STM32 MCUs Motor control

I use MCSDK v5.4.7 and STM32CubeIDE 1.6.1. Project generation with MCSDK is successful but when I try to build code with the IDE it ends with fatal error "sto_cordic_speed_pos_fdbk.h: No such file or directory". Run code generation with an other example project works well. So I asume that my tool chain is okay.

Hi.I am trying to communicate with AS5600 Position Sensor. We are using I2C communication for this purpose. Using STM32F439ZIT6 chip , running chip at 168 MHZ clock. We are sommunicating with the sensor at Fast mode 400000 speed. Connection seems OK while there is no problem. But somehow when HAL turns error we lose alot of time to recover. At our main loop our cycle goes up to 50 ms ( tickresult)  while trying to recover. Can you help me what I am doing wrong and what could be the source of this time loss.  HAL_StatusTypeDef I2C_ResetBus(I2C_HandleTypeDef* hi2c) { GPIO_InitTypeDef GPIO_InitStruct = {0}; // Configure SCL and SDA as GPIO outputs GPIO_InitStruct.Pin = MOTOR_SDA_Pin | MOTOR_SCL_Pin; // SCL and SDA pins GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_OD; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; HAL_GPIO_Init(MOTOR_SCL_GPIO_Port, &GPIO_InitStruct); // GPIO port B // Generate 9 clock pulses to release a

Hi,I am trying to run a 3-phase BLDC motor using the DRV8323 driver in 1xPWM mode with a Hall effect sensor. I am also using the Nucleo WB55RG board to generate a 20kHz PWM signal.The motor is spinning, but there is audible noise, which decreases only at a 50% duty cycle. Additionally, the motor speed does not vary with changes in the duty cycle.INHC= HIGHINLC = HIGHINHA = PWMINLA,INHB,INLB = HALL sensor

MCSDK 6.3.1, FOC with STOPLL, EVSPIN32G4, this motor.We're using a custom board based on EVSPIN32G4 as a drone ESC in a traditional sensorless configuration. Naturally, in our application the motor starts up to a low RPM under idle load and then after FOC takes over it spins up and down within the whole range as commanded by the autopilot. The MCSDK is in the speed control mode.We have found an interesting fault condition (also recreatable with the original EVSPIN32G4): if the motor is held in place somewhat elastically, e. g. by hand, during startup, the following things might happen:Speed feedback fault flag is set ~45% of the time -- expectedStartup fault flag is set ~45% of the time -- expectedNo fault flag is set, the motor is not spinning (sometimes making noises), the indicated RPM jumps to very high negative numbers, followed by speed feedback fault after a few seconds -- unexpected, but easy to catch and handle, RPM flips are easy to see.No fault flag is set, the motor is

Hello Everybody,MCSDK:6.3.0CubeMX: 6.3.0Workbench : 6.3.0Motor Pilot : 1.2.9Power Board : IHM08M1Control Board : NUCLEO-G431RBMotor : BL5702I am now using Motor Pilot to adjust the speed. Below are part of the settings from Workbench:a) Speed Sensing Selection : Observer +PLL(Sensorless)b) Speed Sensing Config / Auxiliary Sensor - Speed Sensor Mode : Hall Sensorc) Drive Settings : Open Loop OFFd) Applicaion Configuration : Motor Profiler(Enable)I followed the steps from STMicroelectronics/MC_SDK_6.3.0/Documentation under the Motor Profiler section. I started with Workbench to generate the project -> CubeMX GENERATE CODE -> CubeIDE to flash and run the program.However, I noticed that the program gets stuck at TSK_HardwareFaultTask();. This prevents me from testing my Hall Sensor with Motor Pilot.If I disable Speed Sensing Config / Auxiliary Sensor - Speed Sensor Mode : Hall Sensor and reflash the firmware, the program runs without issues. But when running Motor Pilot, I encounter

Hi everyone,I'm trying to run my BLDC motor to its maximum torque and speed limits as specified in the datasheet. I’ve increased the supply voltage, but the motor still won’t reach these limits.Details:Using [motor/controller model, e.g., "IHM17M1 and Motor Control Workbench"].Motor performs well within rated limits, but I can’t exceed them even with higher voltage.Questions:Why isn't the motor reaching its datasheet-specified maximum limits?Are there specific settings in [software, e.g., "Motor Pilot or Workbench"] I need to adjust?Could controller or firmware constraints be the issue? Any guidance would be greatly appreciated!Thanks!

I am trying to output a 3-phase PWM waveform with a phase difference of 120 degrees using one timer with STM32G431CBU6 and simulink. Can you tell me the detailed settings of stm32CubeMX and simulink?

Dear all, I am developing motor control system, and would like to observer the (motor) current response.  In the past, the method I often used was DAC, where the current command and actual value were output separately through the DAC to an oscilloscope for monitoring. I have also used UART/RS422 to send the data to a PC and then plotted it using Excel or MATLAB. However, it was insufficient to reflect (motor) current data in real time. My current control frequency is 20kHz, but the communication update rate can only reach a maximum of 1kHz, even with a baud rate of 921,600 bits/s. (It can only be used to monitor speed response at best.) I wnat to build/implement a communication and it can enable me to observe a data with 20KHz update rate. This helps in diagnostics and analysis of transients. So, I would like to ask if anyone has any experience or suggestions.Currently, I am using the STM32H563 as  MCU. Best Regards,  

I have tried connecting both STLink and UART but Motor Pilot is not getting connected, ERROR: No STLink VCP detectedI am using (V1.2.9) and tried using older version but still issue persists. Kindly help.

Hi Is there any way to define a ACIM custom inverter?I have only 2 choices : FOC & 6-Stepwhat about ACIM custom board definition?Thanks.

Hi every oneI have defined a custom motor and inverter successfully.Now I need to define custom features like a simple Digital output(LED for instance).Is there any way?or should I cut working on stmcubemx and continue coding after code generated by workbench. in other words:Is there any way to modify workbench generated .ioc file and again generate project file after editing it?(for example after adding a digital output?)Thanks a lot

Hello,I bought a P-NUCLEEO-IHM002 kit and am creating a C code in MCworkbench 6.32.However, I am getting an error during creation and can't compile it, so I want to check if there is anything I am missingFor your information, I attach the file created in MC workbench 6.32.I want to change the code with P-NUCLEO-IHM002 kit and make it work. Thank you for your cooperation in advanceSY

Hello Everybody,MCSDK:6.3.0CubeMX: 6.3.0Workbench : 6.3.0Motor Pilot : 1.2.9I used open-loop voltage on the motor pilot to perform tuning with (voltage_ref, TargetSpd) at the following settings: (10%, 300), (20%, 600), and (30%, 900), each with a duration of 2000, to check the motor's operating condition.However, when I used the API for tuning, only (10%, 300) operated normally. When I updated voltage_ref to 20% and set the Speed to 600, the motor struggled to rotate (it was jittering).My question is: during the rotation process, do I need to stop the motor before calling OL_UpdateVoltage and MCI_ExecSpeedRamp? or I should use others api to change the voltage_ref and the speed?

Hi, I am using the P-NUCLEO-IHM03 STM32 motor-control pack along with a AMS AS5147U rotary sensor for speed control with Hall-effect. The rotary sensor needs to be calibrated by setting a zero angle aligment. This is done by disconnecting the motor from the motor driver board, and connecting UVW to an external power supply. We then apply a current to the motor, resulting in locking the rotor in a fixed position and reading the angle from the rotary sensor. This angle is now treated as zero. Does anybody know how to use the MC SDK to force a UVW pattern so that we do not rely on an external power supply to lock the rotor? ThanksRoar

I have STM32G030C8Tx C project that I am trying communicate with BigTreeTech TMC2209 module with the UART half duplex interface. I have attempt to write the code from scratch, kicked that around for a few weeks, gave up and tried to port over some ardiuno projects. I have finally a working project on github, https://github.com/veysiadn/tmc_2209. Still haven't had any luck. I have two drivers boards that I am working with. One I have soldered the bridge pads on the bottom, the other has no modifications. Drivers have tested on BTT SKR 1.4 turbo board with marlin configured to use UART, both worked.   Both boards have the pot adjusted to give the boards enough current at 12 volts.   Both power supplies are running for testing the firmware.I thinking it may be a wiring issue, maybe? The code...USART initialization  static void MX_USART2_UART_Init(void) { huart2.Instance = USART2; huart2.Init.BaudRate = 115200; huart2.Init.WordLength = UART_WORDLENGTH

Hello everyone,I have an existing project on the STM32H753VIT6 and I need to add three-phase motor control (FOC mode) via STDRIVE101 driver. The question is whether my approach to importing the MCSDK into my project is correct.Due there is no support for my MCU in MC Workbench, I choose NUCLEO-H745ZI-Q and generate a project for it. (also I choose A2212 13T motor and X-NUCLEO-IHM09M1 bridge).As far as I understand, STM32CubeIDE desn't have possibility to automatically import the configuration from H745 to H753 (?). Therefore, I need to configure the MCU myself via CubeMX, or transfer partially the contents of the .ioc file of the generated H745 project to my one (however it is not recommended to change this file).But look like in order for "Motor Control" to appear in "Middleware and Software Packs" in "Pinout & Configuration" in any case, it is necessary to edit the .ioc file and add following: ExtraMW=MotorControl ExtraMW.MotorControl.Config=MotorControl ExtraMW.MotorCo

Good morning.I am running an IHM03A1 stacked onto a Nucleo - WB55RG.  I am finding that if I send the commandBSP_MotorControl_CmdSetParam(0, BSP_MotorContorl_SPEED, (uint32_t)speedMotor);followed by BSP_MotorControl_GoTo(0, pos);the motor will not move the first time the GoTo command is called.  All variables are valid and I don't believe it has anything to do with waiting as I am stepping through code in debugger so there is plenty of processing time for the PowerStep.  If I call the GoTo command a second time without any in between motor commands the command works.Ideas?

As my understanding, ST890 used for isolate USB 5V and Battery 5V( DC/DC from 10V by U12: LDFPVR ). And also provide 5V for ESC board in debug program even  without battery connected.But why when I use battery only, which means no usb pluged, there is still 5V in stlink board. (D3 led is lighted.)  SEEMS st890dtr transfer output voltage 5V to input side. (U5V) IS THAT A ISSUE?  

Hello,[VERSION]: 6.3.2[TOOL]: Board Designer, MC WorkBench[DETAILS]: I created a custom board, created a new project and generated the code. All fine.I opened Board Designer and changed the crystal frequency on the board. I saved board Json file.I opened my project in MC Workbench and generated the project again.[EXPECTED BEHAVIOR]: New selected crystal frequency should be shown in STMCubeMX-Clock Configuration/.ico file, but is still the old one.New selected crystal frequency should trigger source code change in SystemClock_Config(), but is still the old one.Thanks, 

Hey I was I wondering if it was possible to use the x-nucleo-ihm08m1 on an 144 board.I only have 144 pin boards but couldnt find my board on MC Workbench.I also tried the motor pilot software and it said to configure the board.I suppose I can use it but without the MCWorkbench,am I correct?

Hello everyone,I am using MCSDK 5.Y.2 with an STM32G431RB MCU on a custom board. I can successfully run the motor using the three-shunt topology. However, when I switch to the single-shunt topology, the motor does not start.I checked the mc_api.c calls for both configurations, and they are the same. On the single-shunt board, I immediately get bState = FAULT_OVER right after bState = START. This issue does not occur with the three-shunt board.When generating the motor code, I noticed some differences in the file structure:For the three-shunt topology, the directory MCSDK_v5.Y.2-Full\MotorControl\MCSDK\MCLib\G4xx\Src is created, containing the file r3_2_g4xx_pwm_curr_fdbk.c.For the single-shunt topology, this directory is not created, and instead, the file r1_ps_pwm_curr_fdbk.c is placed in the Src directory. Was r1_g4xx_pwm_curr_fdbk.c removed on  MCSDK5.Y.2?Could I be missing a difference in the state machine or configuration between the two topologies?Below is the code

We're using a driver that inserts a deadtime by hardware.It is not clear to me how I have to configure that into the MCWB firmware to get ADC measurement working properly.I see three deadtime-related settings:- "minDeadTime" property in the "PhaseVoltageGeneration" feature of the Motor Control Boards Description- "deadTime" property of the "DrivingHighAndLowSides" HW variant (this reads like this is a fixed deadtime inserted by the PWM timers)- "SW dead-time" setting in the FOC wizardI couldn't find a proper documentation for any of those.What do these values do?Which of those settings is the correct one for my case?

Hello,first of all, I would like to thank STMicroelectronics for their commitment to providing information and expertise to the public free of charge. Currently, I am working with a very competent study colleague to set up a test bench.We intend to operate a PMSM with the mentioned 5KW inverter. It seemed like a simple project at first...The motor identification was performed using an IHM08M1 setup. The electric machine spun wonderfully! :)Now we have set up a complete test bench with the mentioned board, the ICS current sensing board, and a Nucleo-F446RE.After generating QC and settings to make the machine spin, we cannot get the electric machine to run!After several hours, to be precise, we tried somehow to get the Motor Profiler running.Ultimately, we saw in the MC Workbench that this function is only possible when the current from all three phases is measured.The STEVAL-CTM008V1 "Current sensing board" was, of course, expanded for the third ICS, but in the board manager (JSON file)

I profiled my motor using the Profiler application while it was not under load. Afterward, I used the obtained values to generate new software. However, during testing on the motor pilot application, the motor does not start under load, regardless of whether it’s in torque mode or speed mode. When it’s not under load, there are no issues. Do I need to perform PID tuning?here are videos under load and not load https://youtu.be/hOYXae-8l-M?si=RV6EAJ2st8wsGWhUhttps://youtu.be/sTGa2zcNCKY?si=5_LyxKUZ59Qp4z13  • The Profiler application cannot obtain values when the motor is under load.

Hello,I'm going to buy Nucleo-446RE and IHM08M1 board and do FOC position control.I'm going to analyze the code and practice using the ST Motor Control SDK.For questions, I would like to receive a recommendation for a motor that can be programmed without purchasing an additional speed sensor among the PMSM motors on the ST Motor Control SDK.Is it only possible to operate with the Incremental encoder when I don't know the initial Pole location?Please recommend B.regardsSY
