STM32 MCUs Motor control

Hello everyone,Based on the screenshots attached, I couldn't understand the formula obtained for the OCP feature of this inverter board.3 phase currents are read through the shunt resistors, got offset, and amplified by the op-amp ICs. So far so good!But PC1, PC2, and PC3 are tied together using 3 one kilo ohm resistors, then the common node is fed to the comparator pin of the MCU to do the OCP task.I am wondering how the Equation 2 is obtained for implementing over current protection, and why it is like this. Why is the G.Rs.Ioc term divided by 3? If you could guide me, it'd be awesome, thanks. 

Hello Everybody, MCSDK:6.3.0 CubeMX: 6.3.0 Workbench : 6.3.0 Motor Pilot : 1.2.9 Power Board : IHM08M1(Rshunt=0.01Ω) Control Board : NUCLEO-G431RB Motor : BLDC 26w 24v/8 pole pairs / rpm=4k / rated current=1.8A/hall sensor   I would like to ask, in SPEED MODE under SMO + PLL, which API can be used to limit the Iq current? For example, if the rated motor current is 2A and the peak current is 6A,I want to limit the motor's current to not exceed 1.8A during normal operation. Which API or parameter should I use to enforce this current limit?Or is there no callable API, and I need to write my own condition checks?But since I am in SPEED MODE, is it still possible to impose a current limit? Thank you in advance to any expert who replies to my question  

[VERSION]: MCWB v6.3.2[TOOL]: STM32CubeMX v6.13.0, STM32CubeIDE v1.11.5[BOARD]: STEVAL-PTOOL1V1[PROJECT]: STEVAL-PTOOL1V1_6S_SLI managed to get this board working with a small BLDC motor but after some time the motor stops and I'm not sure why.  Sometimes it runs for several minutes, and other times only a few seconds.I would like to use Motor Pilot to visualize what's going on in the drive and hopefully find the reason for the shutdown.  I've been looking through the code also and trying to adjust parameters and retesting, but this is just a guessing game.  I was able to connect to the serial port on the PTOOL1V1 board and the Motor Pilot app connects to the board but it seems it's not communicating correctly as it's not able to do or show anything more.  Here are a couple of screenshots of the Motor Pilot application.

I am working on a system that the on/off button only switches the high-voltage power source.  The processor and IPM continue to run.  First problem we had was that you cannot clear faults or execute the MC_StopMotor1() function because the system is still running and generating under voltage faults.  We worked around this by not doing anything until the power was turned back on.The scary problem is that, when the power comes back, the system spastically jumps in one direction or the other.  My assumption is that it is trying to complete its last movement from before the power was turned off.  I have tried numerous function calls and we have even dug into the bottom layers of the library to try to figure out which fields to clear.  I was really hoping that there was a simple reset function, but I sure don't see it.  Right now, I'm looking at saving some state info in NVD and issuing a call to  NVIC_SystemReset().  Did I mi

 Hey, I have troubles with my B-G431.Two problems with the B-G431:MotorProfiler 5.4.8: Measurement of Profile is taking too long, no matter how I change the values. MotorProfiler 6.3.2: Can't connect to the Board. It can't even open the port. Does anyone know what the correct BAUD Rate should be?What I already tried:- Reinstalling MC_SDK in Documents- Flash the file: ...\Utilities\PC_Software\STMotorPilot\STM32CubeProgrammer\Fw with CubeProgrammer, doesn't help, it still doesn't recognize the board.Also opening the board in CubeProgrammer with the UART Connection is not possible, only the ST-Link worksThanks

 Hi, Partner,Here's the problem I've encountered and how to solve it,I'm working with the following setup:System: win 10 22H2, RAM 4G, i3-6100 Hardware: Nucleo F072 + STEVAL - IPM03B +SPMSM 0.8HP + Hall sensorSoftware: SDK6.3.2, Cube Max 6.13, Cube IDE 1.17 Version info:MC Workbench: 6.3.2WB_to_Mx : 6.2.3. template-24-04-17STM32CubeMX: 6.13.0MC Firmware Library: 6.3.2-FullGeneration options:Target Toolchain : ST STM32CubeIDETarget Driver : LL - Low LevelTarget STM32 FW : Latest  

I have a custom design using SDK 6.3.2 that was started by modifying the board files from NUCLEO-L476RG and X-NUCLEO-IHM07M1. When the custom board was designed, the Phase order was changed from default (U/W flipped):TIM1_CH3/3N, ADC1_IN1 Current - Phase UTIM1_CH2/2N, ADC1_IN2 Current - Phase VTIM1_CH1/1N, ADC1_IN3 Current - Phase WThe ADCs for current seem to remap just fine, but it looks like PWMs are expecting to be in order: U,V,W even though the SDK lets you map the boards however you want. I believe this is configured in the code here which doesn't change when I generate the project regardless if I select 1/2/3 or 3/2/1 in the configuration. Nowhere does PhA get swapped for PhC as far as I can tell. Also of note the SDK 5.4.8 sets a fixed order for PWM channels where as 6.3.2 lets you specify whatever you want in the GUI without checks. Is this perhaps a level of configuration offered by the new SDK that isn't supported by the libraries, but isn't checked for valid

On the wiki page:https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor It says:""This article applies to the 5.Y.* versions series of the X-CUBE-MCSDK. ACIM motors are not supported in older versions of the X-CUBE-MCSDK (v5.4.* and before). They are not supported yet in X-CUBE-MCSDK versions 6.*." However, the latest v5 version I can download is 5.4.8. So, it appears that I would need to use version 6 to compile the examples, while full support comes later?       

Hi, I'm developing a board to control motors using FOC. For this, I will use the MC workbench tool to generate the code. However, when I describe the hardware in the shunt resistors section, there is no "in-line" option, only the low-side option, but my board only has them in-line and I can no longer modify it. What can I do in the code to be able to use the shunt resistors in this way?

Hello community Please help me, i am facing issue related to injected ADC on PWM timerMCU : stm32f103, working on motor control for BLDC motorExcepted : When motor is running that means it generated PWM, at that time Injected ADC value must be shore.This is my ioc setting for PWM timer that is timer this is setting for injected ADC ioc filecode to state   HAL_ADCEx_Calibration_Start(&hadc1); HAL_ADC_Start_DMA(&hadc1, (uint32_t*) Measured.rawADCValues, 4); HAL_ADCEx_InjectedStart_IT(&hadc1);void HAL_ADCEx_InjectedConvCpltCallback(ADC_HandleTypeDef* hadc){ Measured.phaseADCValues[0]=HAL_ADCEx_InjectedGetValue(hadc, ADC_INJECTED_RANK_1); }

Hi everyone,I have problem about ST Motor Control Workbench.I can ' t generate project.I tried so many things(I installed and unistalled different versions , I changed OS language etc.) but I couldn't do it .Please help.

Hi, I'm using STSPIN32F0A to control BLDC.I have a question regarding the operation of the OC protection.we expected that the two corresponding low side MOSFETs would turn on when OC COMP pin detects the over current.However during actual operation, we observed that the two MOSFETs turn off for 1us which is equivalent to the dead time we set before turning on two low side MOSFETs.Can we remove this 1us period turning off both low side MOSFETs?We currently set OC_SEL(PA11) to 1.

I have STEVAL-CTM012V1 evaluation board for 250 W. I have followed all the procedure which are mention in the manual where I first load the firmware file stsw-ctm11 in motor control work bench then click on generate code then goes into cubemx then generate code and goes into STM32CubeIDE and project is created. So my question is that the generated project is enough to run motor means we just need to upload the code into the board and it will start motor right? 

Hi everyone, I have purchased a STMicroelectronics STEVAL-CTM015V1 drive. How can I find its default firmware code (Current chopping control for switched reluctance motor) in  STM32CubeIDE workspace? I would like to get connected with the people already working with this product. Thank you, Regards 

Hello,We've designed a STSPIN32F0251-based motor driver board, but when running the 6-step firmware algorithm, the motor aligns and then vibrates with a high-pitched sound. When we check the state-machine, we can see it reaches the RUN state after executing ALIGNMENT.We probed the inverter output phases on both our custom board and the EVSPIN32F02Q1S1 evaluation board, observing significant differences in pulse width and voltage levels, despite using:The same user codeThe same PSUThe same motor & encoderScope CapturesCustom Board:Channel 1 = OUTAChannel 2 = OUTBChannel 3 = OUTCEVSPIN32F02Q1S1:Channel 1 = OUTAChannel 2 = OUTBChannel 3 = OUTCChannel 4 = Current Sense Amplifier OutputBoard ModificationsTo match the EVAL board, we made the following PCB modifications:RES5 pin grounded via flywire.V+ and V- on U2 were corrected by lifting the pins and flywiring to the correct nets.There are more differences between the two boards, I detailed them here below and attached the schematic PD

Hello,Setup: G431 MCU, custom board with three phase voltage channels, HSO. Default Workbench generated project measures three currents, three voltages, Vbus and Temperature.We need to measure two additional analog signals, how to make it without reworking most of oversampling and ADC relates defines and structures?Simple modification @ STM32CubeIDE will not work because DMA structures are deep in motor control code.Thank you in advance!Sergey 

I wasn't able to find the STM32 MC SDK reference manual. Can anyone share a link ? 

How can I change the rev-up and stop ramps programatically ?I can change the rev-up ramp through motor pilot but I have to do it everytime it connects.I want to control that through the program.I'm using code generated from the MC WB / MC MX / MX IDE chain.Board is a B-G431B-ESC1Thank you

I am using B-G431B-ESC1 board and GBM2804H-100T Brushless Gimbal Motor, properly generated the code. But upon receiving PWM signal, Motor is behaving:Motor spins then zero spins then zero soon then spins.Although Motor is working with other controllers fine and fresh B-G431B-ESC board also behaving same. Kindly explain. 

Hi, my name is Luis.I'm using MC SDK 6.3.2 with a custom board for a single shunt driver in 6-step mode.I defined the OCP mode to  use internal comparator and enabled over current protection in MC project configuration.The generated ioc file configures the DAC3 OUT1, COMP and enables, for TIM1, BRK from CMP1 source with polarity high. What I have not seen anywhere is the DAC value corresponding to the current limit I have configured.I've tried to trigger overcurrent protection with a motor I'm driving correctly by brakeing it, but I'm unable to trigger protection even if the current is way above the configured threshold.It looks like SDK doesn't really handle the configuration of the DAC and so overcurrent protection is just not implemented.On a different board with a 3-shunt resistor I have seen the .DAC_OCP_ASelection defined in R3_ParamsM1 inside mc_parameters.c and the function R3_SetAOReferenceVoltage called inside r3_g4xx_pwm_curr_fdbk.c and it seems to work o

When compiling a test app for the B-G431B-ESC1 board, I generated code using the MC Workbench and cube MX for a 6-step control of a BLDC.If while in the Workbench, I choose to enable the "Electronic Speed Control" option, I get the error below when compiling inside the ST IDE: C:/Users/pjreb/.st_workbench/projects/test_4_6s/MCSDK_v6.3.2-Full/MotorControl/MCSDK/MCLib/Any/Src/esc.c:293: multiple definition of `TIM2_IRQHandler'; ./Application/User/stm32g4xx_mc_it.o:C:/Users/pjreb/.st_workbench/projects/test_4_6s/Src/stm32g4xx_mc_it.c:103: first defined here How can I fix this? Thanks

I am using GBM1008H-150T PMSM motor. Cannot get motor parameters using "Start profile". Motor is noisy and rotates jerkily. I am applying 24V. Specification says the motor has 14 pole pairs and 7 KV.
