I am using ST’s Motor Control Workbench (MCW) version 6.3.2 to control a sliding door. I am using PMSM as motor and FOC as control method. PMSM has 10 pole pairs and there is a 1024 ppr incremental quadrature encoder on it (has not index pin). I am using Nucleo-G474RE, STEVAL-IHM023V3 and X-Nucleo-IHM09M2 boards. I am having trouble with encoder alignment. if I'm not mistaken, ST MCW uses “move till aligned with phase A” method (see attachment) as the encoder alignment. But i have a mechanical limit and this will not allow the motor to perform the needed alignment movements. I have posted this in the motor control forum. Not answered yet (https://community.st.com/t5/stm32-mcus-motor-control/incremental-encoder-alignment-problem/td-p/775343) Does ST have any plans to update MCW software to include the motionless start method into speed sensing configuration in the near future? Can anyboady give/share source code/flow chart etc.? Any information you provide will be gl

About EVSTSPIN32G4, I started the code generated by MotorControl Workbench 5. Y.3 normally.If you transplant the IIC configuration of the pre drive and enable PWM output, the VDS will report an error.After carefully reading the generated code, it is found that before PWM complementary output, the lower tube is opened for charging, and the output PWM pre drive or VDS protection is written. Is there a routine for STSPIN32G4 IIC to configure PWM output?

[PN]: custom Board based on evspin32g4-dual[VERSION]: 6.4.0[Motor]: Xing2207 1800Kv[CubeMx]:6.14.1Hello,I have a problem with getting my FOC BLDC motor to start, the specs of the motor are: 0,08Ohm 50uH 0,32Vrms/kRPM. My project is for two sensorless motors with one shunt each, but I am trying to get started with the one connected directly to the stspin32G4.When using 10kHz Pwm the motor first vibrates but does not spin, then it starts accelerating, then I get the startup failure. The failure always occurs when it reaches the start-up speed threshold. When I try 40kHz PWM it wont start at all. I noticed that in cubeMX there are some errors.The schematic for the mosfet drivers is identical to the evspin32g4-dual:33Ohm gate resistors and 1uF Boot CapI set the Boot charge time to 50ms and the Charging Duty cycle to 15% Below is a screenshot of the startup phase once the motor is running, orange: one phase, blue: voltage over shunt, the digital signals are the gates of all t

Hi there,I am currently trying to create a custom power board in the Board Designer software and I am running into issues. I am using the NUCLEO-G431RB as the control board. In the designer for my custom power board, I have configured pins PB4 (MR27), PC7 (MR19) and PB0 (ML34) as Phase Voltage Generation Pins using the configuration "Driving HighSidesAndOneEnable". When I then try to configure a project, in the project creation phase I get the error "DrivingHighSidesAndOneEnable: No timer matches all signals requirement". However according to CubeMX, on the STM32G431RBTX MCU, all those pins are connected to three TIM3 channels respectively. Not sure where I am wrong, any help would be appreciated thank you. Additional Info:Version: 6.4.1Tool: MCSDK - Board Designer/Project CreationHow to Recreate: 1. Open the Board Designer and try to create a power board2. Configure the Phase Voltage Generation pins as states above3. Configure the Current Sensing Hardware config with other a

[PN]: EVSPIN32G4-DUAL[VERSION]: MCSDK 6.3.2[TOOL]: Firmware[DETAILS]:Hello,I am working on a dual-motor application using the EVSPIN32G4-DUAL board with MCSDK 6.3.2.I observe the following behavior:when both motors are running at the same time, the speed regulation is stablewhen only one motor is running, strong speed oscillations appearThis behavior is observed when running either motor alone. In other words, the issue does not seem to be linked to one specific motor channel.The motors are custom motors designed/manufactured by us, with the following configuration:5 pole pairsRs / Ls identified with the profilerHall phase shift = 121°Rotor angle measured using Hall sensorsPWM frequency = 16 kHzThe attached speed plot illustrates the issue:first phase: only one motor running → oscillations visiblemiddle phase: both motors running → stable behaviorlast phase: only one motor running again → oscillations visibleThe current regulator seems very stable, only the speed loop is going crazy wh

I am using Powerstep01 for stepmotor driving , comminucate with stm32H743 via SPI , and using x-cube-spn3's firmware for testing (IHM03A1_ExampleFor1Motor), but after initial function running , motor can not run. and after reset the power , powerstep01 is alway burned out .   below is the schematic , Does someone could help to check what's the issue ? (VS=24V , VCC=3.3V)

Hardware/Software Environment:MCU: STM32G030K6T6SDK: MCSDK v5.4.8 (CubeMX v6.3)Current Sensing: Single-Shunt (Rshunt = 0.1Ω, Op-amp Gain = 7.5)Motor: PMSM, Nominal 900 RPM.Observer: STO-PLL, Min Reliability Speed = 350 RPM.The Problem:I am trying to start a motor that is windmilling at 500 RPM in the CCW direction. My application requirement is to run in the CW direction at 900 RPM.Currently, when I call MC_StartMotor1(), the motor slows down slightly but continues to rotate CCW. The State Machine transitions from IDLE -> START, stays in START (Rev-up) for the duration of the phases, and then returns to start-up fault.Normal start from 0 RPM works perfectly.Rev-up Table: Phase 1 is 0 RPM (Alignment) for 2000ms at 90% nominal current. Subsequent phases ramp to +450 RPM.Manual Braking: I have implemented a PWMC_TurnOnLowSides() call for 500ms in the CLEAR state to dissipate CCW energy, followed by PWMC_SwitchOnPWM().Observation: Despite high alignment current, the motor "slips" and ne

Hi ST Community,During my application startup I am facing an issue where TIMx_UP_IRQHandler is constantly triggered while using HAL_Delay(). It seems that the Motor Control SDK is using TIM1 which periodically fires the TIM IRQ handler, interfering with my startup routine.To verify this, I commented out MX_MotorControl_Init() in main.c and my startup routine completed successfully.My startup routine must not be interrupted by the Motor Control tasks. Therefore I need to delay the Motor Control initialization until my startup is complete.Is there an official API to temporarily disable Motor Control Tasks during startup and re-enable them once the application is ready? ( I would like to avoid shifting the MX_MotorControl_Init() function in my startup code) int main(void) { ... /* Initialize all configured peripherals */ ... MX_MotorControl_Init(); MX_IWDG_Init(); MX_SPI2_Init(); /* Initialize interrupts */ MX_NVIC_Init(); // Disable IWDG if core is halted __HAL_DBGMCU

I have created a project in MotorControlWorkbench version 6.4.0 with both no RTOS and FreeRTOS (by clicking the radio button in MotorControlWorkbench) and gotten it to work successfully on my custom hardware based on the EVLServo1 eval kit.  However, because I use he Keil toolchain I would prefer to use RTOS2 RTX5 for my RTOS instead.  I have managed to create the project with MotorControlWorkbench (with no FreeRTOS) and then when I open it in Keil I go into the Manage RunTime Environment and enable the RTOS2 RTX5 RTOS.  This adds a number of files to the project.  I have worked through a number of compilation errors and am now getting one last error:Error: L6200E: Symbol SysTick_Handler multiply defined (by irq_armv7m.o and stm32_mc_common_it.o).I understand this to mean that RTOS2 RTX5 has a SysTick_Handler of it's own and so does the HAL libraries created by MotorControlWorkbench and I need to switch one of them over to use a hardware timer like TIM6 instead.&nbs

Hi there, I want to use the AS5048A SPI encoder with the STM32 Motor Control Work bench SDK to precisely control a 3 phase GL30 KV290 Motor. I noticed STM motor control work bench only supports quadrature encoders and I can apparently use custom code to make an absolute encoder work. Is there any information about how to do this?  

I all,I have a question regarding the EVSPIN32G4 board, specifically concerning the feedback resistors used in the current sensing network (default value: 11 kΩ).I am considering replacing them with 150 kΩ resistors. My main concern is whether this significant change will trigger the Overcurrent Protection (OCP) prematurely or cause stability issues with the internal op-amps.Has anyone experimented with such values, or are there specific hardware limitations I should be aware of?Best regards, Jules

안녕하세요. 저는 개인 개발자 입니다. 이번에 steval ctm051 보드를 구입해서 srm 을 공부하려는 데 소스코드를 제공할 수 있다고 해서 어떻게하면 소스코드를 제공 받을 수 있는지 알려 주시면 감사하겠습니다. Please note that the forum is English-speaking, which is why I have machine-translated your question into English: Hello. I am an individual developer. I recently purchased the steval-ctm051 board and would like to study SRM. I was told that the source code can be provided, so I would appreciate it if you could let me know how I can obtain the source code.

I can use a motor profiler with a custom board, but can I use a motor pilot with the same software? Is it possible to use a motor pilot with a custom board?  

Hello, When using the STSPIN32G4 to drive a three-phase bridge for BLDC control, the MOE pin is automatically set to 0. Reading the internal driver status register of the STSPIN32G4 shows the VDS bit is set to 1. I have already set a sufficiently high reference voltage (2V) on SCREF, but this fault persists, preventing my driver from starting normal operation. Hardware has been inspected with no short circuits found, and the lower arm voltage monitored by the op-amp shows no signs of overcurrent. I've placed a 220uF 35V ceramic capacitor on the DC bus and connected an 18V zener diode, with the bus voltage at 12V. The MOSFET used is AGM12N10AP. The BLDC operates at 12V with a rated current of 1.8A. What solutions are available?   *This post has been translated from Chinese to comply with the ST Community guidelines.

Hello ST team,I am using the EVSPIN32G4 evaluation board with sensorless 6-step control.Hardware Setup:Board: EVSPIN32G4Motor: BLDC motor (24 pole pairs)Control mode: Sensorless 6-step (BEMF zero-cross detection)Current sensing: 1 mΩ shunt + external amplifier (Gain = 7.33)PWM frequency: 60 kHzDC bus voltage: 48 VProblem Description:When observing the three phase voltages (U, V, W) on the oscilloscope, I noticed that three phase voltage occasionally becomes flat or loses switching activity during commutation.This issue becomes much more obvious at high speed operation.At low speed:Waveforms are mostly trapezoidal and continuous.as show.At high speed:The floating phase voltage becomes unstable.The BEMF signal appears distorted.In some sectors, one phase seems to lose signal briefly.Ringing and high-frequency oscillation increase significantly.as show. The higher the electrical frequency, the more severe the signal loss.It seems that the floating phase is being clamped or not properly re

Hi,Recently I have purchased ELSERVO1 board to drive BLDC Motors with 20A rated current. I dont have a ST Flasher, instead, I am using Nucleo g071rb board and removed the jumper pins in the board to flash the external ST controllers.I have connected exact, pins in both the boards like, SWDIO, SWCLK, VDD and GND but, I am not able to flash the firmware saying ""Target no device found, Error in initializing ST-Link device" Reason: No device found on target"What will be the issue in flashing the firmware?? I was able to flash to other boards.I am suspecting that the ELSERVO1 board has dead..please provide the solution.  

Hello,I am planning to use BLDC motors in a robotic manipulator where torque control of the motors will be established. Thus, FOC SDK of STMicroelectronics will be utilized. Since the manipulator will be a parallel one, none of the motors will need to make one full revolution and they will work in low speeds as well. They will be equipped with encoder to measure the rotor position that is critical to FOC. Also, the zero position of the motors will be known prior to the running of the manipulator and so absolute position measurement will be no problem.My question is as follows. Can BLDC motors be used in the above mentioned application utilizing the FOC SDK? As I know, sensorless estimation of rotor position requires the spped to be relatively high. However, HFI (high frquency injection) technique of STM can overcome this issue and can estimate the rotor position at low speeds and even at standstill. Only requirement is for the motor to be an interior PMSM. Then, in case of encoder, the

Hi everyone. Following my Previous post, I have acquired a F446 Nucleo supporting 3shunt topology with the IHM17M1, such that I can perform motor profiling. However, I have run into an issue with the profiler getting stuck at 28%. Details are given below. Any help would be appreciated.[PN]: X-Nucleo IHM17M1, Faulhaber 0620-006B[VERSION]: 6.4.1[TOOL]: MC PROFILER[DETAILS]: Motor Profiler is stuck at 28%. The motor spins up in open loop mode. I have tried multiple speeds and currents within the motor range, and they all seem to work relatively well. However, when using the motor profiler, the motor does successfully spin up (enough current, I assume), but then stops before it reaches the target speeds, and then keeps retrying at a lower and lower acceleration. I have also tried a wide range of speeds from 5000RPM to 50000RPM, and all currents from 0.1-0.3A. I suspect it is not a startup error, but rather a sensing error. Given the size of the motor, and the operating current, I have cons

[PN]: NUCLEO-G431RB with EVLDRIVE102BH and custom motor[VERSION]: Version: 6.4.1 Build: 250722.104358[TOOL]: MC PROFILER[DETAILS]: I am attempting to build a new motor controller that runs sensorless FOC instead of 6-step and my first step was to use the profiler to verify some of the figures on the motor's datasheet. Specifically the friction and inertia values on the datasheet seemed suspect and didn't have the right units for the motor controller workbench. Furthermore I'm assuming the gearbox included on the motor doesn't take these values into consideration. When attempting to run the profiler I seem to get stuck at 28%, which seems to be a common issue and it sounds like the issue is the motor not reaching a stable speed per the forum posts I've already read. From what I can tell it seems like the motor is physically spinning at a stable speed and I don't know why the profiler is struggling to read the speed. I have been banging my head on the wall for weeks now an

Hello, We want to use the STMH723ZG with the Motor Control SDK. To do this I cannot find the .json file support for the board in the motor control workbench. Could I use another .json file from one of the fully-supported boards like the H745? Also, we are using custom power electronics + motor setup so to my knowledge our board has sensors it outputs to the stm + it takes a pwm 3-phase input from the stm to spin the motors. What all info do I need and what process do I follow to get a project built for this setup with the motor control SDK.
