Thank you for your feedback! I've just updated the master branch at github, all numbers from 1 - 10 are checked now in the checksum procedere. For your troubleshooting: I think most problems are reported with 12 and 18 FET controllers with high amps settings. Please start with a battery current limi...

OK. Do you have the phase current sensor installed and working?
The advice of apple2 is exactly right. Disable the automatic angle correction and try to find the correct motor specific angle. Swap Hall and motor wires, if you can‘t find a satisfying angle setting.

Can you describe the meaning of „cogging“ or even better post a video?

Today also uncomment line in main.c

You are really brave

With this you put the throttle input directly to the PWM. With no safety feature like battery- or phase current limitation active....

@kkm: feel free to implement all your suggested improvements in our code and present us your result here in the thread.

Perhaps on your way you will learn how a PI-control works and why it makes no sense to test the system with no load / wheel in the air.

I've looked at the svm table and I am wondering what tool is used to generate it? Also would it be more efficient to disable pwm on the low phase? There are several approaches how to calculate the SVPWM pattern. You can't switch off any channel as we are using center aligned PWM. Zero in the lookup...

I released the new Controller firmware M0.16.D and the Java Configurator Beta 0.2.0.

Thank you!
perhaps you can add the link to your githup repo to your signature! I always have to search for it, when I want to take a look at your new releases

I think Stancecoke code does not implement this limit.

Sorry, you are not up to date, the phase current limitation is implemented since several month

Does the standard KT controllers come with a higher Phase Amps than Battery Amps?

This is not Kunteng specific, but normal behaviour of any controller, that uses pulse width modulation for driving the motor.

Code: Select all

Iphase = Ibattery/duty cycle

Hmm, very strange. But I can't help from the distance.

keep the correction (at) angle at 127. Play around with the motor specific angle. Sorry the function of correction (at) angle is not dokumented in the wiki yet.

So it should still be speed throttle, not torque? The throttle controls the current (= torque), that's the "normal" behaviour of every throttle in any motorcycle or car. Xnyle has build in the option assist lvl affects throttle , with this you can reduce the max amps of full throttle for low speeds...

It would be interesting to hear the developers comments on this. I can't follow kkm's arguments, he reported his experience before: Flexible OpenSource firmware works excellently on all my geared motors - Bafang SWX02, MXUS XF15R and XF08. Very quiet, there are no unpleasant vibrations and some res...

How many erpm can a KT controller handle? At the beginning of this topic, casahino was talking about 40k erpm as the maximum, is that value still valid or does the "high motor speed" option allow more? The outrunners I'm looking at are near the 100k erpm zone... The max speed is limited to PWM freq...

The push and pull feeling is a bit annoying afterall. Please reduce values of Gain I and Gain P, e.g. by factor 10 or 100. You can finetune them later, if you have found a satisfying range. if I had installed an external torque sensor to the rear dropout of my bike or to the chains, I could use tor...

Ok. Changed the battery cal a value to 100 and now the battery current and target current match very closely. :thumb: Is the motor still braking that hard, if you stop pedaling? Please try this on the road, as with wheel in the air, it is not representative. Yes. I understood that torgue-simulation...

stancecoke

Current target = -0,2A(314) when standstill, and when rotating freely(pedaling tire at air) current target is 32A. Battery current cal a = 46 Battery current cal b = 314 I think your video is in Torque-Simulation mode with highest assist level?! Cal b seems to be correct. For a S06S Cotroller cal a...

when i started the motor,i could hear the noise maybe the commutation voise and feel the motor shake. with the speed increased,the niose disappered.is it normal? yes, that's normal, as the motor starts in 6-Step mode and switches to 60° interpolation at 3erps. } else if (ui16_motor_speed_erps > 3 )...

Maybe my direct motor hall order is counterclockwise

Don't give up. Try to find the right wire combination, otherwise the firmware can't work properly. (No firmware can work properly, if the wires aren't connected in the right order...)

Hey Hangdog, the Sempu sensors aren't like THUN or TDCM in this regards. They more or less put out a signal whenever there is any kind of force that bends or stresses the spindle. It doesn't matter if it's a forwards torque, a reverse torque, or you just standing on the pedal at the bottom of the s...

marcoq, can you please create a new thread for user support to your branch? Perhaps we could build a Java Tool, that creates the hex-file (e.g. EEPROM.hex) for the EEPROM content and then flashes the file via a batchfile that calls the STVP commandline tool (like it is done for optionbytes and prog...

Hi. Which line of code to remove if you want to program the ZWS controller to work properly?

Just disable the option "Enable rotor angle correction" in the Java tool.

Did you drive by direct drive motor ?when i started the motor,there were some noise and the motor was shaking . then i changed the "motor special angle " as "160"(the best number),but i could still feel that the motor is shaking.are there any parameters to adjust？ I'm using the BionX IGH3 with our ...
