STM32 MCUs Motor control

We started using the L series of the ST Micro for a project and found that it does not have CORDIC functions. What is the best way forward? Do we need to implement on our own? Or we have to migrate to G4 series. 

Version:  MCSDK 5.4.8 / MCSDK 6.2.0Tool: Firmware / MC WBEvaluation Board: IHM042-V1Details:When using MCSDK 5.4.8 I am unable to have the first motor perform in the same manner as the 2nd motor despite all parameters being identical and the same motor / encoder being used on the other motor 1 output.  I am attempting to control both motors using single shunt current sense and incremental encoders that have 1024 pulses per mechanical revolution (They also have a "Z" index).SB1 has been replaced with a 0 Ohm jumperSB2 has been replaced with a 0 Ohm jumperR72 has been removedR76 has been removedJP1, JP2, JP3, and JP4 are all placed in the correct position for single shunt current senseExpected Behaviour: Both motors are controlled smoothly (as motor 2 does).I have just installed MCSDK 6.2.0 but cannot select single shunt current sense at all.  The only current reading topology I am allowed to use is Three Shunt Resistors.  I would like to determine if my issue with 5.

Hi,I have a Nucleo-F302R8 and a Steval-IPM10B, and I would like to configure speed control using UART communication. I have connected an external ARM Cortex-M4 to communicate with the Nucleo to control the speed. Could you please suggest a library or provide source files to help me configure this?Thanks in advance.

Hi there,I am having issues spinning a BLDC motor using the EVSPIN32F02Q1S1 development kit, and after searching through the data brief and cross referencing the schematics with the values populated in MC Workbench, I found a discrepancy in the current sense gain.In the image taken below of the Current Sensing tab from MC Workbench, the current sense gain is hardcoded to 3.33, and it cannot be changed. I am using MC Workbench version 6.1.2, and have imported the EVSPIN32F02Q1S1 board settings from MC Workbench.In this next image, taken from page 4 of the EVSPIN32F02Q1S1 databrief, if I am understanding correctly, the gain is simply the non-inverting op amp gain of 10k/3k+1 = 4.33, so it seems like MC workbench forgot to account for the +1.I tried manually going into the .ioc file and changing the gain to 4.33 but that didn't solve my issue, so I am still testing out other things to get the motor spinning, which I will likely make a separate post for if I am unsucces

I have an ST SPIN 3202 board and MC Workbench, Motor Pilot both versions 5.Y.3. I opened the example for ST SPIN3202 sensorless six step motor control in MC Workbench and then I generated it in KEIL microvision 5. I changed the parameters for my BLDC motor and it is all working correctly. The only thing missing for my project is to be able to change motor speed. The potentiometer on ST SPIN3202 does not change the speed neither the chainging in KEIL code. When I try to connect it with Motor Pilot I get an error: Board open and trying to configurate the board. I have the same baud rate and everything should work fine.I read on forum about this: when using STEVAL-SPIN3202: MCSDK-Y's Motor Pilot does not work with the SPIN3202 even though is shown as an option. You need to use MCSDK 5.4.8 and its Motor Monitor utility.So can you tell me how do I connect to Motor Pilot so I can see all the parameters and change the speed easily. (I can not found the version MCSDK 5.4.8 to download). Or whe

Hello.I am testing using MCSDK 6.2.0 on EVSPIN32G4 board.I've checked the operation of the motor using the start/stop button.The problem takes approximately 3 seconds or more to stop during operation at a maximum speed of 16000 rpm.I want to stop urgently, what are the ways?Regards

I have generated the code with workbench 6.1.2 planning to migrate to 6.2.0 but meanwhile i am finding one issue consistently. I am using digital hall sensors and i am constantly getting a gap as below in the rotor angle after every some duration. Is it normal this is the cube monitor logging?I have captured the phase current and i find a small glitch which happens consistently.If it is related to the rotor position. Please help to solve this issue.

Looking for a motor control board for test and evaluation of low voltage hub motors 48-80Vdc and 50-100A or at least something in tens of Amperes range; I have found that Matlab/Simulink suggests a combination of Nucleo-G474re Board X-NUCLEO-IHM07M1: Driver expansion board for their example model https://it.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/stm32-parameter-estimation.html that could be a good starting point for a much smaller motor, to get parameters and to get familiar with the use of the software model together with the hardware; could someone point me toward a bigger motor control board, adequate for my motors but with the same interface toward the Nucleo board (with or without adapters like the IMH09 ) so that we can easily upscale the test bench without restarting from scratch both software and hardware? Thanks.

Hello everyoneI'm trying to control a motor using STC_SPEED_MODE. There's a problem at startup: I program a ramp (for example i would like to obtain 6000RPM), motor start to rotate and accelerate, but speed reach maximum speed for the motor (for example 9000RPM) then decrease slowly to desired speed.Once speed is reached, if I try to change speed with a new ramp from 6000 to 7500 RPM, it works quite well (system is not fast to change, but much better than at startup).I thought it could be for PID parameters that are no so fine tuned, so I tried to play with this values, but at the startup I've not otained any changes.Here the code at startup, where hDesiredMechSpeed is 6000 :MC_StopSpeedRampMotor1(); MC_ProgramSpeedRampMotor1((int16_t)((hDesiredMechSpeed)/6), 1000);MC_StartMotor1();When motor is in RUN state a speed variation request is covered by the next snippet, where hDesiredMechSpeed is the new desired value:if (bDesideredSpeedChanged){ bDesideredSpeedChanged = FALSE; MC_Sto

I often use Motor Profiler to identify motors.But it is not good.Sometimes my motor cannot be recognized when using 48V and I have to reduce the supply voltage to 36V.Here I would like to ask whether it will be open sourced. I want to understand the principle of identifying the motor and improve it.

Hello, I recently purchased EVSPIN32F02Q1S1 and attempted to flash it with the FOC firmware generated through MotorControl Workbench 6.1.2. However, I was unable to upload the code onto the board and instead greeted with the following message in CubeIDE:The message was seen when I hit the debug button.I triple-checked the HAL and code generations from MC and CubeMX to ensure the code being debugged had no problem. I believe this is likely to be a hardware issue since I was able to flash other EVSPIN32F02Q1S1 with the same computer. Then I noticed that when I plug in the "faulty" EVSPIN32F02Q1S1, I see this fail text file:I don't recall changing any hardware configurations for the board and I am running out of things to check for.  What could be the problem? 

I am using STM32CubeIDE 1.12.1 and MC Workbench 6.20 to generate the profiler firmware to run with the Motor Profiler software. I am running into two problems.The first one: If I use the P-NUCLEO_IHM003 kit in the Example Projects to generate the code, I don't have this problem. If I create a new project by selecting the motor and the power board (same as the example) to generate the code, I get this error with the static function "R3_1_RLGetPhaseCurrents()".In file included from ../../Inc/mc_config.h:40,from ../../Inc/motorcontrol.h:25,from C:/Users/dc2ac/.st_workbench/projects/motor-profiler/Src/mc_interface.c:28:../../MCSDK_v6.2.0-Full/MotorControl/MCSDK/MCLib/G4xx/Inc/r3_1_g4xx_pwm_curr_fdbk.h:263:13: warning: 'R3_1_RLGetPhaseCurrents' declared 'static' but never defined [-Wunused-function]263 | static void R3_1_RLGetPhaseCurrents(PWMC_Handle_t *pHdl, ab_t *pStator_Currents);| ^~~~~~~~~~~~~~~~~~~~~~~The second problem is when I included the motor profiler checkbox in the appli

MCSDK 5.4.8 profiler work and MCWB work, code generated.Motor is able to spin under MCWB, but even HALL option is selected, MCWB is spin without HALL and therefore its generated code is not aiming for HALL startup right? I tried many different combination of below parameters, I can make small motor spin by adjust and focus below parameters, however when I try my skateboard motor (little bigger) I have no luck to make it work, I already spent 4 weeks to understand the speed_torq_ctrl.c and adjust parameters without any luck.Can anyone help to tech me more on PID parameters ?PID_SPEED_KP_DEFAULTPID_SPEED_KI_DEFAULTPID_SPEED_KD_DEFAULT  SP_KPDIV_LOGSP_KIDIV_LOG  SP_KDDIV_LOGIQMAXmany thanks in advance,Danny

Hello Community,I am sure about everyone being aware of the classic initial encoder alignment error in FOC. I am trying to bypass the entire alignment procedure by a method using calculated angle from Hall Sensors. I plan to run the motor initially in Six Step algorithm for few seconds to get sufficient hall edges , then calculate the electrical angle from hall sectors for the FOC switchover. Has anyone tried such an approach yet? Is it practically possible?I hope someone can help me in this.Thanks,Best Regards

HiI am looking for hints - how to implement the encoder from which I read the position via SPI?Should I set the encoder with index in Motor Control Workbench? If so, where to write the position read after SPI to "pretend" an ordinary encoder? I also see that the encoder index (Z) raises an exception - this is where the motor speed is taken? Generally I want to use the motor in position mode with torque control.Have any of you already run the SPI encoder with MCW?

Does ST have a tentative roadmap for supporting the STM32H5 series in the X-Cube-MCSDK?

Hi all.I use Nucleo-F746ZG, X-Nucleo-IHM07M1 and Maxon motor (https://www.maxongroup.com/maxon/view/product/motor/ecmotor/ecflat/ecflat45/668555). These boards were purchased separately.Motor Profiler and Motor Pilot give a connection error. CubeIDE connects and flashes the board without problems.After two days of attempts, I realized that I can connect only in STLINK mode (it does not connect via UART).Another day later, I generated the firmware using MotorControl Workbench and installed it using CubeIDE. In the firmware, the port speed was set to 115200.Now the Motor Pilot was able to connect via UART, but he still cannot control the motor.The manual say that before testing the motor, the Motor Profiler installs the firmware necessary for its operation on the board, but it seems to me that this is not so.Now I lean towards the fact that I need a basic firmware for STM32 to test the motor.I would be very grateful for any idea or information!!!Thanks in advance!

When I want to generate a project, this error stops me.Is there any installation steps that I skiped?

Hello, I'm Used To Use MobaTools Library To Run Stepper Motors In My Projects With Arduino Nano. But Now I'm Working On A Project With STM32 Board And Just Found Out That MobaTools Doesn't Support In STM32. So, I Wanted To Know If Anyone Know Alternative Of MobaTools Library To Control Stepper Motors ? Thanks For Your Considerations Even If You're Just Going To Read And Skip And Any Help Is Much Appreciated.   

Hi,   I have been using STM-STUDIO-STM32 for moitoring the real time variable while motor running without disturbing the program.  MCU used - Stm32F103c8t6 Debugger used - st-link v2 Software used - Stm-stdio  - The stm-stdio is get stopped while debugging and ended up with  showing the following error code: ''Acquisition stopped after 10 consecutive communications error'' @while motor is on loaded condition. - @Motor no loaded condition stm-studio seems fine. - Does any other software or debugging tool (for stm32) is available to monitor the real time variable for motor control.
