do with ABZ. Is it ACIM or PMSM? How would I test this? I've only got a multimeter. I don't yet...

try taking it out of the motor and posting a picture https://www.linkpicture.com/q/20201125_201652.jpg https://i.postimg.cc/QxbpnCnZ/20201125-201539.jpg https://i.postimg.cc/cC1JKx7f/20201125-201601.jpg I tried pulling the thing out, feels like pulling internal shaft out of the motor, quite large, ...

Those values are way out of range, I'd say open circuit. Resolver must be a couple of 10 Ohms. And again, if anyone contacts me directly without sending some funds along with the question, I consider this rude. I don't owe anyone because I published a design. This must be some type of encoder then?...

Help! According to data sheet I have 3 phase synchronous permanent magnet motor with 8 poles. Apart from 3 phase wires I have 9 other small wires coming out inside two separate leads. One lead has 4 small wires (which are a touch thinner than the wires in the other lead) and the other lead has 5 wir...

https://github.com/latonita/arduino-canbus-monitor Above is the arduino sketch and libraries that turn arduino and mcp2515 into a socketCAN useable device (using can232/Lawicel protocol). Same wiring of nano and mcp2515 as for canhacker software. It is necessary to set the correct can bus speed in t...

Are you able to read CAN from the car at all? After excruciating 3 day effort trying 4 laptops etc I was able to get SavvyCAN software to run on exact same setup like yours - arduino nano and MCP2515 can bus shield. And it was actually very simple when you know what to do. It only works on a comput...
