STM32 MCUs Motor control

Hello,I have intsalled the motorbench version 6.2.1, and I have already the cubeMX version 6.9, but when I'm using the motorbench and trying to open an example for the steval-spin3201, it's working until I reach the generate program and it's saying after that the cubeMX is not found or intsall a higher verison, I tried to uninstall and download again but it doesn't work, also try to change the directory also it's not working, so please if anybody have suggestions or feedback about how to solve this issue, please provide it to me.Thank you.M.Nasser, 

Hi team!I testing MP6530 three-phase BLDC pre-driver with STM32G474RE.This drive's gate drive need to control like below.I wrote a code that uses commutaion interrupts.I have attached the test code, so please see the code for details.And the problem is that I want to set the EN signal to high when outputting PWM, but I cannot set it to high.I want to set EN signal to high like fig1.PWM signal is assigned to CH1, CH2, CH3 of TIM1.EN signal is assigned to CH1N, CH2N, CH3N of TIM1.fig1. Is there a way to set CH1N, CH2N, and CH3N to high during PWM output? 

Hello Team,  We want to develop a BDLC driver with high power. We went through the below product, it matches other requirements except for output current, it is only up to 1.5AMotor Control Nucleo Pack with NUCLEO-G431RB and X-NUCLEO-IHM16M1can u suggest a similar module that can support high voltage of up to 60V and a current of up to 20A.it should be able to operate sensored and sensorless  and also on encoder feedback. Regards,Sayali 

What is the meaning of the five different rev-up (start-up) phases that one can set up in sensorless mode?From my experiments, I figured that Phase 1 is alignment and Phase 2 is an actual startup phase. Is this correct? What are the other phases for? Where is this described? Secondly, I'd like to debug the startup procedure as we're having some issues there.For this I'd like to graph the phases inside the Motor Pilot.Which Parameter do I have to add for this?

HiI am struggling with the appearance of my BEMF in my 6 step control.The picture shows one of the phases. And according to all the documentation I've seen ( and I have read a lot ) my BEMF goes the wrong way. The BEMF looks like outstanding ears but it should look like hanging dog ears ( hope that made sense).I hardware is homemade running a STM32G474.  The PWM is unipolar i.e the lower mosfet is on, during the step, and the PWM is done with the upper mosfet. At this stage I am bit-banging ( very temporary of course) the PWM so that I have 100% control of the ON/OFF-state of all 6 mosfets. I think my plan is to detect BEMF during upper mosfet On-time compared with virtual GND.Any thoughts why my BEMF goes the wrong way is appreciated.   

Hello,I am aware of the MC SDK by ST, which is for BLDC / PMSM motor control.I was almost sure I saw some package from ST for stepper motors (2 coils, 4 wires) some time ago, but maybe it was by someone else and I remember it wrong.... Anyway, I haven't found it, though as a non-native English speaker and only slightly familiar with motor things, I might be using poor search terms...Is there an official ST "library" to control steppers on an STM32?Or something by a 3rd party that's recommended? By ST, or veteran users perhaps :)Regards

I have over current protection like this in my custom board how can i implement this on motor control workbench here is my file and i'm getting eror when i try create with six step 

Hello!I'm having some issue while updating the deadtime of the PWMs on Advance timer TIM1 during PWM operation is running.I'm attaching the scopeshot with the Channel 1 and 1N pulses, during deadtime register(DTGbin) update ,the deadtime is zero. In the scope shots we can see the dead time before and after the deadtime update where the CH1 signal stays high for a longer duration, the pulses also seem to cross (x) switch at the wrong time also. I observe this happening at some deadtime updates but not every update.Would you know why it does this or how to fix it?My application needs to have large deadtime in the PWMs during startup which I ramp down to small value during normal operation to limit the current in converter.Thank you, Here is the configuration of the Timer 1 for the PWMs ( i have 3 channels but could only capture 1 in scope)/** * @brief TIM1 Initialization Function * @PAram None * @retval None */ static void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init

Hello,I have a circuit which uses the L6470 with a STM32F401.  I based the circuit off of the development board, X-NUCLEO-IHM02A1 which has 2 L6470's on board.  https://www.st.com/en/ecosystems/x-nucleo-ihm02a1.htmlThe X-NUCLEO-IHM02A1 circuit has a large cap on VS.  The documentation on the X-NUCLEO-IHM02A1 states the power supply can be between 8 and 45 V.  Our circuit is to be used at 24VDC.  The large cap on the X-NUCLEO-IHM02A1 (C7 and C23) is listed as 100uF and 63V.  On my design, I am using 100uF 50VDC.  We built some units and supposedly the units were in service for a period of time but then at some point failed.  I received two boards back that show damage to the L6470 and the large cap that would be on VS to ground.  The L6470's show burn marks on the top of the chip and on board the large electrolytic cap was blown off of the board.  When I checked the cap for resistance it read nearly a short (just a couple ohms).  On

Hello, Hardware : NUCLEO-G474RE + X-NUCLEO-IHM08M1 + DollaTek 2204 BLDC motorSoftware : Motor Control Benchwork 6.2.1, STM32CubeIDE 1.13.1 When I try to start motor profiling the motor starts to produce radom beeps, vibrations and accidental spins. The profiling reaches 28% and then the motor stays in that state forever. What can I change to make the motor rotate correctly and to finish profiling successfully?

Hi,I am trying to create a User Application where I pass in commands from a terminal application (ex: Putty or Ucon) which results in the motor doing something.I have configured the MC Workbench with the following options:   Not using the MC Pilot so I have the following in User Interface: For the first part of the application, I was passing 'SH\r' to start the motor and 'MO\r' to stop the motor.The code in main.c is as follows:  #define BUFFER_SIZE 3 uint8_t data_buffer[BUFFER_SIZE]; main() { // auto generated code ... HAL_UART_Receive_DMA(&huart1, data_buffer, BUFFER_SIZE); while(1) { } } void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if(huart == &huart1) { if(data_buffer[0] == 'S' && data_buffer[1] == 'H') { MC_StartMotor1(); } else if (data_buffer[0] == 'M' && data_buffer[1] == 'O') { MC_StopMotor1(); } } }​  The Motor Holds a position (not sure what is the default position set to?)

Hello all,I have developed a custom control board and a custom power board. I am trying to add them to MotorControl Workbench 6.1.1 and I have written a custom JSON files describing both board. A few interesting things:I am using STM32G431RBT6 as my MCU, the NCP51820 is gate driver and the current is measured with ACS772ECB hall effect current measurement IC. And the this is how it is connected to the MCU, most important connections are marked in red. I am getting ErrorThe hardware selected is not compliant with the selected algorithm. Please review your selections. When I try to start a project. I have made a two decisions because I did not know what else to do.The first is I can't see how to add e custom connector, so I used  MotorControlConnector type.The second is I can't see hall effect sensor type for current sensing and I chose ThreeShunt_RawCurrents_SingleEndedCan anybody tell me what I am doing wrong?

Hello, I am working on a motor control project that is to be driven battery-powered. This means that the DC current has to be monitored in order to avoid overloading the battery. I have made a Control Loop which takes in a DC Current reference as input and adjust the torque. The Current Calcuation is derived of the power calculation for the dq-framework.P = (id*vd+iq*vq) * Conversion_Factor ... (I am using the standard power calculation provided by ST)My Problem is that the Internal Power Calculation doesn't match with the external power measurements from the power-supply. Take a look at the following signals:Internal Power CalculationInternally measured power, W (red)Power Supply MeasurementExternally measured power, Pin (orange)The main problem is that (Pin) isn't held stable (flat at ~160W). What could the reason be for the difference between the internally measured power (W) and the externally measured (W)?Best Regards NikolajInformations:Motor: BLDC with H

I am trying to create a new project for Nemo 23 PMSM with STM32F303RE control board and X-Nucleo-IHM08M1 power board but while creating new confirugation for my motor getting frimware error.Can anyone please help to resolve the issue.ST Motor control work bench version: 6.2.1 

Hi thereI am using a B-G431B-ESC1 board with a BLDC motor with hall sensor.The project is generated MC Workbench and is working just fine.Now I need to know the number of revolutions that the motor have taken since it was started (for application purposes). Since the setup is with a hall sensor, this information must be available somewhere but I cannot find this information in the MC_Api. Any ways to obtain this information?

Hi,We have encountered another problem. When the potentiometer voltage level is increased, the motor speed increases smoothly. However, when the potentiometer voltage level is decreased, the motor suddenly stops and displays an overvoltage error.How to fix this?Thanks Mathan

Hello. I have developed a custom control board utilizing similar architecture to that of the STM-B-G431B ESC board. I am experiencing difficulties trying to tune the PI coefficients for current Iq and Id. The output plot from the motor pilot looks really noisy. I tried playing around with the coefficients, but I can't seem to stabilize the current readings. Could there be something wrong with my project configuration in the motor control workbench? Im using the YAGEO - PS0306FRL7W0R003L as my current sense resistor. 

I'm trying to control the AirFan MFA0290 BLOWER using the ST motor control SDK V5.4.8 and the generated pulses on the Phases and Halls are as pictured below (brown, red, orange ) (phase 1, phase 2, phase3) respectively but i need to make those pulses to be as follow :but I don't know what I need to change to be able to produce that sequence.and this is my motor parameters :find attached the motor data sheet 

Hello,I want to ask a question about internal buck switching converter of STSPIN32G4.We want to use its output voltage of 10V or 12V to supply an external potentiometer.Is this converter indicated to use for power supply external devices requiring 10mA about? Thank you in advanceBest Regards,Federico Flammini

Hello,I am currently trying to implement an ASPEC Controller in C# to communicate with a motor control dev board over the UART (essentially, creating motor pilot with the ability to modify as needed).  So far, I have implemented Beacon and ping packets.  Beacon packets work perfect.  When I do a ping packet, the return data seems garbled. The code is designed to not process any packet that doesn't have a valid header CRC. I tested this by manually corrupting the header, and I no longer saw output from my packet detection, which suggest to me that I am receiving what the devkit is trying to send.I programmed my code to output debugging information every time a valid packet is sent or received.  I have attached the output of my code.  It starts with 2 pairs of beacon packets to negotiate buffer sizes.  I then start sending 4 ping packets per second with consecutive packet numbers.For the ping packets, I am expecting to get back the same packet, except f

Hello,I have tried multiple times to connect a Nucleo-G4R31B to the motor profiler.The software fails to recognise the boards at any of the preset baud rates.The board is recognised by the computer and is visible on the device manager. It is also programmable through STM32CubeIDE and STM32CubeProgrammer. I have tried changing USB ports but haven't had any sucess. The version of the motor pilot is V1.2.5 and the motor workbench is 6.2.1.My aim is to profile a BLDC motor and then test out control algorithms. Please let me know what I'm overlooking.  I have attached the terminal messages and the related screenshots. 

I can't create a motor profile in MCSDK Workbench. I'm getting an error like the one below. What is the reason for this?
