STM32 MCUs Motor control

After rigorously following the instructions numerous times with every possible STM32CubeMX, Toolchain, and Firmware configurations, the build always fails to generate ...\Src\pwm_curr_fdbk.c. The error is that MC.SINGLE_SHUNT is "evaluated to null or missing."I have tried uninstalling and reinstalling, trying to compile anyway, editing the .web_df file, changing settings in the Workbench, and more. 

STEVEL_STSPIN3201 even st link beside led also not glowing i dont understand what to do plz suggest me the process

I'm able to develop the project for a general brushles motor but I'm not able to convert it into an ACIM controller (using ACIM_GUI and/or the ACIM library).

Help! I'm new to ST development tools. All I'm trying to do right now is generate an MC Workbench example project. Any example project.MC Workbench GENERATION always reports the following error:"The ST intranet updater server is unknown: mcucrossselector.codex.cro.st.com"Any suggestions greatly appreciated.-----Details:MotorControl Workbench 5.Y.4 (en.X-CUBE-MCSDK_5.Y.4_v5.5.4.zip)STM32CubeMX 6.4.0 (en.stm32cubemx-win_v6.4.0.zip)STM32CubeIDE 1.7.0 (st-stm32cubeide_1.7.0_10852_20210715_0634_x86_64.exe)(All downloaded and installed yesterday.)It does generate a CubeMX project, which generates a CubeIDE project, but that source code is has a massive number of undefined symbols. I have not changed any config or preferences settings. It's all "fresh out of the box", and I'm just following the provided instructions.((Context: I have 2 new B-G431B-ESC1 boards, and started out trying to build the example projects for that board. When that failed, I started trying other examples, and it looks l

Hi, I use the timer3 to detect PWM Duty cycle from the input signal. The signal is an angle sensor from a BLDC Motor. That means 0% DCy is 0 grad and 100% is 2pi grad. The sensor has 4096 bit resolution. But I have a problem to detect an overflow interrupt, because in PWM Mode, Rising Edge and Falling Edge Interrupts are also active and seems that all three interrupts call the function HAL_TIM_PeriodElapsedCallback after an event update. The problem in my application is, that in transition from 2pi to 0 grad, the PWM goes from 100% DCy to 0%DCy, that means for a whole period I don't have a Rising edge signal to detect the new period. I thought that with an overflow interrupt I can reveal that the period is over and if a rising edge does not occur then I am on the transition. Do u have any ideas?

I want to use Nucleo-G431RB and X-Nucleo-IHM08M1 3Sh to control a outer rotor BLDC with FOC. Now I am confusing how to set jumpers.In the introduction of Motor Profile:However, in the Quick Start Guide and User Manual of X-Nucleo-IHM08M1 3Sh ,the requirements are like this:On the X-NUCLEO-IHM08M1 expansion board, set jumpers: J9 open,JP3 closed. For 6-step control (X-CUBE-SPN8 FW), set jumpers: JP1 and JP2 open, J5&J6on the 1-Sh side. Keep capacitor C5 mounted; in case of poor motor currentregulation during startup, reduce its value. For FOC control (STSW-STM32100 FW), set jumpers: JP1 and JP2 closed,J5&J6 on the 3-Sh side. Remove capacitors C3, C5 and C7.Which one should I follow?Thank you very much!

The error is for the UART communication between the STM32F303 control board and the ST Motor Pilot software, but what does it mean exactly ? Where can I find information about such errors ? My best guess is that there is a problem with a buffer for the UART, but is the problem due to my PC ? Is the baud rate to high ? Is it due to using the high frequency plot feature in the Motor Pilot software ?

My ramp cranks current up to my max within 5 pwm cycles. I'm traced it down to STC_CalcTorqueReference, it calculates some increment value. I assume that's the issue. the math works out but something is wrong here. This is a custom power stage and I have gone over every part of the config, i've tested the current sensors and confirmed they match the configuration calculations. Would appreciate any suggestions where to look next. I understand the shunt / gain is weird, and they will be changed in the next rev but the value does come back correct (if a bit noisy) #define THREE_SHUNT #define RSHUNT 0.003 #define AMPLIFICATION_GAIN 200.0/***************** MOTOR ELECTRICAL PARAMETERS ******************************/ #define POLE_PAIR_NUM 7 /* Number of motor pole pairs */ #define RS 0.63 /* Stator resistance , ohm*/ #define LS 0.000042 /* Stator inductance, H For I-PMSM it is equal to Lq */ #define NOMINAL_CURRENT 8579 #define MOTOR_MAX_SPEED_RPM 15000 /*!< Maximum rated speed */ #define

Hello,In Motor Pilot, I can run my motor at e.g. 100 rpm, my speed PID is tuned with a non-null integral term.If I block the motor by hand, I can feel and see the torque reference increases to counter my blocking. Ok. But the torque reference never goes above 13887 s16A, and so the torque never increases enough to fully counter my blocking and move the motor again. The current drawn by my supply is then around 1.5A.My motor is a 24V BLDC motor, 13.5A nominal current, with a 1024 PPR encoder as main sensor, I set the value 13.5A as nominal current in Motor Control Workbench GUI (5.Y.4). I use a IHM08M1 3-Sh control board with a Nucleo F401RE.What is saturating the torque reference and how to rise this limit ?

The CANopen protocol can be added in STM32Cubemx6.5.0, which is great! I added the emotas. I-cube-canopen.1.1.2 extension package to CubeMX Software Packs. After the Build was set up, the code was compiled normally and started to run. However, after running for a period of time, a message indicating hardware failure is displayed.CANopen is said by Emotas to have copyright restrictions, is that the reason? Hope to guide the solution.

I have purchased the STEVAL-SPIN3201 board, but the STM32Programmer does not detect the ST-Link, the LEDs are not getting ON. I also purchased the external ST-LINK V2, with that i tried connecting and erased the memory. The USB driver also having problems. Please support to close the issues and program using internal STLink of the evaluation board.

If I measure the DC supply voltage for my X-NUCLEO-IHM08M driver board - connected to a Teknic motor (i.e. Hudson brushless servomotor), running the ST FOC SDK with speed control, we see that there seems to be some "charge-discharge" low-frequency square-wave on top of the DC voltage. Please see the plot. The DC voltage is 30 V. The speed reference is zero. The segment "Start motor" is an interval where the motor is in RUN state. Otherwise it is in IDLE state.What causes this "disturbance" ? Is this unusual ?

The code in mc_tasks.c in routine void TSK_MediumFrequencyTaskM1(void) callsbool IsSpeedReliable = STO_PLL_CalcAvrgMecSpeedUnit (&STO_PLL_M1, &wAux);This function computes the average mechanical velocity, among other things. The above function is not in the distributed source code, but is in the compiled object library. The source code is available in the final release of ST code MC_SDK_5.Y.4, but converting to this release from 5.4.4 would be a very large task. In speed_torque_cntrl.c in routine int16_t STC_CalcTorqueReference( SpeednTorqCtrl_Handle_t * pHandle) the function SPD_GetAvrgMecSpeedUnit(pHandle->SPD ) is called to get the average velocity. This routine accesses the velocity from a structure updated from the first function above. This routine is apparently overflowing as indicated by logging the return data shown below. The ST code in this function uses a variable int32 wAux that overflows. The beginning values fits int32 and the final value fits int16 but a

I can't profile motor using inverter EVSTSPIN32G4 and MC SDK 5.Y.3?

i am referring document "STEVAL-ISA147V3" for our power supply project but could not findinformation about source code.it would be helpful, if i get a source code for the development or any link about it

After writing the code from the STM32Cube IDE to the evaluation board, the motor spins for less than a second and then stalls.Why does the code generated according to MCSDK_5.Y.4 not work?

The Quick Start Guide for this board implies it is compatible only with the following Nucleo boards:NUCLEO-F030R8NUCLEO-F103RBNUCLEO-F302R8NUCLEO-F401REDoes anyone know if it will work with any of the Nucleo F7 or H7 boards?

Where can i get the firmware of steval-spin3204?? that is, stsw-spin3204.zip.I have the steval-spin3204 board for testing a motor.I try to automatically generate the firmware with X-CUBE-MCSDK-Y tool.Unfornately, I got the error of "freemarker template error" on mc_tasks.cAnd, I suffered from this error of "freemarker template error" I did not solve this error.stsw-spin3204.zip is more easy for me.Thanks in advance.AShin.

Hello,I have STEVAL-SPIN3204 board and a BLDC motor with hall sensor.So, I try to generate a firmware with 6-step control and hall sensors.ST Motor Control workbench (v5.y.4) generate the firmware.But, the source code folder have not MCLib6Step folder that is the control library for 6step control.Also, mc_tasks.c.h in src/inc folders do not use the 6-step control library inside MCLib6Step folder, but do the FOC control library inside MCLib folder.How can I generate the firmware with 6 step control library.Thanks.AShin.

Hi CommunityI'm using the following setup:MC Motor Control Workbench v6.0.0STM32 FW V1.5.0 (HAL)Power + Control Board: B-G431B-ESC1Observer + PLL (Sensorless)Motor 10 pole pairMech. Speed 200rpmThe motor starts and ramps up to 200rpm.It can now happen that when there is a load change, the rotor suddenly turns at full speed in the opposite direction. The speed is displayed in the Motor Pilot. In this case, however, the phase current looks distorted.What can be the cause?

Hi,Will it possible to run ACIM ( V/F Open/Closed Loop or FOC ) with EVSPIN32F0601S3 and Motor Control Workbench 5.Y.2  or future versions ??--Karan

What is the difference between software versions X-CUBE-MCSDK and X-CUBE-MCSDK-Y ?Does the 'Y' implicate a final release in the current version ?

Cedric H, et al,I'm starting a new project (BLDC motor, 200-400w, battery powered, irregular speeds and loads -- think "power tools" profile) and would definitely like to use MC_SDK v6.x vs. earlier releases. Have worked with your earlier STM32 Nucleo pack (NUCLEO-F302R8, X-NUCLEO-IHM07M1, etc.), Anticipated using NUCLEO-G431B and X-NUCLEO-IHM08M1 for this project. But, alas, neither of these boards (or others supported by MC_SDK 6) seem to be available.Can you predict when single quantities of these development boards will be available? (DigiKey is out of stock and unable to provide an estimate.)Possibly not, since I suspect this is due to larger forces (e.g., the global chip shortage). But are there workarounds?I notice that the X-NUCLEO-IHM07M1 Power Board is supported by MC_SDK 6. I could proceed with the one I have and port to the higher power ...-IHM08M1 later. Would this port be simple or not?What Control Board could I use in the interim without having to regress to an earlier v
