My sensors polarity active low at my custom board I'm using a inverting schimitt trigger how can i change hall polarity at software 

Hi team,I have rotary encoder (Model - OVW2 -2048-2MC). Its resolution is 2048P/R. I get the encoder count via uart, but I have a problem, when encoder rotate continuously it does not give the data via uart, move slowly the encoder it update the value, I dont know why this happen during the data transfer. the second one is, how I will convert the count value into rpm, what is the procedure to convert the encoder count into rpm. for your reference I attached my code below. if any logical error, parameter setting error and peripheral error in the code mention all the errors also, and gave procedure for rpm calculation.thank you regards Ramachandran S/* USER CODE BEGIN Header */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "stdio.h" #include "string.h" #include "stm32f4xx_ha

**EDIT: I misunderstood the implementation of the open loop mode, as I thought it was performing open loop SVPWM at a particular modulation index. After reviewing the open loop documentation within the motor control docs I now understand that this is not the case and will attempt to use it properly... please feel free to delete this post** Motor control workbench version : 6.3.0Motor pilot version: 1.2.9Hello!I would like to perform an open loop modulation test. After configuring the project to allow open loop and selecting OPEN_LOOP_VOLTAGE mode within the profiler, I am unable to alter the voltage reference within the advanced pane. As soon as I alter the value, it is immediately reset back to 0. If I run the open loop modulation with a voltage ref of 0 then the high side U FET sweeps from 0% duty cycle to 100% which subsequently trips the power supply and produces an undervoltage fault. Are you able to assist me on setting an appropriate voltage/modulation index for open loop c

Hello,I have a custom inverter board which is designed for high power applications 100A+. I have individually tested the hardware functionality of the inverter and all seems to be well. However, when I run the motor profiler, a huge amount of current is drawn within the first two seconds (20A +) which hits the current limit of the bench supply I am using. This subsequently causes an undervoltage fault. I have set the correct pole pairs and RPM, and have tried setting the max current to a range of values between 1A and 10A but I always get the same result.No overcurrent fault is ever detected, despite this being the root cause of the undervoltage faultWould this typically indicate an incorrect configuration of the current sense setup, and are there any other parameters that I should be aware of which can result in such behaviour? I am using a 1mOhm shunt with an external op amp that has a gain of 16, which I believe is reflected in my MCSDK project

Hi, I am using ST Motor Pilot Tool (profiler) V1.2.9.With the B-G431-ESC1 plate and the A2212/13T motor (technical sheet attached).I can't get the motor above 5200 RPM. Please note that to get to 5200 rpm I had to increase the overvoltage to 80% because otherwise I would get an overvoltage error.How can I get the engine to reach 10Krpm?Is it normal to increase the over voltage so much?Thank you very much for your time and support.

Hello everyone,I am running into a problem with the STSPIN3202 evaluationboard. I cant get my BLDC motor A2212 930KV 15T with sinusoidel BEMF to spin.I have tried 6 step sensorless and FOC sensorless. In case of 6 step the motor keeps buzzing stationary so it is wat i think a startup problem. With FOC it just gives beep and nothing more(I didnt forget to change the jumpers according to https://www.st.com/resource/en/user_manual/um2278-getting-started-with-the-stevalspin3202-evaluation-board-advanced-bldc-controller-with-embedded-stm32-mcu-stmicroelectronics.pdf ).For both methods I took some example code from the MC workbench and changed some motorparameters and the Vbus voltage.V-bus voltage is 11VFor the Motorparameters I couldnt find a datasheet so I had to determine them.The pole pairs parameter is determined by spinning the motor with my hand. Full rotation counted (12 steps so 6 pairs).The board is powered with 11V.The Rs and Ls are measured with a multimeter and a LCR meter

HelloAfter trying to run a EVSPIN32F06Q2S1 in FOC Mode, which is failing at the moment (i'm working on it), i tryed to run on 6 step mode and see if this works.So i configured the board via mcwb 6.3.0, made the hardware chances which the mcwb told me to do, uploaded it to mcu and tried to run via motor pilot.At the first tries, the motor started vibrating and wanted to spin, but it failed after a few seconds. Now i face the problem, that IMMEDIATLY when I press "Start" in Motor Pilot, an overcurrent fault occurs. I tryed to measure the current with oscilloscope, but nothing is seeable/no current is flowing.Can anyone help me with this problem? do i have a wrong current ramp or something like that?I tryed so much, but nothings helps..Thank you! 

Hey all, i believe i've found a mistake on the stspin32f0601 datasheet.  https://www.st.com/en/motor-drivers/stspin32f0601.html Page 12, RON_OD, Units are in Watts instead of Ohm, I believe this is supposed to be the value of RON_OD.   Thank you  

Hello, I am using the MotorControl Workbench_6.3.0 tool.and it gives me an error when generating the project.In the end it tells me completed with errors.What is happening wrong?Thank you very much for your time. 

Hello, I have following problem:I generated a project using MC Workbench (6.3) and everything works with Motor Pilot (1.2.9). For debugging I would like to have a serial output over the same USART as the motor pilot. For start just print "Hello World!" every second inside the main loop.printf: does not workHAL_UART_Transmit: works sometime for 1-2 messagesHAL_UART_Transmit_DMA: does not work.Is  there a simple way to send custom (maybe through MCP)?Best regards 

I purchased EVLAKIT-ROBOT-1 and am trying to run it.I request information for operation.An error occurs when building the example code.I wonder if the problem is caused by the software tool version. If so what version of software should I run it with?1. STM32CubeIDE version?2. MCWB version?

Hi,I am new to STM32 and am using a STM32L452RET6 and need to have two PWM signals so that they can be configured via software to sometimes work in perfect sync (i.e. as if they are the same pin output) and some other times to work 180 out of sync (i.e. when one is low the other is high). I am currently using PA0 to generate the first PWM. Which pins can I use to setup the second PWM so it works as mentioned above? If for some reason it is preferred to use another pair of pins, can you please suggest which ones). Thank you :smiling_face_with_smiling_eyes:

So i've been having an issue with the Powerstep01 driver to run some stepper motors. In my application i'm running 4 stepper motors with a wide speed range (up to 850 RPM or 2980 steps/s). These motors are STP-MTRH-24079D which have parameters (Iph = 6.3A, Rph = 0.3, Lph = 2.1 mH). Now, i'm primarily using the "run" command to move these, and that works well until they cross a certain speed. once this threshold is crossed, the phase current waveform goes wild and the motors slip. I am using the full step mode at about 1100 Steps/s, i'm not sure the relevance. These drivers are being supplied a raw 48V DC from a LiFePo4 Battery pack, using internal clock set to 8 MHz. I've checked the VS levels while running and some voltage is lost at speed which makes sense. But, this behavior seems to be a driver setting of some sort. Any ideas?  

Hello,we have STSPIN32F0601 based custom designed board for PMSM motor Controller. we have generated FOC code using  MC workbench and it works ok.Now we want to use ACIM motor in this Hardware (with Little change or No change in Hardware). we are unable to generate code from MC workbench for ACIM using STSPIN32F0601 MCU. we have used single shunt current sensing.please guide me that how can I generate code for ACIM ( for STSPIN32F0601 MCU and V/f Control Mode) using motor control workbench.please share if any example code available for ACIM and STSPIN32F0601 MCU.Thanks.

 Hello everyone,I am currently working on a project involving an Evspin32G4-Dual Board, equipped with two brushless motors (Hover Board motors 36V-10A-500 rpm-Hall Sensors).I have completed profiling the motors and their hall sensors using MC Workbench 6.2.1. Afterward, I generated the project using MC Workbench 6.3.0.However, when I tried to run the motors, they wouldn’t spin and started stalling. To address this, I loaded the FOC UI in Motor Control and began adjusting the PID values for the flux regulator. I observed various behaviors as I made changes.From this, I concluded that I need to perform a tuning procedure for both the current regulator and the speed regulator.Is there a way to perform this tuning in Motor Pilot 6.3.0 or 6.2.1?My goal is to achieve high torque to lift mass in Speed Control Mode.Thank you.

I use 2048 PPR encoder for speed control. It work well.But if I change the motor mode from speed to position control,something goes wrong.If we select Z signal for shaft zero alignment,the code after reset belowMC_StartMotor1();while (MC_GetAlignmentStatusMotor1() !=TC_ALIGNMENT_COMPLETED);it will get the motor speed to maxAnyone knows the reason why.Thanks

how to upload the data collected by Motor Pilot to the company's server

Hi,I'm working on a motor control project using STM32 microcontrollers and plan to use the Motor Control Software Development Kit (MCSDK).I noticed that the STM32U series isn't listed in the wiki for MCSDK compatibility, which currently includes the following series: STM32G0xx, STM32F303, STM32F302, STM32F301, STM32G431, STM32G474, STM32F4xx, STM32F7xx, and STM32H7xx.Is the STM32U series compatible with MCSDK? If anyone has information or experience with this, your help would be greatly appreciated. Any resources or example codes would also be very helpful.Thank you!

Hello there,I am currently working on a project considering the B G431B ESC1 and a BLDC motor.My goal is to control the motor through a external PWM Signal from a nucleo board.So far I could only control the BLDC motor through the MC Profiler and only in 6Step mode.After some research I found out that in order to control the BLDC motor with an external signal the ESC setting must be activated in the "Stage Configuration".I did that and generated the code for the B G431B ESC1, however I recieve the following error message found in error.txt.Some variable seems not be declared.Any tips on how to solve this issue?Thanks in advanceBatu 

Hello,Thank you for reading.I am a student working on a project to drive BLDC and PMSM motors using the NUCLEO-F401RE development board and the X-NUCLEO-IHM17M1 motor driver expansion board.I have successfully generated the project files in CubeIDE using the MC Workbench SDK and CubeMX. I have also read through the code and have a good understanding of how the TASK management flow is implemented.However, my main question is about the principle of driving BLDC or PMSM motors using this motor driver. I want to understand the mathematical model and the driving principles in order to modify and design new functionalities through coding in the IDE.Despite reading the hardware datasheet and SDK usage guide, I have not found sufficient information to help me with designing in the IDE.I would greatly appreciate it if you could provide links to any official documentation, video tutorials, or other reference materials that could assist me.Thank you very much.
