STM32 MCUs Motor control

Hello, I am very new for ST mc. I want to use evspin32f0602s1 for BLDC motor,I have generated the code using Workbench,STCubemx and finally code seen in IDE,but I dident getting what to write in main() function ,how it can handle any fault situation and how i will send parameters like Voltage,current and frequency serially using RS232,please help.

A motor control project, 240826-FAN-40A-48V, have been generated by Motor control Workbench-6.3.0 for the custom board based on the STM32G431RBT. Because of error 'Attr not supported : Dmpu' during generation, the project is imported by CubeIDE. I am not sure why the Project name on the Project explorer is 'STM32CubeIDE' instead of '240826-FAN-40A-48V'. Then I need to add other functions using USART3 and some GPIO Port. Firstly 240826-FAN-40A-48V.ioc on the Project explorer is clicked to open it. But I got a message on the screen as;    "Invalid Input: Must be project's active .ioc file.     Project's 'STM32CubeIDE' active one is 'STME2CubeIDE.ioc' file"     But I could not find the 'STME2CubeIDE.ioc' file in my project directory. Because of above issue run the CubeMX and Load '240826-FAN-40A-48V.ioc' then generate the code. Now open the project but I found that several mc_ files have error mark on the file name and the contents of the file looks like

How to enable Hardware Flow Control in STM32 Cube MX , because when I am trying to enable it - conflict with ADC1:IN6 . I want to enable Hardware flow control RS485. I have attached the screenshot of the issue being faced. This program is generated by STM Motor Control Workbench. I haven't changed any parameter.

I am trying to generate code for "STM32 Nucleo packs FOC and 6-step motor control platform for three-phase, low-voltage and low-current motor" and I keep getting errors :-Attr not supported : Dmpu  as in attached image. I am using cubeMX12, I have updated Java recently and I have uninstalled and reinstalled CubeMX as well. Still no luck. Log file attached. 

I'm using MCSDK 5.4.5 in a high torque BLDC application.DC bus voltage: 600V, motor power: 4kW, Hall sensors, current sensing with two insulated current sensors (7mOhm).I had the effect that the motor power, returned by the API, switched to a negative value when increasing torque.I have detected an overflow of the 32-bit variable wAux3 in the method PQD_CalcElMotorPower() in the file pqd_motorpower_measurement.c with my setup. If Iq is large enough and other factors such as PQD_CONVERSION_FACTOR are large as well, an overrun error occurs in the calculation.By changing the order of the calculation, I was able to correct this effect.I am now afraid that such an error can occur in other places in the code...Question: is there a possibility in the MCSDK to adjust the scaling of the variables to fit on a high powert application?

I'm trying to implement 6-step BLDC commutation with an STM32F767 MCU, commutation table shown belowI have the 3 hall effects going to GPIO interrupt pins, the ISR code is pasted below. I used the generated code from the X-CUBE Motor workbench as a starting point for how to properly enable/disable the PWM lines. void EXTI15_10_IRQHandler(void) { /* USER CODE BEGIN EXTI15_10_IRQn 0 */ /* USER CODE END EXTI15_10_IRQn 0 */ if (LL_EXTI_IsActiveFlag_0_31(LL_EXTI_LINE_13) != RESET) { LL_EXTI_ClearFlag_0_31(LL_EXTI_LINE_13); /* USER CODE BEGIN LL_EXTI_LINE_13 */ /* USER CODE END LL_EXTI_LINE_13 */ } if (LL_EXTI_IsActiveFlag_0_31(LL_EXTI_LINE_14) != RESET) { LL_EXTI_ClearFlag_0_31(LL_EXTI_LINE_14); /* USER CODE BEGIN LL_EXTI_LINE_14 */ /* USER CODE END LL_EXTI_LINE_14 */ } if (LL_EXTI_IsActiveFlag_0_31(LL_EXTI_LINE_15) != RESET) { LL_EXTI_ClearFlag_0_31(LL_EXTI_LINE_15); /* USER CODE BEGIN LL_EXTI_LINE_15 */ /* USER CODE END LL_EXTI_LINE_15 */ } /* USER CODE BEGIN

Hello.I am using a B-G431B-ESC1 Board with an Quadrature Encoder. I have already managed to drive my motor using speed control and position control. But why is it that, when you activate "Use absolute position control pin (ENC_Z)" in the MC Workbench, you can't choose torque control or speed control anymore?  Thanks for your help.Losi

Hello,I am designing FOC motor controller based on DRV8316. For this, I am adding a DRV8316 custom board in the MC Workbench. Please find the JSON file attached. The problem is that I am unable to add phase voltage sensing. Although I have added phase voltage sensing in the JSON file it is not appearing in MC Workbench.Thanks   

In my design , MCU controll 8 sets of  STEP MOTOR  .    Every MOTOR  has  A / B Encode pulse outputsIN CubeMx  Six timers (TIM1-TIM5  & TIM8  )can be configured to ENCODER MODE 。  But  How to implement the other 2 Motors decoder ?   Can we use gpios ? 

I tried to modify the serial port, but the baud rate parameter was not successful.Use STLink to run the code online, observe the serial port reception, and there is data received.But after the pilot prompted the above picture, the serial port was closed. What shall I do?

I would like to have a firmware example for EVLDRIVE101-HPD.Do you know where I can find firmware examples for this board?

Hi, I've been using my custom board with the STM32C011G6 MCU as a control board. By customizing the JSON file on the power board, I've been able to generate a project through MC Workbench -> CubeMX -> CubeIDE, and the motor driver has been running well. However, a new revision of the custom board requires me to reroute my UART pins to PA9 and PA10. Since the STM32C011G6 doesn't have standalone PA9 and PA10, I need to remap PA11/PA12 to PA9/PA10. Unfortunately, I don't see this feature in MC Workbench. Directly assigning PA9/PA10 in the JSON file results in the GUI indicating that the UART feature is not supported. How can I resolve this? Thanks.

Dear all, I always encounter a "Over Current" fault once I click the "Start" button.I have traced my phsae current by current probe, but it is shows less than 1A.I have no idea what problems it is, has anyone can resolve it?I list my platform and configuration as follows:1. Motor Control Workbench 6.3.02. CubeIDE: 1.15.13. Control Board:NUCLEO-H563ZI4. Power Board:X-NUCLEO-IHM08M15.

Hello ST,I’m a motor control fan and developed a few motor controllers in the past years for myself. I always worked with TI MCU’s because I liked their sensorless solution for PMSM control. At low speed the torque generation was not bad but at zero speed, there were some problems. I always started with HALL sensors and at a certain speed I switched to sensorless FOC.At the moment I’m building a 300A 100V motor controller for my master thesis and I wanted to use a sensored solution because of the startup problems with sensorless solutions. Then I saw your ZEST algorithm, which looks very interesting.Now I’m wondering if the ZEST algorithm could solve these startup problems, what do you think?Can I replace the encoder with ZEST without having any problems at zero speed?I’m using a 20kW BLDC motor which is inside a buggy car.Best Regards,Daniel

Hello,I'm using the Motor Profiler tools v5.Y.3 to try to profile a hooverboard BLDC motor (15 poles pairs, 24V, low speed typically 300rpm), with a Nucleo F401RE + IHM08M1 setup.After having found a configuration for the hardware that made the motor spin:Capacitors C3, C5, C7 removed on IHM08M1, for FOC mode according to UM1996Solder bridges J5 and J6 on 3sh side according to UM1996Resistor R181 removed for Motor Profiler according to Motor Profiler's hint 'Remember to configure correctly the board..."Jumpers J9 open, JP1 and JP2 closed for FOC according to the hintWhen I start the profiling, the motor starts to spin few seconds, then stop, then restart, etc... until it systematically triggers a "Speed feedback fault" when the speed reaches about 1/3 of max speed, and restarts from scratch the electrical profiling (and fails again, and so on). So the profiler never completes the electrical identification.At higher speeds and torques setting, the motors sometimes starts to oscillate (v

Hello there,I've encountered a problem when running motors with the F0 and C0 families. Perhaps this is already a known limitation, but I thought it still deserves a post.I don't need this to be solved, as I won’t be using these controllers for my particular project, but it could be a bug, so I figured posting this as a bug report might be a good idea.Hardware setup:NUCLEO-F030R8 / NUCLEO-C031C6 / NUCLEO-G431RB / NUCLEO-F401REX-NUCLEO-IHM11M1Custom SM-PMSM Motor: 7 pole pairs / 1.2 Apk / 0.11 Ohm / 0.018 mHSoftware:MCSDK 6.3 / 6-STEP Algorithm I'm setting up the project through MCWB, and the only changes I make in the project are the REV up parameters and setting up MotorPilot to enable open-loop control. The generated project has a PWM frequency of 50 kHz, and yes, I know that's way above the recommended 10 kHz for an F0/C0 board. However, I have tried altering the PWM frequency to 10 kHz and 25 kHz, among others, and the problem still occurs.The problem:When I run the motor on t

Hello everyoneI am having a problem when I turn on SPI to display the LED, at the same time I start the motor but it does not start successfully, it gives me FAULT_OVER error. While I turn off SPI and no display, the motor starts and runs normally. I have tried to find a solution but cannot solve the problem, with my lack of full understanding of the motor control program.I hope someone can help me with this problem.Thank you very much for this help.

Hi Community, I am starting to learn brushless motor control. I studied the brushless motor principle and tried to use MC WorkBench 6. One thing puzzled me a lot is that why there is no BLDC option in MC WorkBench, only SM-PMSM and I-PMSM. I know that BLDC and PMSM are pretty much the same in structure, so I can just choose PMSM even if the motor I am using is in fact a BLDC? 

Hi ST Community I used EVSPIN32G4 board and MC Workbench 6.2.1.I configured to use speed mode and hall sensor using EVSPIN32G4 sample project.The motor supports 15V, 16000rpm, and 40mN.And I tested it using MC_FOC_SDK GUI.The following situations occurred.0. If there is no load on the motor, the motor will rotate normally.1. If you hold the motor with your hand before it is activated, the motor will not rotate.2. In that condition, the power of the motor became stronger and could no longer be held by hand (GUI's "torque reference" value was approximately 5A)3. This process takes about five seconds.(too late)As a result, I need strong torque at low speed, but I don't know where to fix the source code.Please let me know if you have any solutions or ideas for this. Thank-you and Best Regards,   

Dear experts, we like to develop new VFD spindle motor controller, with V/Hz open loop control. I am searching for a modern reference design for 220V applications, based on the STSPIN32G4. But I could only find designed for BLDC, focused on FOC, but not V/Hz control. The STSPIN32G4 seem to have everything in 1 chip, including 600V MOSFET driver, except the power stage. So it would just be matter of the Firmware to output a 3 phase variable sine.  Is there a application note or reference design, maybe also for the STSPIN32F0, for a V/Hz motor control? Is there support for CubeMX for this? Inverter motor designs are mentioned many times, just not together with V/Hz. There are older designs from NXP and TI for exactly that, but I want to use the highly integrated STSPIN, also because we are familiar with the STM32 series. Thank you.

I have made some custom register json file which i want to load in my motor pilot but when i go into the motor pilot i dont get the option to load the json file:1. I tried and overwrite and json file which gets loaded by default and i can see my registers in motor pilot BUT there are some registers which i want to write value at which im not able to do.attached is the screenshot   

Hello AllDoes anyone know how to connect X-NUCLEO-IHM08M1 with NUCLEO-H563ZI?I would to evaluate it with MC workbench 6.0.3.  However. I am not sure how to connect it together.It looks like I CAN'T plug it directly, because the slot and pins are not matched. 

Hi,I have emax cf2820 1200kv brushless dc motor and i want to drive it with X-NUCLEO-IHM07M1 motor driver and NUCLEO-G071RB control board. Since the motor I have is not registered in the workbench, I need to import it as a JSON file. Could you tell me what parameters need to be included in the JSON file? Or should I modify one of the existing motors to match my own, even though it's a PMSM motor? Best Regards

Hi there,I'm writing this post because I have encountered a potential bug/firmware issue with the MC firmware versions FW1.11.4/FW1.11.5 for the F0 fam, and I'm unsure on how to proceed in diagnosing the cause of this problem.Background:I want to use a chip from the F0 family to run the six-step algorithm with back EMF sensing for speed and position feedback. I have successfully spun my motor using this setup with a PWM frequency of 50 kHz, utilizing the F401RE Nucleo board and the IHM11M1 evaluation board.As I move forward, I want to get the software running on ANY F0 MCU to begin with. For this purpose, I'm using the F030R8 Nucleo board, (which is availible in the supported boards in the MC workbench 6.3.0) , and have set up a project in the MC Workbench, which can be found appended to this post for inspection in the google drive link. In this project, I've reduced the PWM frequency to 10 kHz to decrease the MCU's workload.https://drive.google.com/file/d/1iH10Fo9dF0ywQuWusjUGKnc

Hi,When I select the 6-Step algorithm in MC Workbench > New Project > General Info the NUCLEO-F302R8 does not appear in the list of control boards. Does this mean the F302R8 cannot implement the 6-step algorithm? I thought 6-step was less computationally demanding that FOC (which the F02R8 can do)?Best regardsGary
