STM32 MCUs Motor control

Hi, I got a Steval-ctm010v1 board and using sdk 5.4.8. I have tried to enable its PFC section with eliminating the warning from xml file at the sdk file location. It enabled the PFC in the motor workbench and it shows that pins are assigned at the motor workbench. But After generating the code, the pins aren’t assigned in Stm32cube MX so the PFC isn’t enabled in practice and it just generates the PFC codes (pfc.c and etc…) to be used in the main code. How can I enable PFC the right way? any Help would be appreciated.

 i m using customized stspin32g4ACT board , nd version of work bench m using is 6.3.1 but when i try to generate code there is motor profiler option is disable  although m using stm32ide 1.17.0 when i upload code for led blink using pc14 it turn but don't blink but when m upload code through Arduino it blink very good pc14 and pc13 both in st32ide it does not blink show suggest me where i lacking motor m using is 2 pole hall sensor code is blow  , i m new to workbench so pls guys guide me nd this is disable motor profiler image  

Hi,It is not an issue with ST software but wanted to clarify, my application requires different modes with speed limitation in each mode, to do that i have started controlling the CircleLimitationM1.MaxModule parameter in torque control mode which is the modulation index. Is it ok? since as of now i only used to control the Iq parameter but speed i could not regulate with Iq. I was successful in controlling the RPM but i want confirmation that it is ok to alter the maxmodule parameter as per the requirement, i am changing this in run time.  

Hello,I am using the EVLSERVO1 board and trying to monitor the DAC outputs with an oscilloscope, since the high-frequency plots in Motor Pilot are difficult to use effectively. I enabled DAC Debug in the FOC Wizard, assigning DAC Out 1 to PA4 and DAC Out 2 to PA5. After doing this, I checked CubeMX and confirmed that these pins are configured correctly.According to the EVLSERVO1 schematic, it looks like I should be able to connect the oscilloscope probes to pins 8 and 5 on the J2 connector. However, when I select a variable to output to the DACs from within Motor Pilot, I see no signal on the scope, just noise.Is there anything else I need to configure to get the DAC output working?Thanks

Hello everyone!Based on the shot I provided, there are some parameters that I don't know exactly how they are calculated.What are the Polarization Offset and Offset network attenuation parameters and how could I calculate them? Is there any user guide for that?It's very useful when designing a custom boardThank you all

I have implemented the following logic if the throttle signal is below a threshold i give Stopmotor command, it will take some time for the motor to come to zero speed, but the requirement is if i give throttle again the motor shall continue running but the problem is if i give start motor command i can hear a noise or jerk. I tried giving the command MC_ProgramTorqueRampMotor1(0,0) instead of the stop motor command, but power is still going to the phases and i can hear the sound and this is not acceptable to customer.  Please suggest how do i solve this problem.It is hall sensor based custom board.

Hi All,I have an STM32f302R8 with IHM07M1 with a Bull Runner 2804 motor. This may seem like a simple question but I cannot find any information as to reversing the direction of the motor. In my final project I will need to reverse the direction of the motor on occasion. Does anyone have any information that may help me?DonCorr

Hello,I want to use MCU pin A6 for something else and OPAMP2 to ADC2-IN3 shall be internally connected only.G4 Reference manual page 779 figure 171 says:opamp_out can be redirected internally to an ADC channel by setting OPAINTOEN bit.In this case, the I/O on which is mapped the OPAMPx_VOUT is free and can be used for another purpose. In standalone mode, VOUT pin is disconnected from the OPAMP output and the gain cannot be set by an external resistors (in this case OPAMP can be used only as comparator).When I look at MCSDK generated code

Hello,I am generating firmware using MCSDK 6.4.0 and testing my motor with Motor Pilot. I am using FOC with encoder feedback.Under no-load conditions, the velocity control loop works perfectly with the default PI gains, the motor tracks speed very accurately. However, the motor produces no holding torque and can be stalled easily with just my fingers at all speeds.I assumed this was due to a poorly tuned current loop, so I began increasing the proportional gain of the torque (Iq) PI controller in Motor Pilot while running in torque mode. During testing, I monitored the I_Q_MEAS and I_Q_REF registers while gradually increasing the torque current.There is quite a bit of noise in the I_Q_MEAS signal, but it is still clear that it never steps anywhere near I_Q_REF. Increasing the torque gain has no noticeable effect, the motor still pulls only a small amount of current, and the holding torque remains nonexistent.I have been searching for any hidden curr

I'm using the BLDC motor dev kit (F302R8 + IHM07M1 + BR2804 motor).  When I run the Motor Pilot with the SimpleAppMCPV2 to tell the motor to go to a commanded speed, I keep getting a speed feedback fault.  Similar thing happens with the MC_FOC UI.  The motor starts turning, and runs up to 0.6 amps, then the fault happens and the motor stops turning.  I see the feedback speed is in the thousands of RPM instead of the 150RPM I commanded. I've read that the speed feedback fault might be due to needing to lower the cutoff frequency, so I lowered it from 6000 to 2000 rad/s.  But I still get the speed feedback fault.I'm not sure if there's something wrong with my current feedback config or speed feedback config?  This dev kit should be running in sensorless mode (no hall sensors for speed feedback), with FOC.

I'm using the Nucleo-F302R8 and the X-Nucleo-IHM07M1 with the small kit motor it comes with.  I'm having trouble getting the motor profiler to connect to the board.The F302R8 seems to have the demo motion program running, since I can hit the blue button to start the motor turning.  But if I want to run the profiler windows application and try to connect to the board, I get this error:"Port Open and try to configure the board"I've tried updating STLink, and it's on the latest (v2.j37.m26).  I've updated my USB driver.  I can connect to the board using ST-Link Utility.

Hello ST Community,I am currently using the EVSPIN32F0251S1 inverter board to control a BLDC motor in an elevator door control application.When I run my BLDC motor in torque mode and set torque with this api  MC_ProgramTorqueRampMotor1_F() so my motor is rapidly rotating and after 1 second it will give me startup failure error.Thank you in advance for your support. Best regards,Vedant Kachhadiya

For PID tuning, from documentation, I understood how to calculate gains for current loop. But how to calculate them for speed loop? How Motor control workbench is auto calculating the gains for speed regulator? Please provide documentation or formulas related to it. 

Hi Expert, I wan to use STM32303E-EVAL + STEVAL-IPM15B 3Sh to run the motor profiler 5.4.8.But the error message is shown below.I connect the control board to PC via USB, the LD8 is red. The device manager of PC cannot see com port. I think the STM32303E-EVAL not provide a virtual com port, right?How could I solve this problem?Thanks. 

I saw in a post here that someone blew up their B-G431B-ESC1 with just 5As using the motor profiler. The spec says the mosfets will output up to 120A. I am looking to run motors up to 30A. I'd like to see if there is a prescribed way of adding heat sink & fan to controller board. 

Hello,We are currently in the testing phase with the EVSPIN32G4 board using the various available software suites.After upgrading to the following latest versions:MC Workbench 6.3.2 → 6.4.0STM32CubeMX 6.??.? → 6.15.0STM32CubeG4 Firmware Package V1.6.0 → V1.6.1I created a project in MC Workbench for the EVSPIN32G4 board and generated the project for CubeMX.To my surprise, the microcontroller is no longer the correct one in CubeMX, even though it worked fine with the previous version.The evaluation board uses a 64-pin package, but the automatic configurator now selects a 100-pin package instead.I tried rolling back the software versions, but nothing seems to work: the package remains stuck on 100 pins.Do you have any idea what could be causing this issue?Thank you in advance.

I'm trying to program the EVSPIN32G06Q1S3 to run a PMSM, but I attempted to use STM32CubeMX to help with the pinouts and code. The problem is that I can't find the EVSPIN32G06Q1S3 in the board selector. Is there a way to download then import the board information to STM32CubeMX? If there's not, could I get documentation to help implement the board through the MCU selector? Thank you!

Hi, I'm working on a project in MC Workbench 6.3.2 and trying to configure a motor with a maximum speed of 150 RPM. When I set the "Max. Application Speed" parameter to 150 RPM (as shown in the first picture), I encounter an error related to the "Speed Sensing Configuration". I've attempted various parameter combinations for the Hall Sensor settings (as shown in the second picture), but haven't resolved the issue. Could you please advise on how to fix this problem? Thank you for your help.

I dump a STEVAL-SPIN3204 board in STMC Board Designer and want to add "Electronic Speed Control" Feature.In Board Designer I had add this feature without error. But in Motor Control WorkBench as attached 1.JPG .We can see ESC feature. But in project config stage, we can't find this feature as 2.JPG. Can anyone help on this question ?

Hello STIm trying to generate a HSO compatible FOC board using the STM32G747CEUx but I am not able to select the HSO option for Speed sensing.I've seen the requirement of using atleast two different ADCs for the current sensor and voltage measurementTherefor I have assigned ADC1 and ADC2 for current measurementAnd ADC3, 4 and 5 for voltage measurementBut I am not getting a solution for this.Here is my json design fileThank you"mcu": "STM32G474CEUx", "clockFrequency": 170, "motorDrives": [ { "name": "M1", "minRatedVoltage": 16.9, "maxRatedVoltage": 60, "maxRatedCurrent": 80, "maxRatedPower": 2000, "features": [ { "type": "CurrentSensing", "name": "CurrentSensing", "hwVariants": [ { "signals": { "CURRENT_AMPL_U": [ { "name": "PA0", "help": {}, "cost": 0 } ], "CURRENT_AMPL_V": [ { "name": "PA1", "help": {}, "cost": 0 } ], "CURRENT_AMPL_W

We are using MCWB 6.3.2We generated a project that is working fine. However, testing our motor close to its peak current, we have been getting an over current fault.We decided to increase Over current protection (OCP) Digital Filter Duration and Threshold (well within our system limits). We then go to 'Project HW & Info' and Run CubeMx. From there we generate the project.Our main.c file is intact as well as the peripherals and pin configuration. However, we are not sure that the Digital Filter Duration  and threshold have been updated.Would you please, confirm that this is the correct workflow and where in the code I could confirm that our changes made through? We read somewhere that topology changes are not possible at this point, but this is not considered a topology change, correct? For us to generate new project every time would be very laborious giving that we have an extensive use of peripherals.Would it be possible to turn OC protec

Hello ST Team and Community,I’m working with the X-NUCLEO-IHM07M1 board for 6-step sensorless BLDC control, and I need some clarification regarding the purpose and correct use of the GPIO_BEMF pin.In this ST Community answer, it is mentioned:"The GPIO_BEMF pin is provided to manage the BEMF sampling during the PWM ON state for 6-Step control only."I understand that this refers to enabling the BEMF voltage divider (e.g., 10k/2.2k) to bring phase voltage into the ADC range during PWM ON time. However, on the X-NUCLEO-IHM07M1, it seems that even during the PWM OFF time, if GPIO_BEMF is not pulled LOW, the voltage divider is disconnected (floating bottom resistor), and the BEMFx signal becomes unreliable or unusable for ADC reading.

Hello,      I use MCWB 6.4.0 & Motor Pilot 6.4.0, STLINK V3 MINIE.      Motor Pilot can not discover STEVAL-CTM010V1 board.      And  I find that MCU can receive datas at buadrate 1200 to 14400, but failed at 19200  or  more fast .      Does the STEVAL-CTM010V1 support 115200 baudrate ?  Or PC817B doesn't  support this baudrate?       this issue seems like this one, https://community.st.com/t5/stm32-mcus-motor-control/steval-ctm010v1-board-can-not-work/m-p/241708#M4301
