STM32 MCUs Motor control

Hi, I have encounter a problem when I connect esc001v1 to st motor control workbench monitor through UART. I couldnt connect to ST motor control workbench using UART but I can connect to st motor profiler using UART. I am using SDK 5.2 and IAR workbench IDE to download the program into the esc001v1. So is the problem exist in hardware or in software? Anyway to solve this?

I'm a newbie in motor control. I'm working on STSPIN32F0A for control a 24V BLDC motor.It was very simple configure e control the motor at different speed (2900 to 3400 rpm) with no load. I've got only some measure(rpm / phase current / torque / power abs. at load, and at no load) about the motor given by manufacturer, but also LS , RS, Ke, Ki. When I try to add load to my motor, speed begin to decrease at values below the setted one. Why motor doesn't stop for speed feedback error? and why at certain power absorption value is the motor speed low than what manufacturer say? thanks

Hello All,I am using the Motor Control SDK and Workbench with the Nucleo F446 evaluation board and X-Nucleo IHM07M1 motor driver board, together with a PMSM 8 pole servo motor.The issue I have is that when I set the torque ref (Iq) to > 0 and flux ref (Id) to 0 in the advanced tab of the workbench and press "start motor" the rotor fixates in the same way as in the alignment phase. When I turn the rotor shaft by hand it "snaps" into position at regular angle intervals.To check for encoder and current measurement problems, I inserted some debugging code into the FOC algorithm to dump encoder position, Iq and Id values. This is a result from the debugging, where you can the rotor fixating and Iq and Id settling on their commanded values.

Why can not use the HFI function in SDK5.2.0? But I found the file hifreqinj_fpu_ctrl.c in the lib.

I have installed MCSDK_v5.3.3 on my Win10 machine. I open example project P-NUCLEO-IHM001-BullRunning.stmcx, save it in a new folder as suggested and click the Generate icon. The "Project generation" finds all my installed STM32CubeMX (4.27.0, 5.1.0), I select "ST SW4 STM32", "HAL", FW V1.10.0 (Recommended, not installed) and press the Generate button. Generation failes immediately saying:"Deploying MotorControl Pack version `5.3.3` to D:\Users\Frank\Documents\STM32Cube\Repository\MCSDK_v5.3.3\MotorControlUnable to deploy MotorControl reference pack to D:\Users\Frank\Documents\STM32Cube\Repository\MCSDK_v5.3.3\MotorControlMotorControl reference pack not found: "../../../../Middlewares/ST/MotorControl"Completed with errors"Well, there is such a folder, but it is one "../" level off:C:\Program Files (x86)\STMicroelectronics\MC_SDK_5.3.3\Utilities\PC_Software\STMCWB>dir "../../../Middlewares/ST/MotorControl

I am developing a motor controller with version 5.3.3 of the MC SDK.In the Basic tab of the Monitor, there is a Motor Power (W) indicator:It has an upper limit of 200 Watts.On the Registers tab, the same info can be seen:My question is, where does this upper limit come from?The software is configured for motor nomi

Hi, dear all!I am curious about the current functionality of FOC SDK.I checked that in ST Motor Control Workbench does support over voltage protection and a brake resistor can be used to dissipate the power.But I am curious about whether or not the motor can work in torque mode, and continues to produce a resisting torque, dissipating mechanical power and converts to electrical power.like a negative Iq configuration?thanks for reading this post!Zt.

In our application, we need a PMSM motor to run mostly in torque control mode.However, we also want to have a RPM limit in certain operating conditions.With the FOC library v5.4.0 (running on a Nucleo-F302RB), I coudn't get this behavior to work.In torque control mode, the speed limits MOTOR_MAX_SPEED_RPM and MAX_APPLICATION_SPEED_RPM are both ignored, and the motor spins up to the maximum speed possible by the DC bus voltage.Does the library support a speed limit in torque control mode?

Hi,I'm working on a project trying to port an old FOC SDK 4.0 based application on a new MC-SDK 5.4.0 one. The job is done on a STM32F407ZE board where previously the use of FOC 4.0 allows to spin a brushless PMSM motor at various mechanicalspeeds. At the moment the motor supplier is not able to tell us if the motor heis selling us is a SM-PMSM or an I-PSMS motor...From a MC SDK point of wiev, our motor application uses a 3-phase inverter basedon three STM L6395s (High voltage high and low-side drivers) and a 3-shunts currentsensing configuration.No over current protection mechanism is at the moment employed and the currentsensing is based on external opamps whose configuration has been taken from another HW application note (this was the job of an external HW engineer).Speed and position feedback is obtained employing 3 120-degrees shifted phase Hall sensors; neither PFC or Brake

Hi, I'm a fans of STM32, i can write my code under linux well. But know, i wanna use adv motor control, i know ST has a MC SDK, but it for windows only?i hope i can design my motor program on Linux.Thank you !

Dear community I have purchased a STEVAL STM3201 spin kit,After getting the data sheet for my motor the motor is nearly spinning it is so close.Eventually I will use halls but to walk before I can run I will try sensor-less firstI have used the motor control workbench 5.4.3 to generate the code from a template using the en.STSW-SPin3201. Im using atollic true studio code compiles without errorsI take a project and a default motor template SDK5x - STEVAL-SPIN3201 - BullRunning.stmcx then I change all the parameters to suit the motor I am using to do this i follow UM2152 manual line by line.The motor nearly starts It connects to the motor work benchI kept getting error FOC Duration every timeSo I changed the parameter pwm frequency from 13,000 to 5,000 line #define PWM_FREQUENCY 5000// 13000in the file drive_paramaters.hrecompiled major improvement the FOC Duration error now disape

Hello everybodyI'm using MotorControl Workbench and Motor Control SDK 5.4.1.I need to control some power tools up to currents of 40A peak. I developed a board similar to IHM08M1 and I'm very satisfied of the power delivered to motors. There's only a "little" problem: I should improve the behavior at heavy loads when motor has to startup, because I noticed that in this case it fails to start. I've a linear ramp of 750ms in which motor moves from 0 rpm to 1650 rpm (15% of nominal speed at free load) and the final current in this phase is the nominal current (so the max current we can give to the motor).Could be a practical solution create a phase in which current rumps up very quickly to nominal value and desired speed moves from 0 rpm to a little value in a brief time? After that phase I would add a phase in which current is still constant at the maximum value and speed moves from the previous little value to the 15% of nominal speed to exit from open loop mechan

How I can programming MCU (Example code with description, PID control, use STM32 Motor control SDK5.0, Motor control workbench and others)? Where is video example, AN?

Hello colleagues! In the process of working in FOK SDK 4.3 with the controller STM32F302RE, I had several questions:1) When using the HFI mode, I can not configure the control settings. Perhaps you have some kind of guide to configure each parameter.2) When I start the engine with an encoder, the shaft cannot rotate at a speed lower than 6 revolutions per minute, that is, 5, 4, and so on, the motor just holds the moment. I also noticed that in fact the speed changes stepwise at 6 revolutions per minute. How can I make the speed change in steps of 1 revolution per minute?3) Tell me how to properly configure the PID controller for Iq and Id? By changing these values, the engine begins to behave differently.Thank you in advance for all those who responded.

The steps to reproduce: Uncompress STSW-Robot-1, import EVALKIT_ROBOT_1_SDK543_Positioning_LL.ioc using all default options. Answer ‘Yes’ to “Open Associated Perspective?�?Project Manager Settings appears, informs that “The Firmware Package required by the Project is not the latest version available in your STM32CubeMX Repository�?, I press the default option to continue with the slightly outdated software. Workspace comes up, and I click build. On build, the first error I see is: ../MotorControl/mc_stm_types.h:37:12: fatal error: stm32f0xx_ll_dac.h: No such file or directoryLooking at the initial unzipped file structure, that file is included. Somehow importing into STM32CubeIDE is removing some files. Can you please provide instructions on how to properly build this example?

"Can't Add: MotorControl files not found"This above is the error I get when I try to load an existing project using STCubeMX V5.6.0.My toolchain set up works on my laptop and I attempted to duplicate the same tools on my work computer. Both are Windows 10 64-bit and I made sure to use the same tools versions of STM32CubeMx V5.6.0 and STM MC SDK 5.4.3. I zipped and copied the project workspace from one computer to the other. I am using the Keil IDE and on both computers I can load the project and do a build-all without error.The STM32 Motor Profiler and STM32 Motor Workbench both launch and run okay. I'm only having an issue with CubeMx loading an existing *.ico file.-Thanks

Hi,I am develloping a system using the motor control sdk. I am usiung the ‎STSPIN32F0‎ chip and the following software versions:This module only has one ADC peripheral and I need to use it in my application. Looking around, I have found that the Regular Conversion Manager (RCM) might be exactly what I need for this situation. I can see in the release notes that this feature was added in the 5.2.0 version:

Hi,I'm try to use example provided by ST - EVALKIT_ROBOT_1_SDK543_Positioning_LL.After few little correction the project (i.e. modbus was added to project using absolute path, not relative using project location), example is working, but:1.On the start, motor sets 0 position (I'm reading this position using function MC_GetCurrentPosition1()) and motor stays at this position. But if I rotate motor by hand over 20.5 radians, then motor suddenly run in this direction and stops at 40.84 radians. I can do it once more time, in the same direction, and result is that motor stops at 82.03 rad, and so on. When I do the same thing to 0 position direction it returns with the same few steps and returns exactly in 0 rad pos.2.The example configuration STEVAL-ROBOT-1 us very low current, something 0.07A.Do You know, how to fix those issues?Lukasz Lecki

I succeeded in operating the Tartget Motor with STEVAL-ESC002V1.However, since the STEVAL-ESC002V1 is not linked with'Motor Profiler 5.4.4' SDK, it is impossible to check the motor operating speed.​I know that STSPIN32F0A has a function that can measure the motor speed.​Does the STEVAL-ESC002V1 have the ability to measure the RPM of a motor like any other motor Eval Kit?​Or can I read RPM information with UART?I have not modified the firmware of the'STSW-ESC002V1' you provide at all.Please help if there is anything that can help with RPM measurement.If the experiment is successful, STSPIN32F0A will be applied for mass production in our equipment.

Hi!I'm working with custom HW built for sensorless control of SM-PMSM. I've adopted MCSDK library to run it and tuned controllers + observers to achieve most of my requirements. Performance is quite good, but occasionally the motor just stalls (at startup or due to unpredicted load), while still pretending "ramping up" to desired speed. I would describe it as the observer got fooled recreating angle and speed from its own setpoints not from the current state and blindly drives the output further and further just buzzing the motor.Missed something in the SDK?I though that this probably is one of the typical limitations of current sensorless algorithms and i cannot do anything with that / must live with that / give up some of my requirements. But maybe i missed something and does anyone know of some "gotcha" or met similar problem and dealt with that / knows the cure? Could it be easily solved by some settings?Possible solutio

hi sir i am using motor control workbench generated foc sdk and running motor of 6 pole bldc successfully but in my application of motor heavy load is given on motor so it indicate over current fault so please guide me to by pass overcurrent fault from generated code no matter rpm goes down
