STM32 MCUs Motor control

Hi, I'm not seeing the 5 revup configuration slots I should be seeing? It was fine the first time I did this.

Why do I see an overcurrent error in Motor Pilot when trying to configure my boards for FOC algorithm? I am using the 3-shunt configuration with Hall sensor.

I am using the custom board based on B-G431B-ESC1 and the same software, but i am struggling to go beyond 10NM torque i am really not able to understand the root cause of the issue. One observation is the Valpha and VBeta is going beyond 28000. Is that the reason? Please help. What are the other parameters i have to look for?

I wanted to know if there is any enable pin or some code that needs to be followed before toggling the pins that are going to the gate drivers.

Hi all,I'm currently having CTM007V1 driver board for motor control application. the control board is stm302r8 MCU and the driver board is STEVAL - TTM001V1. can i use modify the CTM006V1 firmware and replace it with CTM007V1 firmware? Regards, Siva.

Hi,When I flash a code that contain to start the motor (MC_StartMotor1) or press start on ST Motor Pilot, my motor doesn't manage to rotate on its own. It's like it is stuck and need help manually to finally be able to spin. Any idea what could be the issue and how to solve this? 

Hello,I am using Timer 1 for the generation of 3PWM and their complimentary Signals and I am getting all 6 PWM waveforms.For six step commutation I need to add phase delay between the channels of the timer. Is it possible using any HAL function? I am not using any motor control library or example code. Can anyone guide me. Regards,Ajish Saji

Hi guys, I'm new on this forumI'm using the MCWSDK v5.4.8 to drive a custom control and power board on a big Hub motor (17" from YM) using hall sensors.The simptom I'm facing is that every time I try to start the motor with a command as MC_ProgramTorqueRampMotor1 or MC_ProgramSpeedRampMotor1 the motor tries to start. It starts, turn for close to 1° and then abruptly stop right after.I get a MC_SPEED_FDBK right after, because this event pulls lots of current from the power source. The power source protects it by cutting of the supply thus powering off the hall sensors.While investigating the problem, we disconnected the phases wires and just connected the Hall connections to check the SVPWM signals for each sectors, by turning the motor by hand. We noticed that in some of the sectors, there is only one phase with a PWM signal while the other ones are either fully open (0% duty cycle) or fully closed (100% duty cycle) in a fashion that while one phase is open, the other is clos

Hello, when referencing a position control with a new custom hardware, there is a short circuit of the power supply at the beginning of the referencing. The STM32 G4 with the MCSDK 5.4.8 is used. The setup already ran on a first own board so that the parameters worked so far. Only a new gate driver with integrated current amplifier was used. The assumption is a faulty current amplification. The TI DRV8304H is used and the circuit is designed regarding to the reference design. Is the internal amplifier circuit compatible with the MCSDK at all? If there is any experience, I would be very pleased about. Thanks

Hello,I working with a motor that has very few info : motorBased on the picture, to do the profiling (in ST Motor profiler) of this motor. Pole pairs : 42Max speed : 600Max current : 5AVoltage : 24V but the application show 23V (therefore 12V as under voltage threshold and 28V as over voltage threshold)When I connect the device and start the profiling, after few moments, the profiling stops with orange over voltage error. I guess it's more a warning than an error but where this come from and how to not have it anymore?I'm asking this because it seems that ignoring the very first step in my project bring me more troubles

Hi all.I develop controller for PMSM motor and got a problem as below:Some time MCU jump to hardfault handler. In debug, I see that it cause from random point (different from time to time), some time it cause from very basic function (such as sinf(), cosf(), delay..), as belowdisassembly at <signal handler called>() at 0xffffffe9 as below:"ffffffe9:   Failed to execute MI command:          -data-disassemble -s 4294967273 -e 4294967413 -- 3          Error message from debugger back end:          Cannot access memory at address 0xffffffe8" I also think it may cause from hardware because inverter may generate lot of noise. But whenmeasure noise in power, clock of MCU, it is clean: as belowWhen hardfault about to occur, the debug connection on cube monitor corrupt many timeSo, where I can check for this issue?Thanks

Hello,Level : beginnerHardware : NUCLEO-F302R8 + X-NUCLEO-IHM08M1 + Qmot BLDC motorSoftware : Motor Control Benchwork 5.4.6, STM32CubeMX 5.6.0 and STM32CubeIDE 1.12.1I'm trying to follow this tutoriel : STM32StepByStep:Getting started with Motor Control - stm32mcu (stmicroelectronics.cn)First issue : when I try to use the ST Motor Profiler and click on the start profile button, I can't complete it because my board start smoking and the process stop because of overheating fault. What's the reason of that?Second issue : I open ST Motor Control Workbench to create a new project. I select Single motor as System,  Custom as Application Type, Power & Control as Selected Boards, NUCLEO-F302R8 as Control Board, X-NUCLEO-IHM08M1-3Sh as Power Board and Generic lov voltage <= 50V as Motor. I change the motor parameters, more precisely Electrical Parameters : 4 as pole pairs, 4000rpm, 5Apk, 36V, 0.35Ohm, 1mH and I leave the B-emf constant as default because I don't know what

Using the SDK I am basing a new system on the EVSPIN32G4. After selecting the inverter, and motor, I am then taken into the parameter configuration of the motor driver.According to the boards manager the EVSPIN32G4 has multiple configurations available for single ended and differential current shunt configurations, plus using 3 op-amps, one for each current shunt etc, for the most system flexibility. Yet in the parameter configuration section of the SDK, when selecting this board, you have no control over the configuration of the current shunts and are locked into a single ended, triple shunt, system using only two op-amps. You can select to use either internal (PGA), or external resistor configurations but that's it. Moreover a triple shunt, triple op-amp, with external resistors, is the default hardware configuration for this board, so selecting something other than this (such as using the PGAs) should require hardware modifications but the SDK doesn't think this is necessary.Th

There are actually a lot of problems. 1- I create a new project and the V/F control selection does not appear. I'm just coming across FOC and 6-step control options. 2- When I create a project related to FOC, I cannot select the ICS sensor option. When I want to create a custom board to overcome this, I can't find any information about json codes.This version is good as an image, but functionally the promised features are useless.If I can't see something, please someone teach me how to select the ICS sensor for the FOC option, how to create a new project for V/F, and how to use the board manager.

I am using an e-bike motor 48V350W with an EVALSTDRIVE101 3Sh and NUCleo F401REboard to do some tests. The motor only starts the first time I press start and then if I stop it doesn't resume rotation unless I restart the Nucleo board. I analyzed the current and it seems a very low current passes through the motor, but is not sufficient to make it rotate. on the eval board also a red led turns on. Why do not resume rotating at the level I choose?

I use TIM2 in Hall Sensor Mode andI want to use the unused channel 4 for PWM generation.There are no conflicts in CubeMX configuration.Are there any problems with the actual operation? 

Hi ,I am using stm32wl55ccu 48 pin QFN MCU to drive a 3 phase brushless motor using 3-phase complementary PWM output signals using TIMER 1. I have seen at the datasheet that this 48 QFN package is missing the complementary output of TIMER1 ,Channel 3, TIM1_CH3N (which is present at the BGA version). Is it possible to generate the 3-rd phase complementary output PWM signal in another way ?(like using timer 2 in a master/slave configuration).Thank you, Joe.

Can STEVAL-ESC002V1 be applied in a electronics of quadcopter? For example, is it possible to connect to betaflight FCU or Pixhawk?

Hi,I am using MCSDK6.1.2, STM32CubeMX6.8.1, and STM32CubeIDE1.12.1 to make a control for 24v 8-pp motor with hall sensor. Motor pilot 6.1.2, Motor profiler, and 24v motor works well on NUCLEO-STM32F302R8 and X-NUCLEO-IHM07M1. I prefer to use the function void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) to handle the command data(maybe use if else function to identify the command data to enable MC_StartMotor1(void) or change the hFinalSpeed value in void MC_ProgramSpeedRampMotor1( int16_t hFinalSpeed, uint16_t hDurationms )) to control motor rather than Motor pilot 6.1.2. Because I still can’t understand how to use the MCP command ID to use the command in mc_api.c even though I have read ASPEP document. So I make some modification on void USART2_IRQHandler(void) in the stm32f30x_mc_it.c. I have modified USART2_IRQHandler(void) (by commenting all code generated by STM32CubeMX and adding HAL_UART_IRQHandler(&huart2); and printf("Hi!\r\n");  for testing wheth

Does MCSDK support hrtim?

Is there a parameter where I can set the motor speed so that when the board is powered on the motor starts at a given rpm?I am fairly new to this but have managed to get a motor profile and generated a code but my knowledge stops there.board: B-G431B-ESC12-pole motoropen loop, no sensor.

Hello,I am trying to build a BLDC controller using STM32F4. I made a board with the 6 mosfet and drivers, current sensing, Hall sensors input...Is there a ST library for motor control ? I found differents tools (MC workbench), but they seems to be dedicated for evaluation boards. I'm using STM32CubeIDE.Thanks for your help,Best regards
