STM32 MCUs Motor control

[Basic Info]We're currently having issues with our custom board.It is based on the G431RB in FOC and 3-Shunt mode, with a DRV8323RS as the gate drive and for amplifying and attenuating the current measurement.The motor is a low-inductance (8.1µH) high-power BLDC motor with integrated Hall-sensors.The System is set up as an inverter in 3-Shunt mode, with all three current measurements using one ADC (hardware requirement).MCSDK Version used is 6.2.1, with STM32 FW for the G4 being V1.5.1 (as recommended) in HAL mode.Following tests were performed to verify the proper function of the hardware:- Check of the hardware for shorts and proper voltages- Check of the gate drive signals for correct switching, including dead times (generated by the gate driver)- Check of the current measurement paths, including amplification and conversions inside the library (the current values output by the Motor Pilot properly represent the voltages measured at the shunts)- Check if the actual motor parameters

I want to generate a code for STM32F767ZI but this MCU is not supported in the STM Motor Control workbench V5.4.8.Available STM32F7 family MCUs in Workbench are STM32F746 and STM32F769. I have generated code for the STM32F746 and flashed that code into STM32F767ZI but it is not working.From some online help, it was found that both MCUs are the same and one can flash the code interchangeably into controllers. Questions:1- Is this possible to flash the code of STM32F746 into STM32F767ZI? If yes, why my code is not working even though I flashed the code into STM32F767ZI, still, I am still unable to build a communication between the Monitor window of Workbench. The COM port is not detecting. 2- if not possible, then should I have to buy a supported microcontroller?Thanks and RegardsNoman

For our motor control project we're using a driver IC with integrated opamp stage intended for current measurement.This opamp stage inverts the current reading compared to the Current sensing signals conditioning model, see here:To correct the current reading, could I simply put a negative gain value?According to an article about an older version of the MCSDK, that didn't work. Would that be possible with the MCSDK Version 6.2.1?

Hi!Trying to use a Leopard LC2830-980KV motor with the B-G431B-ESC1. I have managed to program the device with the MC Workbench and can run the motor using the Motor Pilot software. However I can't seem to get the speed over 2100 rpm for some reason. I can get the motor to speed up to 2100 pretty rapidly when playing with the rev-up settings, but when I request a faster speed it just stays at 2100 rpm and starts to draw more current until eventually my power supply (5A) goes into over current. Any tips on what I can check/test? Thanks,Carl 

HI, I am currently doing a project with the B-G431B-ESC1. I am trying to control a motor with the B-G431B-ESC1. I already have profil my motor with the motor profiler software. I am able to control my motor with the motor pilot software. Now, I am trying to control my motor with an external PWM input. I send a PWM signal at 490Hz with duty cycle value between 1060us and 1860us with a ESP32 (the signal is corect, i have verify with an oscilloscope). The B-G431B-ESC1 detect the PWM and beeping when i switch off the signal. However, I am not able to control the motor with the PWM. My motor start running at constant speed doesn't matter the duty cycle value. Thanks.

I added a custom REG in Motor Pilot and edited the MC_FOC_SDK.qml file, which allows usage, but I can only input integers, not floating-point data. Here is the configuration information. RegListSTMV2.json {    "Id" : 162,    "Name" : "OVER_BUS_CURRENT",    "Description" : "max bus current",    "Type" : "F32",    "Unit" : "A",    "Scope": "Motor",    "Access" : "RW",    "UpdateFrequency": "MediumFreq"}MC_FOC_SDK.qmlMcRegGroupSpinBox {    RegDesc {            regName: "OVER_BUS_CURRENT"            decimals:1            label: "max ibus"           from: 0           to: 500          stepSize: 1         tooltip:"（0-500)"    }}

HelloI'm trying to run a refrigerator compressor (basically a PMSM) with EVSPIN32F06Q2S1. I downloaded all necessary programs and started the MC Workbench, configured the board in sensorless FOC and uploaded the code to it. All that works fine. But when i try to run the PMSM via Motor Pilot, i instantly get "Over-Current"-Fault. When I turn off the Over-Current-Protection, I get "Speed-Feedback"-Error or "Startup Failure"-Error. I tryed to solve the Problems with the Tips from FAQ on the Official Website, but none of them seems to solve the issues.Motor-Parameters I entered in the MC Workbench should be fine, I'm just not sure about Inertia and Friction. Maybe someone can suggest me realistic parameters for a refrigerator compressor? ( I dont have a datasheet, the electrical parameters i measured by myself...)Thank you very much for helping me, I pretty lost right now :)Greetings I also added two screenshots which show my view on MC Workbench, Motor Pilot and Sensorless Start

Using the motor control program generated by Workbench_6.3.0, Motor Pilot_6 can communicate normally. However, when sending manually using a serial port assistant, it always replies with 0F 04 04 C0 and cannot communicate normally. This issue does not occur with the motor control program generated by Workbench_6.2.1.[16:15:36.452]TX→◇85 FF FF BF [16:15:36.460]RX←◆05 C3 00 D4[16:15:41.357]TX→◇05 C3 00 D4 [16:15:41.369]RX←◆05 C3 00 D4[16:15:48.537]TX→◇06 00 00 60 [16:15:48.543]RX←◆F6 00 00 C0[16:15:59.895]TX→◇49 00 00 70 10 00 28 00 [16:16:01.375]TX→◇49 00 00 70 10 00 28 00 [16:16:01.380]RX←◆0F 04 04 C0 0F 04 04 C0

We're currently having issues with our inverter.To further analyze the issue, I'd like to test the proper function of the motor phase current measurement.How should I go about doing that? Since the motor currents are measured in injected mode syncronized to the timer, I cannot just insert a static current into the shunts and look at some registers.Is there a way to enable a "test mode"? Could I use the high speed plot for that?I already tried running the motor and graph the input of the motor current ADCs with an oscilloscope to compare it with some of the plotted graphs, but I could not find any that matched.

The Motor Pilot 6.0.0 application is not starting. I have testet it on Windows 10 on a real machine and on a Windows 10 virtual machine. When I start the application the course briefly shows that the machine is working but then nothing happens. No error messages.Has anyone experienced similar issues?

Hello,I am trying to evaluate the use of MCSDK in a dual-motor application.  Motor 1 works, but motor 2 does not.I have a fresh Workbench project, with both motors configured identically, with the exception of Over-Current Protection.  When I generate, I get a "NOTICE: Please disable the overcurrent protection of Stage 2 to avoid resource assignment conflict on COMP2.  The power state is already protected by STDRIVE101."  Under Current Sensing of Stage 2, I disabled Over-Current Protection, but still get the notice.The generated CubeIDE project compiles and uploads without issue.I use MC_FOC_SDK_2_Motors to try to start/stop the motors.  After connecting, I hit press Start on Motor 1.  I hear the PWM, and after a second (as expected), the motor starts ramping according to my startup sequence.  When I press Start on Motor2, I get no sound, and no motion.I analyze the outputs to the motor with a dual channel oscilloscope.  On Motor 1, U, V, W signa

We have been told Asymmetric Serial Packet Exchange Protocol documentation would be available with the release of MC Workbench V6. We're at V6.3 now. Can you direct me to where I might find said documentation?The old serial communication class available in MC Workbench 5.4.8 doesn't seem to work with the new Workbench versions.Here I sit at 5.4.8 wondering, where is the flying car I was promised?Thank you in advance.

I want to use a STSPIN32F0B to control a brushed DC 24V Motor with encoder.Can everybody give me a example or suggestion how to do that?

Hi everyoneAre there any experiences with Motor Controll SDK 6.2.1 with NUCLEO-H745TI-Q and extension Board X-NUCLEO-IHM07M1?I try to get a basic FOC - Speed controller running on my NUCLEO-H745ZI-Q. But I struggle  completely.Something goes wrong. Nothing is running by default. I can generate the project in the Motion Workbench without error.But after, if open it in the ST IDE. I have a lot of warnings in the CubeMX Configuration. Not sure is this normal.If I try to debbg it, I got an out of scope error from the debugger after a short time. ("0xa05f0000" with no debug information available, or outside of program code.)This is a two Core CPU and the code is running on CM4. This happens even i start the CM7 in the debugger before the CM4. I can do a little debugging if I desable these two lines:// __SEV ();// __WFE ();(Section see below...)  If I do so, the debugger hangs in the ACD calibration state and goes not further... It seems that something is wrong

can i use these pins for my motor PWM inverter 

Hello All,I just Bought an Evespin32G4 dual Board.https://www.st.com/en/evaluation-tools/evspin32g4-dual.html I completed the configuration using the X-CUBE-MCSDK-6.Goal: I will command 2 motors 36V, 4A (Moteur Hoverboard)I generated the cube ide project. When I run mc_startMotor1 (), the motor 1 starts training, then I tested the second motor mc_startMotor2 () and is turning.Then I tried to run the 2 function one after the other to turn the 2 motor at the same time, for some reason just one of them turn, when I reset it seems like sometimes the first motor turn, and other times the second motor turn.So please any idea, it can be something in the configuration.

Hello community members,I'm currently in the final stages of preparing a prototype, and I've encountered a problem with motor synchronization.Here's the setup: I'm utilizing the EVspinG4-Dual Board to control two brushless motors (hoverMotors), which have been profiled using X-NUCLEO-IHM08M1. After profiling, I developed a project using MotorControl Workbench 6.2.1.The issue I'm facing is that upon testing, I noticed a discrepancy in the response times of the motors. Motor 1, connected to the STSPIN32G431, is experiencing a delay in reaching the target speed, while motor 2, connected to the STDRIVE101, achieves the target speed immediately. Despite configuring both motors with a ramp speed and a delay of 0, motor 1 consistently ramps slower compared to motor 2.I appreciate any insights or assistance you can provide in resolving this synchronization issue. Thank you for your attention to this matter, and I look forward to any suggestions you may have.

I'm using a B-G431-ESC1 brand new board to profile a motor.When I try to detect motor pair pole the procedure stop with Over Current  error.This hapen even the motor is not connect.The 6 mosfet are tested and they are not in short circuit.How is possible  that even without motor there is a Over Current error ?
