a123 systems MBB BMS CAN
Any one have any CAN communication Information for the a123 16s MBB boards? I powered it up and the light blinks and I don't see any can messages. This is the manual but I don't have a dbc file. I Just want to tell them to balance. https://drive.google.com/file/d/1uF9laYJx3iCORNxymsQENeuiZHse48os/vi...

Re: questions about the sine cosine chip as5116
what chip and magnet combination did you end of using? I'm struggling to get a good signal from the evb90380 with mx90380 chip @ 3.3v.

Re: bldc Mystery Motor foc?
I got a little confused so resolver polls is 1 for sin/cos but polepairs is actual motor. I counted 10 magnets that would be 5? I did have a nice wave on the scope. I'm Using MLX90380 on 3.3v I need to re check my midpoint. thanks

Re: bldc Mystery Motor foc?
So I'm using default setting from wiki. I have voltage configured running 90v. I have set manual id as high as 200 and all I get is noise and a light bit of cogging but no rotation. On sine I get rotation but with max throttle I only get a very slow rotation. I have udcmin corrected. Also swapped ph...

What is my best options? I read foc is not efficient. Also had an arm to move rotor in and out of windings. if anyone ...

Re: Gen 3 dual board small udc not reading
could not find my nice power supply. So I improvised with one of my chargers. I'm happy to report the udc reads correctly when supplying the -5v from the power supply. Current was set to .050 ma. Thinking it was a defective 2776. Thank you uhi22 ! Great idea with the power supply. https://i.ibb.co/6...

Re: Gen 3 dual board small udc not reading
Will do.Thank you everyone for your help. The lm2776 let the smoke out during yesterday’s test. I’m waiting on a replacement. I’m going through the caps and I will check the 50 pin one more time. I’m just glad the inverter outputs pwm.

Re: Gen 3 dual board small udc not reading
I had a lot of problems with my PCB from jlc. I had a failed capacitor and resistor on 26v line so far so I’m not surprised. I will look through the schematics again thanks for the input.

Re: Gen 3 dual board small udc not reading
udcgain 5 and udcofs 0 Default from wiki I get udc resting at 133v with 0v or 80v connected to the hv no change on plot during precharge. Is 80v too low?

Re: Gen 3 dual board small udc not reading
I think some thing is going on with ic17 with the 2276. It doesn't start when every thing is pugged in but works when everything is unplugged. I have hvil bridged but I don't believe its used anyway? I built the wrong board for my inverter so it is missing 2 screws and a ground screw near the ic17. ...

Gen 3 dual board small udc not reading
I have played with gain and offset. I have -5v. I have triple checked the 50 pin under the microscope. When I connect 80V to the invertor there is no change in udc. Inverter does work and spin the motor during testing. I fear there is some thing wrong with the inverter.
