Hi @cedric H,mcsdk has current control.speed control.position control.How to add power(input power or output power for example 1000Watt) control?thanks

I have a motor control application generated with MCWorkbench and am successfully using it on my custom board. I added many custom features to the application such as CAN Bus, absolute encoder and my own position control to suit our application. TI am handling different encoder configurations with #ifdef directives.This firmware works great but I need to use it with a few different motors.So what would be the simplest way to modify the application to handle multiple motor profiles and PID gains in the same file?I don't think the mc_api.c has provisions for that. So I noticed that mc_config.c parameters are already available in main.c so I could change them directly. I considered including drive_parameters.h and pmsm_motor_parameters.h to re-define those parameters in main.cThank you in advance!

The B-G431B-ESC1 controller works with a high-speed BLDC motor (4300KV at 12V). The motor and all parameters of regulators have been properly configured, because during motor tests at idle and under load, the motor behaves correctly in full range of speed - ESC controlled via UART from the computer. When the ESC is controlled via PWM (490 Hz, 1060 - 1860us) after exceeding 32,768 rpm, the reference speed is suddenly set to minimum (1000 rpm). Due to the characteristic value - 32,768 (maximum int16 range), I suppose that the variable is overflow and the minimum value is set. I use X-CUBE-MCSDK-6 (ver. 6.1.0) to generate all the code and I don’t make any modifications to it. Can anyone help locate the variables that might affect this?

I am controlling a DC motor, I want to synchronize it with another motor so I have to vary quickly the value of duty cycle, who can help me, I used the simple generation of pwm but it did not work

I did connected the board to PC with USB2.0 cable, and I suuplied 24V DC to the board(STEVAL-SPIN3204) and set the baudrate to 9600 bps, ​ still this problem happens.

Hello,I'm using bldc motor. Battery Voltage is 40.4V. I run the motor on no load the battery voltage is 40.4V and when I apply the load the voltage is dropping.load(current) is 1A & voltage is 40.3V load(current) is 2A & voltage is 40.2Vload(current) is 3A & voltage is 40.1Vload(current) is 4A & voltage is 39.9Vhow to slove this problem if any one know help me.

It tells serial doesn't work well,and I test it throght my serial application,it works!So who can tell me what's the matter?I found my nucleo-f401(rev C01) don't have external crystal oscillator,and the rev-C04 and rev-C04 all have a external crystal oscillator,So I want to know This software(MCSDK Motor Profiler 5.Y.2) download the binary used external crystal oscillato?

Hello.We want use a Stepper X-NUCLEO-IHM14A1 with STSPIN820. We need to drive the STCK signal on the PB3 or PB10 GPIO. because we need some RAM and a CAN BUS, we choosed the STM32F446 (nucleo 64 board).Each step will have different time, so we want to use DMA to timer. PB3 is used by SWO and there is only TIM2_CH3 on PB10.I have found this tutorial : https://controllerstech.com/interface-ws2812-with-stm32/and after changing the destination register CCR1 by ARR, it works fine... on the Timer 1 CH1.But, we can't do the same on TIM2.TIM1 CH1 is on the DMA2 / CH6 / Stream 1TIM2 CH3 is on the DMA1 / CH3 / Stream 1Is there any difference between TIM1 DMA2 and TIM2 DMA1 ?

void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim){ if(htim->Instance==TIM1){ if (htim->Channel == HAL_TIM_ACTIVE_CHANNEL_1) { if (Is_First_Captured==0) // if the first rising edge is not captured { IC1_Val1 =TIM1->CNT; // read the first value of the first sensor Is_First_Captured = 1; // set the first captured as true } } if (htim->Channel == HAL_TIM_ACTIVE_CHANNEL_4) { if (Is_First_Captured1==0) // if the first rising edge is not captured { IC2_Val1 = TIM1->CNT; // read the first value of the seconde sensor Is_First_Captured1 = 1; // set the first captured as true } Is_First_Captured1 = 0; // set it back to false } }}// synchronize tow motorssync_motors(void){ time_diff = IC1_Val1 - IC2_Val1; // Si le capteur 1 a été activé avant le capteur 2, on augmente le PWM du moteur 1 if (time_diff > 0) {   sync_error = time_diff;   // Augmentation du PWM du moteur 1   motor1_pwm += 0.1*sync_erro

Hi I have succefully generated code and downloaded it. I run the programm in debug mode but my EVSPIN32F0601S1 Board cant be regonized by the MotorPilot 6.1.1. I tried also with the 5.4.8 versions but then i cant genered the code. So what i can do now ?

Hello everyoneIn my Motor Control application I use low side active low gate driver L6398. Because of the shortage of this component, we need to use L6399 in which low side gate driver is active High.We developed application using Motor Control Suite (5.4.1), and we use STM32F303 uC.I've tried to change polarity of the CHxN in MX_TIM1_Init() but it doesn't work: every time a start the motor I get Over current error. The changes I made are in boldBefore (L6398 Gate Driver) sConfigOC.OCNPolarity = TIM_OCNPOLARITY_LOW;After (L6399 Gate Driver) sConfigOC.OCNPolarity = TIM_OCNPOLARITY_HIGH;Obviously I change polarity for all 3 channel.I've tried to change Idle state too from sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_SET;to sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET;but never changes.Do I have to change something else? Do I have forgot some other changes to do?Many thanksRoberto

Hi all!I am trying to control a motor with integrated hall sensors using the B-G431B-ESC1. I've had a lot of problems, getting all kinds of errors while setting up the firmware, but I managed to control it through the motor pilot.Now I would like to control it with a PWM-input onto the board pin but as soon as I configure the hall sensors in the example project it stops working correctlyAll in all I'm a bit baffled at how hard it is to get anything to work the way you want even with fresh installs of all the software.Anyway I'm using: MC Workbench SDK 5.4.8CubeMX 6.3.0CubeIDE 1.12.0CubeProgrammer 2.13.0If anyone could help me out here I would be very thankful!

Hi, is there any particular option for internal rotor motors with the ST motor control suite?

This PWA is running multiple BLDC motors. we have some serious noise issues on the ground plane, but want to understand what we are seeing. this is the output of PD2, configured as an push-pull output (driving an LED w/ 20k resistor to ground. when running the motors, we see this on the pin. when the motors are off, it's a steady high signal. We are also seeing this on other various IO pins. The 3.3V / DGND at the processor is stable. Can't share any schematics/layout etc. but we know the noise is due to the motor switching We don't see any transients below 660mV (where the ESD diodes turn on) and these transients are very short 10ns [not ideal obviously]. It could almost be explained where the high side output FET is getting turned off and the low side output FET is getting turned on, then quickly being released and the output being switched to OD. alot to get corrupted, but maybe not! Would this be caused by some power transient on the pins or DGND or what? thanks!

I'm using motor control hardware very close to NUCLEO-G431RB with X-NUCLEO-IHM08M1 3Sh. It has only a bit different bus voltage and current feedback scaling resistors so I was able to spin the motor it with the motor profiler. The results were quite close as measured, RS=0.1 ohm and LS=0.08 mH. So I know that the hardware works.Now when I configure the parameters in the MC Suite, it results in around 50% constant PWM phase output, exactly same for all U, V and W channels. Which obviously does not make any sense.. At the end there's an oscilloscope picture of U and V running at 10 kHz. Same figure is acquired with 30kHz too.If I raise the inductance value closer to 1 mH, the PWM starts to get correct shape, but this is too big of an inductance value to make the motor spin, it just does not work. I tried to chase the possible bug/problem/issue where the PWM is configured according to the parameters derived from LS, but this seems to end up in the libmc closed library...I'm using the late

Hello,I am working with a NUCLEO-F446RE development board and an X-NUCLEO-IHM06A1 motor control board to control a stepper motor.An example project (STM32CubeExpansion_SPN6) is given with the motor board. However, I want to modify this project to add two PWM outputs and UART communication.Normally I would do this by modifying the .ioc file, but it is not provided in the example project. Is there any way to recreate the .ioc file? If not, how can I do the PIN configuration? What are the names of the files in which this configuration is found?Thanks in advance,Best regards,Yoan

Hi,Currently I am working on two wheeler project with QS motor 2kW, for development purpose I use STEVAL-CTM009 and Nucleo-F103RB. I use lab bench supply (30V,3A) as VBUS.I tried to driving the BLDC with sensorless algorithm but after few seconds the fault occur (start-up fail or speed fedback)Really appreciate any help and advice.Here is attechemt of my configuration

The motors (being controlled) will eventually be used in a man-rated system. We know this EVSPIN32F06Q1S3 reference design is for unmanned systems like drones, but we plan to start here. Do you know of a chip and reference design that is better suited to man-rated flight hardware? Each of our 4 motors uses (maximum) 15kW at 200VDC, hopefully 100A. Each motor has 3 motor controllers configured in a fail-over cluster. So 12 motor controllers per aircraft.

I am bit confused with ADC interrupt code generated for my project compared with the code generated from the motor control SDK for the evaluation board B-G431-ESC1.For my generated code void ADC1_2_IRQHandler(void){ /* USER CODE BEGIN ADC1_2_IRQn 0 */ /* USER CODE END ADC1_2_IRQn 0 */ HAL_ADC_IRQHandler(&hadc1); HAL_ADC_IRQHandler(&hadc2); /* USER CODE BEGIN ADC1_2_IRQn 1 */ /* USER CODE END ADC1_2_IRQn 1 */}The  HAL_ADC_IRQHandler(&hadc1); HAL_ADC_IRQHandler(&hadc2); are generated, but for the motor control SDK i find it void ADC1_2_IRQHandler(void){ /* USER CODE BEGIN ADC1_2_IRQn 0 */ /* USER CODE END ADC1_2_IRQn 0 */ // Clear Flags M1 LL_ADC_ClearFlag_JEOS( ADC1 ); (void)TSK_HighFrequencyTask(); /* USER CODE BEGIN HighFreq */ /* USER CODE END HighFreq */ /* USER CODE BEGIN ADC1_2_IRQn 1 */ /* USER CODE END ADC1_2_IRQn 1 */}I understand the  (void)TSK_HighFrequencyTask(); is
