Hey folks, I’ve setup the B-G431B-ESC1 with an old EMAX RS2205 I’ve got lying around that should have plenty of power for my application. I feed it with 15V. The motor has 14 magnets, and my understanding is this means it is a 7 pole pair variant. I’ve ran through the setup guide and both the enc…

[image] Motor Vibrates and Spins Unexpectedly When Using Angle Control + FOC Current in SimpleFOC Hi, the symptoms you described indicate a runaway situation. You also didn’t mention anything about velocity PID tuning. I guess you went from torque-mode to an…

I’m surprised you said the encoder is working? IMHO you have to include and init the “wire” (I2C) interface? Another minor thing is: you use a generic I2C sensor class, but there is a more specific model for the AS5600.

I didn’t need any changes anywhere other than pulling in the class and use it for I2C to work. There’s the 5 pin connector with PB7/8 (if memory serves) that’s available for this. And the test program showed operation.

I just followed the setup guide that suggested testing the encoder, PWM, and then angle mode. So yes, no tuning. But even the calibration move at the start isn’t working at all. I’ll try and upload a video, had some issues with that yesterday.

Hopefully this works: iCloud Photos - Apple iCloud This is the calibration move right at the start. No commands given. Motor gets hot.

For one thing your calibration voltage is too high. I use 0.6V on a 2300kv 2204. Try disconnecting the motor and setting it up to rotate slowly in open loop mode with SinePWM modulation, and probe with multimeter between ground and each of the phase outputs to verify that they ramp up and down. If …

Is calibration voltage the align voltage? I’ve reduced that, and tried setting up a constant rotation. See the current code here: /** * B-G431B-ESC1 position motion control example with encoder * */#in - Pastebin.com The current sensing puts out values like this: -98, -101, -96, -157, -72, -…

I checked all the examples regarding I2C sensors and they all had one line in common: // configure i2C Wire.setClock(400000);

[image] deets: Is calibration voltage the align voltage? Yes. I’m not sure what the problem is, but there sure is one. The values in each row of the printout should sum to 0, and be nice sine waves going positive and negative rather than the mostly-negative chaos here. If my calculations are…

Had a week of work, back on it. Yes, it’s a limiting supply, but it’s at 3A, and while there’s some voltage drop observable, I’m not seeing anything above 1A, so I doubt it is at fault here. I did set the I2C speed to 400K, but as expected that’s not at fault here - I’m reading the angle all the ti…
