STM32 MCUs Motor control

I am trying to use RS-485 bidirectional half-duplex with automatic data direction control to communicate with an application generated with MC Workbench. The problem is, the response from the motor control application is too quick to respond before the data direction control can switch from send to receive. So I loose the reply data from the motor control application. Is there a way to delay the response from the motor control application?Test setup using Nucleo-F303RE and Nucleo-IHM16M1 with serial communication class described in UM1052.Thanks in advance.

Hi, I'm trying to use both position mode and torque mode.​I saw a comment saying when the position control is activated on a motor, the speed and torque control mode cannot be used.If so, can't it also be switched by turning the position control mode off and turning the torque mode on?​​The thing that I want to purpose is when the motor receives position information through modbus protocols, it performs position control, and when it receives torque information, it executes torque control.(not using both while the motor activating)​If there any solution that I can activated and deactivated the position control in software?any help is much appreciated.​P.S. I don't know if it's necessary, but this is the development environment I'm currently using.NUCLEO-F303RENUCLEO-IHM16M1MCSDK v5.4.7​

We're currently starting with a motor project where sensorless zero-speed startup with max torque will be highly beneficial.I found that there's an algorithm from ST called "ZeST", though I can't really find any relevant information on that.When will this algorithm be available? Where can I find information about its specifications, usage and implementation?

 I am New for this domain(embedded systems), Currently i am doing robotics for some Motors(stepper, DC Servo, pumps and DC geared Motor), Now i started to writing the code for Alternate current servo motor. Herewith i have attached the reference of motor and driver,I am using this type of servo is lifting up and down motion. whenever i run this servo motor at same stepper motor is also not working, but one by one working fine, These codes i have modified from the stepper motor code. The stepper motor is controlled by working in half mode. The servo motor is controlled by working in full mode.Please find the attached main file, CPP file and main file.Kindly help me on this issue.

I installed MCSDK 5.4.8 and CubeMX 5.2, which runs, so, if it uses Java, a suitable version must be installed.But when I try to Generate from a MotorWorkbench project, it gives me this error:Generation process failed. The embedded JRE was not found. Please check the correctness of installation.How do I fix this problem? [I assume I can't just install any JRE willy nilly] 

I have an issue when using both PWMs generated by timers TIM2 and TIM3 to control two motors simultaneously. Specifically, when I call the function DC_MOTOR_Init(0), it activates PWM1, and when I call DC_MOTOR_Init(1), it activates PWM2. However, if I call both DC_MOTOR_Init(0) and DC_MOTOR_Init(1) simultaneously, they don't seem to work together. When I call either function alone, it works correctly, but when I attempt to call them simultaneously, there is an issue. Despite the fact that the two timers do not share common resources.. #include "main.h"#include "DC_MOTOR.h"void SystemClock_Config(void);static void MX_GPIO_Init(void);int main(void){HAL_Init();SystemClock_Config();MX_GPIO_Init();DC_MOTOR_Init(1);DC_MOTOR_Init(0);/while (1){}

Hey,i have B-G431B-ESC1 board and Maxon motor. I can not profile this motor. I want to run my motor at 2000rpm max. Speed and 14V voltage source.The MC workbench is able to generate code. I am able to compile and program it using cube IDE.  i can connect my Board on ST Motor Profiler without Problems.Using MC workbench 6.2.0, the motor profiler tool can't be run : after modifications and tests, the motor does not always run. I can't profile him either. It gives error like it take too time..... it's so frustrating. Does anyone have an idea for me? I need advice!!!!!!   

The MC_ProgramSpeedRampMotor1 api is created in six steps to modify the ramp; however, ramp changes cannot be made with this api.It is possible to modify the ramp in FOC by using the MC_ProgramSpeedRampMotor1_F api.Additionally, two produced APIs are supplied in FOC; however, in the Six Step, just MC_ProgramSpeedRampMotor1 generated.I am unable to modify the ramp using the MC_ProgramSpeedRampMotor1 api in six step. Could you please assist me? Is there another method to modify the ramp in a six-step algorithm?

I have a X-NUCLEO-IHM07M1 and a BLDC motor.BLDC motor have a encoder AS5047P, ABI interface.first, I just connect encoder pin:A to PA10;B to B3;I to B10;secondly, change the speed sensor to quadrature encoder, and generate the code;i just get a error:"Main speed sensor is set to the Quadrature Encoder sensor, but the motor doesn't support it"is X-NUCLEO-IHM07M can not support AS5047P?this is 5047p infomation:https://ams.com/en/as5047p

What is the maximum electrical drive frequency that the ST provided firmware can achieve with the STSPIN32F0B IC?  And/or maximum RPM for a 5 pole pair motor?And the same question for the STPIN32G4....For a target frequency of about 1.5 kHz, what would the recommended PWM frequency be?Thanks to anyone who can assist! 

Dear Sir/Madam ,I am currently using MCSDK 6.1.0 for generating BLDC motor control project for various type of BLDC motors in both FOC mode and HALL sensor mode operations.  Today I have tried to regenerate an existing BLDC motor control project  in HALL Sensor mode using MCSDK 6.2.1 for the evaluation board EVSPIN32F0251S1. I have build the project in ST  Cube IDE 1.14.1 and downloaded the code to the evaluation board. Then I have tried to start the motor in speed mode using ST Motor Pilot program. I have no problem in communication with the board. I made several trials , the motor starts moving  but  I got   over current, over voltage , and mostly speedfeedback faults. The same thing happens with MCSDK 6.2.0 also . The system under test draws high current from the power source during the start-up phase when I  start the motor. It seems to me , high side and low side mosfets activated at the same time.I have no problem with same projec

I am working on a three phase motor inverter with a logic board powerd by the STM32F429VITx MCU and my goal is to run code generated with the ST Motor Control WorkBench on that board. When I create a new custom inverter in the WorkBench Board Manager and set the Parameter  "mcu": "STM32F429VITx"my new inverter does not appear among the options in the WorkBench, so I assume it's not supported yet by the WorkBench to generate a project for STM32F429VITx.Here I found, that all STM32F4xx MCU's are supported by ST MC SDK, but apparently ST MC Workbench only supports generating projects for a subset of them. In the Release Notes for X-Cube-MCSDK 6.2.0, these are the supported MCU's:How can I create a project using STM32F429VITx, if I can't start in the WorkBench?Is the list in the release notes for X-Cube-MCSDK 6.2.0 the complete list? Why is e.g. STM32F417IG listed twice? The selection of this subset of the STM32F4xx family makes no sense to me.

Hey,i made a PCB using STSPIN32G based on the schematics of the EVSPIN32G4. When I turn off the current sensing, the motor rotates normally. When I apply current sensing, the motor doesnt rotate.Did somebody have a similar problem and knows how to fix it?

I am currently going through the documentation of the Board Manager.What was not clear to me is the difference between the Phase Voltage Generation settings DrivingHighAndLowSides and PoweringHighAndLowSides.It does not help that the latter doesn't have an example circuit shown like the others.

[VERSION]: MCSDK 6.2.0[TOOL]: MC WB,[DETAILS]: PWM output Abnormal [EXPECTED BEHAVIOR]:M1 & M2 should drive independently & smoothly[HOW TO REPRODUCE]:1.Profile M1 & M2 by Motor Profiler with EVSPIN32G4. M1 & M2 got Hall .2.Use MCSDK 6.2.0 with EVSPIN32G4-Dual to generate project(default setting, just modify Motor Hall );3.CubeIDE compile the project & Flash into EVSPIN32G4-Dual.4.Motor Pilot to start M1 & M2.=====first start M1 spin well.... Then spin M2-----Can see M1 stop with high frequency noise.5.Try to spin M2 & M1 separately------Works well.6.This EVB should be able to Drive 2 motor at the same time ,but how ?

I am making a BLDC motor controller using STM32G0 microcontroller. The commutation technique that I am using is SVM. But during the initial start, the motor is not rotating properly (vibrating back and forth), It can be seen in the following image which is current waveform taken on a phase. The motor had 3 jerks when the waveform was captured, which are shown in the 1, 2 and 3 sections marked in the waveform. After that, the motor starts rotating smoothly (as seen in section 4 of waveform). When no load is on the motor, it starts smoothly.How to smoothly start the motor?

Hello,I have a small PMSM that I hooked up to the X-Nucleo-IHM16M1 board and a Nucleo-F303RE MCU board.Btw.: Since, for me, with the MCSDK 6.x, nothing seemed like in the documentation or the youtube videos, nothing worked at all or gave any hints as to what's wrong, I have now installed the MCSDK 5.4.8 version, which actually allows me to select my boards & flash according control firmware on the MCU, profile the motor, and create a Motor Workbench project from that.There are some hints already in the profiler, of something not being optimal, but my basic understanding of this technology is not enough to tell whether this could be a reason for the "sometimes works" problem:The profiler notes that things are "optimized for" Rs > 1Ohm and Ls > 1mH. According to the datasheet, the former should be satisfied with the given 1.01Ohm, but the latter not, with only 0.32. But the profiled values are very off from that, giving 0.55Ohm and 0.09mH.It's the 200188 here: https:/

I am using the Embedded Coder Hardware Support Package for STM32 F7xx based development board (Model Settings > Hardware Implementation > Hardware Board: STM32F7xx Based) for my model of implementing Field Oriented Control (FOC).When I run the model using 'Monitor and Tune', it builds the model but at the end, it gives the error that: 'XCP internal error: timeout expired'.All the peripherals are configured in both the Simulink file and STM32 CubeMX file but after it builds the model, at runtime it gives this 'XCP' communication failure error. I followed the three links given below in order to resolve this issue, but it didn't work:https://www.mathworks.com/help/rtw/nucleo/ug/signal-monitoring-parameter-tune-xcp-on-serial-nucleo.htmlhttps://www.mathworks.com/help/rtw/ug/external-mode-simulation-with-xcp-communication.htmlhttps://www.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/External-mode-PIL.htmlAlso, the communication of F767ZI board with STM32 Motor Control

I'm just getting started with the above kit - first step was to reprogram the board to blink the LED! Now I'd like to controlling the motor. I see instructions to reprogram the .bin file, but I was expecting to see an example program with source code - am I incorrect to assume this?

Hi all!I hope you are well.I am currently doing a project which needed a configurable ESC for a brushless motor, with the B-G431B-ESC1 along with the MC Workbench looking perfect for this, and works well when connected to the PC using the MC-Pilot software. It doesn't look to work with a PWM input, even when enabling it within the GUI, with only a very minor reference in the B-G431B-ESC1 of using an external PWM Input. Reading online, I have seen others having similar issues, but with limited success in finding a solution. Along with this, there is a potentiometer built onto the ESC, but the setting to use a potentiometer as input is greyed out due to "not being supported on the hardware", which looks like it could need fixing! Don't mind a script-based rather than GUI solution if needed!Would love to hear any thoughts, as I would certainly like to use this combination in the project, with a great balance of cost-effectiveness against flexibility and performance.Many thanks,WB

I can use the Motor Pilot ok but when I try to connect with the motor profiler I see a momentary connection when left in "polling" mode where the B-G431B-ESC1 board flashes on screen, then the board disconnects and the image disappears.  Here's the logs:[INFO] - : Connecting to Board [INFO] - UART worker: Successfully open port COM3 @ 115200 [INFO] - : try to configure the board [INFO] - : Connected to board [INFO] - : Disconnected from boardWhen I try to connect in non-polling mode I stay connected but no board appears and all the buttons are grayed out.   Just now I confirmed that the Motor Pilot is working again.  Then I disconnected with Pilot and reconnected with the Profiler.  Now the Profiler program allows me to click on "Start Profile" but that results in an error below:[INFO] - : Application is starting : MotorPilot version:1.2.5 [INFO] - : ini file path=C:/Users/COSMED USER/AppData/Roaming/ST Microelectronics/ST Motor Pilot.ini [INFO] - : Pollin

Hello, I'm trying to use my B-G431B-ESC with the 6-step algorithm. I''ve tried with a coupld of profiled motors and what happes is that it starts up fine, but after ~2K RPM, the motor starts to squeel and lose power. I feel like this has something to do with the back EMF sensing... Has anyone got the B-G431B-ESC working in 6-step? Are there any tips for tuning the BEMF parameters?Thanks BTW, I've tried playing with all the BEMF parameters, and other things like the modulation frequency and other parameters but it still starts to break down above 2kRPM (increasing the modulation frequency helps a little bit, but not nearly enough).  Motor control workbench Version: 6.2.0STM32CubeMX Version: 6.10.0STM32CubeIDE Version: 1.14.0Controler/Driver: B-G431B-ESC1 kitMCW application: Electronic speed control on B-G431B-ESC1 kit (6Step) Working, right before 2KRPM Squeeling starts, right around 2KRPM: 

I generated some code with the default "Electronic speed control on B-G431B-ESC1 kit" project in Motor Control WorkBench.  Then when I flash the default code I get a HardFault when calling `__HAL_FLASH_PREFETCH_BUFFER_ENABLE()` in  `HAL_Init()`:int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); ...

I'm trying to use the dev kit to run a BLDC motor in sensorless mode using the default MCW project.  When the motor starts up I hear a high pitch chirp and then the firmware repeditively tries to spin the motor which results in more periodic chirps.  Here's a link to a video: https://drive.google.com/file/d/1Gm4Ks_ejrTA_0d9IWSSXPMtr5tzbqC_3/view?usp=sharing MC Workbench v6.2CubeMX version 6.9.2CubeIDE version 1.14.0 The only other thing I tried is changing the pole pairs from the default 2 to our motor's 12 pole pairs.  

I can't seem to download any software from the ST website.Whether it's the MC SDK or even just the STM Cube programmer. The download button is there when I'm logged out, but all the links disappear once I log in. Alternatively, if I request a download link to my email I never receive anything, even after waiting hours. This feels like a very silly issue so I hope it's resolved soon. Thank you! EDIT: The download started working almost instantly after I made this post. Not sure if it got fixed or just coincidence, but I'm glad it works now. Thanks
