STM32 Nucleo Packs - Motor Control FOC and 6-step solutions for three-phase, low-voltage and low-current motorsI am following the user manual guide for the P-Nucleo-IHM001 kit. I have installed the ST-link driver, but cannot open the utility link tool. I have downloaded it and gone through the set-up but when I click on the application in the folder, it has the error message 'The code execution cannot process because mfc140.dll was not found. Reinstalling the program may fix this problem'. Have deleted and reinstalled but still has the same problem.

HiI want to use STM32F746ZG and IHM08M1 to control BLDC and PMSM.I already remove recommended bridges and resistor, but I have some issue.1.    F746ZG can’t connect motor profiler.if I only use a USB, there will shows an error. if I use USB and ST-Link both, there also shows an error.        Other people also have same problem, and the problem isn’t solved.       https://community.st.com/s/question/0D53W00000WbUKXSA3/st-motor-profiler-with-nucleof746zg-ihm07m1-connection-error2.    The default PWM pin map isn’t correct.The default pin of CH2N is E10, CH3N is E12.And the pin should be PB0 and PB1.3.    MC WB Monitor can’t connect the serial port when F746ZG connect to IHM08M1.But when I remove IHM08M1, it connects successfully.When I only connect CN11 on F746ZG to CN7 on IHM08M1, it also connects successfully.However, I connect CN11 on F746ZG to CN7

Hello, I am experiencing startup errors (with my custom PCB based on EVSPIN32G4 and a 5-polepair outrunner motor (10 kW, 48V, max. 200A DC) . I am driving the motor without any load, just simple startup, power comes from a switching mode power supply with 15 A current limitation.)To find the cause of the error I was looking at the waveforms during startup for I_ALPHA , I_BETA, I_A and I_B: The I_B and I_BETA_MEAS waveforms are phaseshifted to each other, and at one point during startup there is a huge spike happening to both. I_A and I_ALPHA_MEAS are exactly the same values, so the waveforms are perfectly laying on top of each other (so you think there is only one waveform). Is this a bug in motor pilot or is it normal that those two are exactly the same?What might be the cause for the sudden spike? Shortly after this, the motor stops with startup failure. Here I have a graph of I_D, I_Q and ref values of both: and for more details I include the voltages as well:I also include the PLL

Hi, I am using STEVAL-SPIN32F04 dev kit to start my learning curve on STMC.

Hello Friends.May you help me?In Section 8.3 (hall sensor feedback processing) of STM32F SOC SDK manual. This section mentions to Hall electrical phase shift.So, could you tell me how to get the Hall electrical phase shift? what kind of equipment can I use to determine this parameter? such as oscilloscope or others?Thank you so much.

I am working with a DN4240S24 motor, to do some tests using the motor control SDK, but I am having trouble with the start-up. This is my first time dealing with motor control, so I apologize in advance if I don't grasp certain concepts right away.These are the motor parameters I have available. I am using a NUCLEO-F401RE + X-NUCLEO-IHM01. I decided to use the FOC algorithm and followed the highlighted steps. After completing each step and connecting everything, I tried to obtain the parameters of the motor model using the Motor Profiler.   The connection is successful, the motor starts running, however the Profiler fails to complete the operation. A message appears saying "The measurement is taking tootime.". Clicking on "Continue anyway", the operation continues but does not stop. Even trying to increase or decrease the speed the Profiler fails.So opening the Workbench I choose a generic Low Voltage motor and then I manually entered the parameters read he

Hi, I'm starting to design motor control driver using discrete analog H bridges - first time with STM32 micro. Currently using Nucleo G031K8 for experiments until custom board will be ready. So far I configured 3 PWM channels - normal and complementary central aligned PWMs (20 kHz) with deadtime using advanced TIM1 timer. TIM1 also generates update event trigger for ADC1 to start conversion. I'm using DMA to capture 10 ADC conversions in one sequence (2*3 values for H bridges and + 4 additional values). Using Cube and LL drivers. ADC settings captured in screenshot. It seems to work, TIM1 update interrupt comes in the middle of PWM pulse as expected. ADC data are coming into DMA double circular buffer, half transfer interrupt takes about 4.8us: 64 MHz internal oscillator clock, 32 MHz ADC clock, 1.5 clock sampling time. Based on datasheet formula it is: (1.5 + 12.5) * 1/32MHz * 10 = 4.4 us - close to expected value.Now the problem - I want to read motor current (the first ADC channel)

I'm able to run the demo program. But by starting a project from scratch will not moving the motor.

Opening the example ACIM-STM32G431 .ioc file in a text editor (notepad) shows hundreds of hidden options:I am trying to imitate it through CubeMX, but the parameter settings are not listed under MotorControl. I have matched all the other parameters. According to the GUI in CubeMX they are identical, but these hidden options are completely different.

I designed my own motor controller board and it works fine. For the next revision, I am looking into reducing parts count and simplifying schematics a bit. In the sense control area, I have tested the option of using the internal gain for the OpAmps and it works great. Digging into the code, I noticed that there are only two OpAmps being used. So is it possible to eliminate the third shunt? I noticed an input for the positive side from a third shunt (generated by the 5.Y.4. MC Workbench). That is the M1_CURR_SHUNT_W which is a signal on OPAMPV2_VINP_SEC and COMP4.Is it possible to eliminate it? I really wanted that pin if available for one of my Hall sensors input.

Hello community!I use a custom motorcontrol PCB with the STSPIN32G4, using the µc's internal OPs with external resistors to setup the gain. I use the same resistors as EVSPIN32G4 only with 0.5mOhm shunt instead of 5mOhm (see picture). With this configuration, I should be able to sense currents of up to 450 Amp. When no current is flowing through the shunt, the measured voltage on the OP out is 1,65V which is correct. The problem is that at 15A flowing through the shunt, the OP output is at 2V already. So the gain is far higher than what I enter in the workbench (gain in workbench is 7,333 and with the observed voltage output at 15A I calculate that the actual gain is around 48). There seems to be something wrong with the gain settings. In the changelog of SDK 5.Y.4, it says, that in version 5.Y.3 standalone mode for STM32G4 could not be processed by cubeMX: So I thought maybe this is fixed in the new version, but apparently there is still something wrong. The OPAMP settings are as

I keep investigating why I have problems driving my motor with negative speeds. I captured the phase voltage directly on the motor leads (yellow, cyan and magenta channels) and the current on the DAC output (Ia or Ib) and I noticed this peaks on the current waveform. Zooming in, the currents themselves don't look bad at all However I do not understand where does peaks are coming fromAny ideas will be greatly appreciated.

I would like to ask a question about "st motor control workbench".When I generate the sample project of STEVAL-SPIN3204, I get the following error.I want to solve this error.If anyone has been in the same situation and was able to solve it, please help me.

its mentioned in the code 3 elements maximum .but i need to control 4 lights and 2 pwm control for fan.

Hi, I'm new to the STMicroelectronics environment and I'm having issues with the EVSPIN32F0601S1 development board. I'm trying to spin a motor but I'm having issues connecting the evaluation board to the Motor Pilot GUI. I followed the video from the DevCon 2020 presentation video, but I'm getting a "Port open and try to configure the board" message from the Motor Pilot GUI. My work flow goes as follows:Use Motor Control Workbench 5.Y.4 to configure the settings for EVSPIN32F0601S1 board.Generate .ioc file.Use IAR embedded workbench to convert the .ioc file to code.Rebuild code in IAR embedded workbench.Download and debug code to evaluation board.Try to connect Motor Pilot to evaluation board. Here are some images, hopefully they help.

Hi, I am using CubeMX generates the application that contains MCSDK, The generated code has both stmg4xx_mc_it.c and stm32g4xx_it.c. I noticed that all the motor control related ISR code are coded in stm32g4xx_mc_it.c and I am confused with 2 issues:The generated ISR function prototype can not be found in startup_stm32g474xx.s. I am wondering how the ISR can be referenced in vector table.If I need to add more ISRs, where shall I put the ISR functions? Under stm32g4xx_it.c or stm32g4xx_mc_it.cYour kindly help is greatly appreciated.

In the workbench (5.Y.3 MCSDK-FUL) there are two locations to set/calculate the OP-gain. One is located under "Analog Input and Protection" and one under "Current Sensing". In my configuration I use external resistors so set the gain of the OPAMP. I found out that if you set the gain using the "calculate" button under "Analog Input and Protection" by entering all the right resistor values, and then go to the "Current Sensing" menu, the gain showing there is the same that you entered in the Analog input section. Now I save the project under a new name as Configuration 1 and generate the code. When I check the source code I can find the gain is set to as 7.333 (power_stage_parameters.h). Now back in the workbench I change the resistor values under "Current sensing" menu using the "calculate" button, I set the gain to 1 and click on "confirm". Now the gain value is changed only there under "current sensing", but if I go to "Analog Input and Protection", the previous set gain value is stil

After getting the example ACIM program running (Nucleo-G431RB and STEVAL-IHM023V3), I want to customize beyond those two boards. To do this, I believe I need to generate (or hand-make) a .ioc file.Trying to generate a file through MC WorkBench just creates MotorControl on "Enabled," while using STM32CubeMX doesn't show MotorControl under MiddleWare at all. What are some possible solutions?

Hello, I recently moved to the new 5.Y.4 version of the SDK because I am using a custom PCB based on STSPIN32G4 with external OPAMP resistor network (external gain) and after hours of searching I found out that 5.Y.3 doesnt support OPAMP in standalone mode due to a bug which has apparently been fixed in 5.Y.4, but now that I moved to the new version and do the workbench project new from scratch and building the code, I get the error "ST Intranet updater server unknown" (I get this even with standard settings) and in CubeIDE there are also errors when building the project which are not linked to any certain .c or .h file, the error occurs in the linker block as it appears.any help is greatly appreciated.

Unfortunately, I cannot get MCSDK to generate the Middleware with the Induction option, as it either does not appear (v. 6.0.0) or it fails to generate pwm_curr_fdbk.c properly (v. 5.Y.4). The other two algorithms generate fine and can run my setups. From what I've seen so far, Induction seems to be newer and is only supported in 5.Y.x.
