STM32 MCUs Motor control

Hello,Now I am working on a project for motor control, the MCU is STM32G474VET6, so I started with STM32CubeMX to config. When I config Middleware and Software Packs, there is no 【MotorControl】 software pack. where can I get the [MotorControl] software pack?but when I see a project which is created by motor control workbench6.3.0, the .ioc file opened with STM32CubeMX has [MotorControl], why?Best Regards,dqsh06@Andrew Neil  @mƎALLEm @GMA 

Hi all, I've been trying to implement a system (due to UL requirement for safety) where I need to brake a motor (max rpm=4000). By modifying the Motor Control library I' managed to add braking by overwriting "R3_1_LowSideBrake" to perform a full brake on the motor using the Low-Side Fets. My next step is actually braking the motor only using HW logic. For that I've ORed a switch with CIN pin to disable the motor driver with the hopes I could program the Timer Break to enable low side FETS (by setting the IDLE output of low sides) but without much success.Below is the schematic of what I did. Signals from R509/R510/R511 comes from current sense resistors to detect the Overcurrent fault.  After re-reading the datasheet again, it seems that the driver itself disables all outputs and doesn't really allow for braking to happen. Below is the reference of this statement:https://www.st.com/resource/en/datasheet/stspin32f0601.pdf page 18,"If the impulse on the CIN pin i

Hello!We are trying to run the BLDC Motor (BL34E34-01) in speed control.A project was previously shared with us that allowed us to run the same motor in position control mode. Given a target position and duration, the motor reaches the final position smoothly.However, when we used the same project, but changed from Position Control to Speed Control, the motor behavior is inconsistent. If we keep the same settings, or if we change to another BLDC motor settings (say BL17E19-02), the motor will rotates for 1-2 seconds and will come to a stop eventually. After coming to a stop, the current and power will still be high. By changing the encoder alignment from 0 to 90, there was no difference, but if we changed from 90 to 153, the duration of rotation increased by a couple of seconds, but it still comes to a stop later. The only situation where we have been able to rotate the motor, without coming to a halt is when we update the speed sensor mode (in the MC Workbench) from Qua

Hi,I'm using STM32G432RB Nucleo board with X-NUCLEO-IHM16M1, and connecting a 3-phase DCBL motor (RaceStart BR2205, which requests 7.4V - 14.8V).Followed with the instructions in UM2415. I used a power supply with 12V/2A on X-NUCLEO-IHM16M1.D1 EN/FAULT LED is always red, and D8/9/10, Motor Phase LEDs are never turned On, before or after I pressed the Blue Button (Start/Stop Motor) (on STM32G432RB Nucleo board).Here is how I generated the code:MC Workbench 6.3.0, FOC/3 ShuntSTM32CubeMX 6.10.0, STM32Cube FW_G4 V1.5.2MDK-ARM V5.32No error in each of these steps of the project and the code generation.When I pressed the Blue Button (Start Motor) (on STM32G432RB Nucleo board), I saw PC13 (Start/Stop pin) generated a pulse.Am I missing anything in the setup?   

Hi,I have been getting an error while using MC Workbench to drive ihm03 motor and motor driver package, i haven't satisfied by the answers in forum so i solved it in a different way.At first in installation phase (while setting up STM32CubeMX), i was chosing "Install for me only (recommended)" option for installation mode therefore MCSDK was not to be able to see it from its path. To solve my problem i decided to choose "Install for all users" option. Then now i can generate code in MCSDK. 

Good Day,I've run into some issues with the power supply scheme for my custom board using a STSPIN32G4.My design uses an external 5V switching regulator to power the internal 3.3V LDO, VM is switched on on-demand by signal from the MCU.My observation is, that VM needs to be present in order for the internal 3.3V LDO to function, is that correct? This is not clear at all from the datasheet, as it looks like the LDO is completely independent. Upon investigation, I found section 5.1.2 which vaguely hints that my assumption is correct.If that is indeed the case, this must be made more clear!Additionally, this section hints, that even if the LDO is bypassed and the 3.3V externally supplied, turning VM on causes a device reset. Is this some inbuilt safety feature? Can this be turned off?I’d be glad, if the datasheet could be a bit more precise about these topics. This is somewhat sad, because STM typically provides excellent datasheets.Cheers,D. Frejek

[This inquiry was made using a translator. Please understand.]hello.I would like to inquire about how to control a BLDC motor using the L6229Q motor driver.The operating environment is as follows.MCU: STM32G431KBUxMotorDriver: L62229QThe motor was controlled using the PWM of the MCU.The PWM signal is connected to the Vref pin of L6229Q.PWM frequency: 16.6kHzThe motor works well, but there are two problems.There is a change in motor speed from duty ratio 0% to 27%.However, there is no change in speed at a duty ratio of 27% or higher.It seems strange that the motor's limit is reached even with a small duty ratio.A high-frequency sound is heard when the motor's current consumption is approximately 240 mA or more.Even if you increase the PWM frequency, the sound is the same.The schematic of L6229Q is attached.If you know the cause, please help.  

Hi,I'm using 6 Step Motor Control and wonder what's the unit of the returned value from STC_GetDutyCycleRef() in speed_ctrl.c?I set the reference speed to 1000rpm. After I started running a motor, I saw the returned value from STC_GetDutyCycleRef(), ramping up to 3200 from 0.I would expect the returned value from STC_GetDutyCycleRef() to be 0 - 100 (%).What's the unit of the returned value from STC_GetDutyCycleRef() ? Thanks 

Hi ,I am getting the "Start up " failure after motor runs for 1sec or immediately  after motor start rotating.Could you please provide me the details of the all fault meaning and your suggestions to resolve this "start fault?if you need any further details, please let me know.Thanks and regards,Vijaysinha 

Hello,I am using the P-NUCLEO-IHM03 motor control kit together with a CubeMars GL40 KV70 motor with integrated AS5048A magnetic position encoder. I want to use the AS5048A  position encoder in my project, instead of the position estimator implemented by ST. To do that, I need to configure and implement SPI communication.My issue is that when I initiate SPI communication through the function HAL_SPI_TransmitReceive_IT, a driver protection fault is triggered and the motor won't start when I press the Start (blue) button. The following line of code triggers the fault:statusHalSpi = HAL_SPI_TransmitReceive_IT(&hspi1,spiTransmitBuffer,spiReceiveBuffer,3);When I remove this line of code, everything works fine, the motor will simply start up and run.The encoder uses SPI comm. in packages of 16 bits, thus I configured SPI in CubeMX with 16 bits datasize. Baud rate is 1.33 Mbits/s, CPOL is low, CPHA is 2 Edge. There is no issue with the SPI communication, I measured

I found MCM_POSITION_MODE typedef variable in mc_type.h code file but this variable not used anywhere in workspace.Can I control my motor position with my motor and Motorcontrol Workbench 6?I use now Nucleo-g431rb and X-Nucleo-IHM07M1 drive board with my custom bldc motor. Thank you.

A standalone installation of STM32CubeMX could solve the problem. But I'm worried that if the version of the two mismatches there may be some potential problems in future, since STM32CubeIDE auto-updates frequently and the included STM32CubeMX may update automatically. Is there any settings to make MCSDK using STM32CubeMX installed with STM32CubeIDE?

Currently using ST MOTOR WORKBENCH 5.4.8. 1. LOOK question1.jpg   About the numbers in the square area in the picture below- It appears to be a converted number rather than the flowing current value. I would like to know the exact meaning of this number.- For example, if you get 10000, you can actually interpret it as 4A. Like this 2. LOOK question2.jpgThis is the speed measurement part. We are currently using the sensorless (Observer + PLL) method.1) I am curious about the exact physical meaning of Observer's G1 and G2 in the black square.2) I would like to know what actual changes occur when the P/I value of the PLL in the red square changes.thanks.

This is a website issue, but there was no better category for posting this. The MCSDK download options don't include 5.Y.4. They only include 5.5.x options. This was true in both a Chrome and Edge browsers in Windows 10. https://www.st.com/en/embedded-software/x-cube-mcsdk.html

Hi I have added the required details in the MC workbench and clicked on "Generate the project" After that, the below window pops up.  in that under Firmware Package Version it is providing the three option to select 1. STM32 FW V1.11.52.STM32 FW V1.11.4 (Recommended , not installed)3. Latestfrom that I have selected the STM32 FWV1.11.5 option and clicked on the <Generate> button  , but it completing the project generation with error.I need you inputs on the below points1. why project is generating with error , how I can resolve this error2. the second option STM32 FW V1.11.4 , where I will get this and what is the process to added this in the project , so that it will detect in the dropdown list in MC workbench. In advance thankyou for your support.    

I have an STEVAL-SPIN3201 board and want to connect it to a motor with Hall encoder. According to the user manual, the Hall encoder power supply could be 5V from USB or 3.3V from VDD, setting by JP3 (defaults to USB 5V). In the schematic, Hall signals 1/2/3 are connected to PA0/PA1/PA2 pins via 1k resistors, respectively. They are also pulled up to VDD by 10k resistor, in case that the Hall outputs are not pulled up internally. There are also R59/R60/R61 footprints but not populated, which may be used to divide the hall output to proper voltage for MCU pins. I have no idea what the Hall output voltage would be, 3.3V, 5V, or something else, from my motor (no document). My question is, if the motor outputs 5V hall signals, will the MCU be damaged? What is the general advice for connecting this board to a new motor without detailed document? Start from 3.3V supply? install resistors on R59/R60/R61 before trying to drive the motor? I just wonder how you guys deal with it nor

Hi everyone,I'm currently working on a FOC motor control project using a custom board with the STSPIN32G4 and STDRIVE101. I am using a single shunt resistor for current sensing and Hall sensor for speed sensing. Here are the details of my setup:Shunt Resistor: 0.015 ohmsOperational Amplifier Gain: 10.1Current Control Reference: 0.5A using MC_ProgramTorqueRampMotor1_F(0.5, 100)After configuring everything, my motor is able to spin. However, I am facing issues with the current control. When I set the reference current to 0.5A, the Iq value I read from the Cube Monitor is very noisy and has small values. For my setup, a value of 1500 should correspond to 0.5A. However, when I use a current clamp meter, I observe an RMS current of 8A and a peak current of 22A (10mv/A). These small values cause the integral term to become very large; thus, I think this is why the current from the current meter goes so big.Additionally, I monitored the three-phase currents hCurrA, hCurrB, and hCurrC inside t

why do i getting this eror

 Is my settings true?

I have setted max current = 1 A and in RevUp table 0.6 A. In Waveforms below, I am getting current around 0.05. Is this in Amp? Only this much small current is driving the motor? I tried increasing/decreasing the speed but value is almost this.Also, Can I somehow just make x axis as time in (seconds) ?      

Hello,I need to calculate motor load (triac controlled 1-phase universal motor on drilling machine) on ADC input of STM32G030. This is output from Hall sensor TMCS1101A2BQDR and the main frequency is 50 Hz. Triac speed control makes the pulse current on input with offset of half of 3.3V. (picture attached)Can you recommend me how to calculate the load effectively?My idea is to use sample frequency of 2 kHz (40 samples per period) and put the results to an integer array with length of 200 samples. Better to have 2 arrays and when the array is filled with samples, switch to other array and find maximum value of the first array.Do you know if there is better calculation possible with STM32G030?Thank you

"In the FOC algorithm, does selecting Hall sensors as the main sensor decrease efficiency? If so, if I change the maximum applied speed setting, when it reaches that speed, can it continue driving with the secondary sensor? Are there torque differences in the initial rotation of the motor when Hall sensors are selected as the main sensor in the FOC algorithm compared to the Six Step?"

Hi,I am confused on how I can get this board: EVLDRIVE101-HPD, to work.For context, I am simply trying to get the EVLDRIVE101-HPD to run a compressor motor.From my understanding, I believe I need to generate the code/firmware through MCSDK workbench and then compile the code through an IDE (im using STM32CubeIDE) into the EVLDRIVE101-HPD board with the STM32G071KBT. However, both softwares do not have the board (EVLDRIVE101-HPD) as an option in the setup.I have the board's JSON file which I believe can be imported in the MCSDK workbench but need further instructions on how?Could I please have some general help with this? As well as clear instructions on how to get this board to work with my motor?Any help will be appreciated. thanks!
