STM32 MCUs Motor control

..

Hello,I am trying to get the STEVAL SPIN3201 to work with my motor but when the board draws at around 1.1A it always reports an overcurrent fault. I tried to change the motor parameters to see if these are the reason but it had no effect at all. After that I also tried to change like every parameter in the drive settings (e.g. cut-off frequency) but it also had no effect.Even when I set the overcurrent protection topology on "No protection" the fault still occurs.I thought the evaluation board should be more or less plug and play when the motor values are right since everything else is given for the board by Motor Control Workbench.Is there anything I can try to make the board work? I could not find additional reasons that might cause the overcurrent fault when the overcurrent protection is disabled. What could be the cause that the board does not work with most of the settings given by ST?

Going over the documentation for the EVSPIN32G4, this is the schematics for current sensing:But starting a project in Motor Control Workbench for this board, seems to have different values for the same schematics:Am I missing something? Why the discrepancy?

Hi all,I'm new to the STM32 MCU familiy, so I've got trouble already doing basic stuff like reading the analog input value of the potentiometer. My main problem is, that I don't understand how multiple measurements can be made on one single ADC. I've watched several Videos about the topic already, but can't get it to wok properly. With some code variants I read bigger numbers that shouldn't be possible with a 12bit ADC (23.000-ish or even bigger), with other codes I dont get anything back at all. What I did so far:The datasheet states that the potentiometer is connected to pin PC3, so I added this pin in CubeMX as a ADC1_IN9 pin. In the ADC1 Mode and Config tab, I didn't change any settings, as I'm not sure if its needed. Only thing I've read in one of STM's MC docs is that I'm not allowed to use the injected conversion mode as it will interfere with the motor controls.In the while loop I added these commands:HAL_ADC_Start(&hadc1);ADC_ChannelConfTypeDef sConfig = {0};sConfig.Channe

Hi,I have to make low cost on BLDC for Industrial Sewing Machine with Three Hall Sensors and read about BLDC from resources available on internet . I have P-NUCLEO-IHM001 for BLDC motor controland seen below youtube video from ST.https://www.youtube.com/watch?v=h3ZuM2Z0UGsIt's based on IAR workbench.How to Start: ?1) How to start with BLDC motor control application with STM32CubeIDE,CubeMX with ST Motor profiler with P-NUCLEO-IHM001?2) Is it possible to generate code for FOC or BLDC with Sensors (Hall) , Six Step Commutation etc. with Software Tool Chain ?3) How to connect Customized Hardware MCU and Drive (MOSFET) board the STMotorProfiler?4) As this board can operate motor the max rating of 1.4 A RMS. How to design hardwaredriver circuit for with Six MOSFETs and Driver circuit compatible the Software Tool Chain ? Any other suggestions ..Thanks in Advance ..--Karan--Karan

I have created and developed a motor control application using the B-G431B-ESC1 development board which has an STM32G431CB MCU. My product board has STM32G491CCU MCU. I went through the process of creating a fresh STM32G491CCU project in CubeMX (and made no changes) and then imported the .ioc file from the development board project. That seemed to go well - no errors but I had to change the ADCx clock from "Async Div 1" to "Async Div 4" because when I generated the code it complained that "Async Div 1" was invalid. Anyway, I continued on and tried to build the project in CubeIDE (v1.7.0). I had to resolve header / include issues to get everything to compile but then I get linker errors. I have verified that the library exists and is in the directory that the linker is searching and I have verified that the functions that can't be found are in fact in the library file.The reason I had to take this path to creating the 491 project is because the Motor Control Toolbox won't allow the 491

I'm looking at different alternatives for PLCs and I would love to use STM32 as one, but it seems like the boards that STM sells are all eval boards or individual boards. I'm lookin for a completed product that has stepper motor control and GPIO. Is there anything out there like that?

Is there an assumption that the motor parameters are for a star connected motor when setting them in the STMC Workbench ? If your motor is delta-connected, then can you put values given in the motor datasheet directly (winding resistance Rs, inductance Ls and back-emf constant, etc) or do you need to convert them according to the figure ?

I'm working on a project where the STMC FOC v4.3 SDK has been used. Developers of the project are not available for support, and I need to learn the details to implement new features as well as debugging/fixing existing code.To facilitate my learning, I've bought a P-NUCLEO-IHM001 and generate code using the new version of the SDK. I'm using Keil and the onboard ST-Link to go into debugging, to look at how the code is being executed and trying to get access to some project variables. Of course, I cannot run the motor and simultaneously have breakpoints in the code. So I'm trying to look at some register values, i.e. the DAC and ADC1 registers. When doing this, the motor is spinning, and the Motor Workbench Monitor says that the UI has connection to the MCU, but pressing the "Stop Motor" or "Execute ramp" no longer works. Also, pressing the blue user button and turning the potmeter also has no impact on the motor.I hope to come across some "How to debug STMC FOC projects", but cannot fi

Hi Everyone. For some reasons, we want to switch the current MCU to STM32H745 in our new generation designs. To make POC, We are trying to generate code for Nucleo H745 example in the C:\Program Files (x86)\STMicroelectronics\MC_SDK_5.Y.3\Projects\NUCLEO-H745ZI folder. So far, unfortunately, We could not achieve code generation. We have tried different versions of the CUBEMX and also different version of the MCSDK software. In total, We´ve tried about 10 combination of that versions. but unfortunately We could not. On the other hand, for STM32G4xx and STM32F4xx series boards, we could achieve. In addition, I tried all steps with my personal computer (w10), but no success.Here is a photo what i meanAlso, I tried all the H7 HAL SDK includin V1.9.1 , V1.9.0, 1.5.0 but no success. So, It will be really appreciated if you help me on this.Best Regards. Samet Kocatepe

Hello,I'm experimenting with the Motor Control SDK toolchain (MCSDK v5.Y.3).I set up the config in Motor Control Workbench (the .stmcx file is attached, I changed the extension to .txt so that I can upload it...)After having check all pin assignments are OK, I generate the project for IAR v8, CubeMX 6.1.1, with HAL drivers type, firmware package 1.25.2. The generation complete without warning nor error.I then open the IAR project that has just been generated and try to build it as-it-is. I got the warning and the error below:Macro redefinition:Warning[Pa181]: incompatible redefinition of macro "SPD_TIM_M1_IRQHandler" (declared at line 173) ***\Inc\parameters_conversion.h 178=> I set a different timer for the hall sensors and for the auxiliary speed sensor (quadrature encoder), but the same symbole SPD_TIM_M1_IRQHandler is defined for both timers:#define SPD_TIM_M1_IRQHandler TIM2_IRQHandler #define SPD_TIM_M1_IRQHandler TIM3_IRQHandlerI expected to be able to choose different timers

We've got code that's been working for months. We updated the HAL Drivers and IDE, and now we got a gremlin. Now we have intermittent hard faults after an external hardware reset, but only when using STMCubeProgrammer (not the IDE) to program the MCU, and seemingly only after a full chip erase before programming. We've instrumented the hardfault handler and we see the attached output when it happens:So two questions. This output looks very strange, especially the PC being at address 0x2000000. I've tested the tracing code with intentional hard faults, and it works fine, so I think this address is real in some sense.Second question - does anyone know how to programmatically generate a call stack from the hard fault handler? I've seen posts using gnu Unwind_Backtrace, but none of them have any explanation as to how anything works.Any help would be greatly appreciated!! We are burning days of time trying to figure this out.

I'm driving 3 stepper motor​ using STM32F030C8T6TR MCU 3 different TIMERS I want to acceleration deacceleration motor so for that I want to change TIMER frequency and count pulses output at chanel how can I do it?Example :Motor travel distance 10000 pulses​SPeed of motor directly proportional to timer frequency.First acceleration slowly increase frequency (1000 pulse), then run at set ​frequency(8000 pulse) , then slowly decrease frequency(1000 pulse) then stop timer So speed curve is slowly increase frequency - run at set frequency - then slowly decrease in frequency according to total number of pulses.​​

I have a BLDC 24v 2.7 v/kprm 1.5 ohm 2.1mH device with a 200 CPR 2 channel single ended incremental encoder. I am using a NUCLEO-L476RG and X-NUCLEO-IHM08M1. I seem to have an issue with some of the terminology used. First the motor control SDK mentions Pole Pairs. The motor datasheet says 8 poles. I assume the SDK wants 4 pole pairs. Would this be correct? Second, the SDK states Pulses per mechanical revolution. Since the encoder datasheet states CPR (counts per revolution), I am assuming the SDK wants 50 PPR since it is a 2 channel encoder with 4 state transitions. Is this correct?The Motor Profiler states that the measurement is taking too long. I have adjusted the speed both up and down and left it blank with the same result each time. What is going on here? Also the electrical model usually has low values for the resistance and inductance. These always seem to be 50% or lower compared to the datasheet of the motor. I have followed the proper configuration of the boards that the Mo

I use Hall sensors as speed feedback, is it possible to correctly start the motor when it is under 100% load.Or need to apply special methods for initial increase in speed like 6-step control?I have attached several oscillograms that I found about this, whether the Motor SDK does it on its own or it has to be written manually separately and then how to combine it with the FOC algorithm.I am using B-G431B-ESC1 board and MC SDK 5.Y.3
