STM32 MCUs Motor control

Hi ST CommunityI am having a MotorControl setup with the B-G431B-ESC1 board. The default project generated with MotorControl Workbench uses the OPAMP1, 2 and 3 and their outputs are set to pin A2, A6 and B1. These output pins are then fed to the ADC: ADC1_IN3 (A2), ADC2_IN3 (A6) and ADC1_IN12 (B1).In my setup, I need to use the pins A2, A6 and B1 for other GPIO purposes (already used all the other pins). I am having a hard find figuring out whether it is possible to route the OPAMP outputs internally to the corresponding ADC without wasting uC pins. Does anyone know if this is possible? Edit: In the document: AN5310 Guideline for using analog features of STM32G4 Series versus STM32F3 Series devices, table 10 shows the overview of "Internal OPAMP to ADC connection without external pin occupancy". So it must indeed be possible. I must figure out how to set this up in the CubeMX project.

Hello, I am new in STM32Cube. I try some test with PWM timer 4. It  works. I see the signal on oscilloscope. But why is not in clock configuration  highlighted the timer clock and I can not also change the clock source.Best regards.  

Hi. I'm using the STM32F407VE6 Microcontroller board. Is it possible to use a single timer to generate PWM from channel 3 and read the encoder values from channel1 & 2 of the same timer? When I tried using 2 different timers, one for PWM and the other for the encoder it worked fine. If it's impossible to use the same timer for both operations, why are channels 3 and 4 available for PWM generation?

Good day,we are currently integrating the XCUBE-Dpow library but are running into multiple issues due to the lack of code documentation of the library.- We are not using HTIM Channel-C but -D. After changing multiple entries in the template files of the library, the output works, but High/Low side are inverted.-> Is it possible to invert the dutycycle (High connected to TD2, Low to TD1) or invert the output configuration?We have tried but did not succeed.-> none of the protection functions are integrated, it is unclear if the K value is needed and also, in the documentation the REF value is not inserted into the ADC, as well Channel C is hardcoded.Also, in AN5496, it is missing that for the ramp to work the REF value in the Dpow library has to be set to:(uint16_t)(vLoop.m_Out) - is this correct?Is there any documentation I am missing? Many things are not intercompatible, and there also were some errors to fix after migrating to CubeFW 1.6.0It would also be nice to know which of t

Hello, I am very new for ST MCU,I have made may own evspin32f0602s1 board , after many trial and errors also after gone through documentation  ,I got  PWM output. but problem is that I  getting it at Reserved pins of MCU (TP1,TP2,TP3 in evolution board) .I have spend so much time but not getting any solution ,Please guide 

Hello, I am using MCSDK_v6.3.1 and encountered a problem when changing TIM1 PWM pins:I cloned B-G431B-ESC1 Devkit Inverter.I changed High Side TIM1 PWM pinsUH: PA8 -> PC2VH: PA9 -> PC1WH: PA10 -> PC0When I now want to create a project with the modified inverter, I get this error:  Error It is not possible to create a motor control project with the FOC algorithm using the selected hardware. No proper path for motor control signals was found for the following mandatory features: - Phase Voltage Generation For more details, please, look at the following log file in your home directory: .st_workbench/connectAlgo.log  I opened connectAlgo.log, but do not see an error.Is this a bug?Thanks 

Hi Guys,I am new to motor control, and I have chosen STs controller board NUCLEO-G431RB and inverter board X-NUCLEO-IHM08M1 for BLDC motor control. please give me an insight on what all software tools you provide for easy development. Is there any tool that can be used to monitor Realtime motor parameters?

I need to implement runtime current limitation.Another thread says to use "PID_SetUpperOutputLimit" on the PidSpeedHandle for that to change the values originally defined by IQMAX, which makes sense.However, I also found NOMINAL_CURRENT used for MaxPositiveTorque and MinNegativeTorque in SpeednTorqCtrl, which has been set by the MCWB tool to the same value as IQMAX.What are these values used for? Do I have to change them as well? There doesn't seem to be a function for that.NOMINAL_CURRENT is not mentioned in the SDK documentation and a comment in pmsm_motor_parameters.h only says it is used when  Id = 0 "to saturate the output of the PID for speed regulation" (so it does the same than changing IQMAX?), even though there's no Id to set anywhere.

MCSDK v6.3.0Problem: MCWB generated code with quadrature encoder does not spin motor properlySTWB6 file is attached.  I had to copy and paste the contents into a .txt file to upload it Here are links to videos with quadrature direction reversed and not reversed.  With the quadrature reversed I press the SW1 button and the motion seems to be somewhat smooth for the motion the motor makes.  With the quadrature signals NOT reversed the motor alternates back and forth violently and produces vibrations enough to move the motor test stand for ~5sec then cuts out and will not restart. The motor commutates smoothly in sensorless FOC mode using SW1 button startup.  Then I change the Speed Sensing Config to use the encoder signals and the motor behaves as described above.  The encoder has 4096 slots which is what I'm using for pulses per revolution.  I also tried 4*4096 (16,384) ppr but that resulted in a hard fault of the firmware immediately on star

I am trying to find the correct PI controllers parameters for my E-Scooter application. Initially, I determined the parameters of the motor through the Motor Profiler, but now I wondered what inertia should be specified. The inertia of the engine idle is quite small, but when the E-Scooter moves with a passenger, the inertia of such a system is many times greater. Since the calculation of PI controllers depends on this, I would like to better understand how I should calculate it. I am also interested in the cut-off frequency parameter, since I have a low-speed application of only 500-600 rpm max, which frequency should I set if I do not need high-frequency pulsations that may arise during control.

Looking to support an old project using an induction motor control dated 5-29-08. Over the years, unfortunately the library was lost and only have the project source files. Maybe an old motor control kit might have this library set. It included Space Vector PWM and current shunt functions. The header file was stm32f10x_svpwm_ics.h if that helps.Normally I would start over, but the project has a very short deadline. The project was built with IAR and have that license. Access to this library or development kit software would be appreciated. 

Hi,Starting from this development board, would like to know if I can add easily encoder (which one) and if there are example project for a servo driver, I mean code to control speed and position of the gimbal motor.Thanks in advance

I am using MotorControl Workbench (6.2.0) to setup BLDC position control, where Quadrature Encoder is enabled with PPR = 4096. After generating the project, TIM2 is automatically set as Encoder Mode as follows:Now I want to double the resolution with PPR = 8192. Usually this can be done by setting Encoder Mode to be one channel and choosing polarity of that channel to be both rising and falling edges. However, in STM32CubeMX, it is not allowed to set polarity of channels to be both edges. My question is: How to double the resolution of quadratic encoder if MotorControl middleware is used?p.s. I also set the polarity of channel 2 to be Rising Edge (the same as channel 1), but the BLDC control doesn't work anymore. Seems like only the default setting (as shown in the figure above) works. Any special reasons behind? 

Hi, I recently bought a STEVAL-SPIN3204 and now i want to connect it with my PC, i connected it with the USB cable, selected an example project for this device and clicked on connect, but there comes always the error message, connection failed. What did I do wrong or have i forgotten? Here you can see a picture of the interface:I also checked the baudrate and everything. 

Hi All,I am a newbie in motor control. I am having a X-NUCLEO-IHM08M1 board with me I came to know that it supports both sensored as well as sensorless motors, but could'nt find a sensord motor that is compatible with the board but found one sensor less motor named BR-2804. Can anyone suggest a motor that comes with hall effect sensor which is compatible with the board. If motor does not come with any sensor in it, can we add external sensors to it, If yes can anyone suggest a sensor too.With regards,Tashi George

While I run my firmware after motor profile, over current issue is showing even though when current is not drawn. So kindly suggest a solution accordingly please.

Hi,I am having weird trouble in printing serial prints over UART to my pc using the nucleo motor control kit F302R8 based MCU. The motor works fine but when I try to print logs over UART the thing enters into TSK hardware fault, although I could print things fine when I open a plain project for the board. please help me out urgently as this needs to go in production ASAP!

Dear Sir, I am developing a motor control system with STM32H563, and I need to measure the 3 phase current by ADC.I would like to configure the ADC1 with injected mode and transfer the ADC data via GPDMA.I can't find the information from reference manual and no appropriated API in HAL Liibrary. The DMA is only availabe with regular mode.  Does anyone how to use injected mode with GPDMA? Is it feasible?  Best Regards, 

Hey all,I'm using the STM32F423ZHT6 for a Smart Lock with 2 limit switches for lock/unlock. The problem is, the motor stays on all the time, so it’s using a lot of power. Any tips on (https://faisalmoversonline.pk/) how to reduce this? I want the motor to run only when needed.

I'm using STM32F423ZHT6 MCU board for Smart Lock operation. Here, I'm using 2 limit switches.Based on the Limit switches door is lock and unlock. But, the motor is always on state so it consume more power. How to reduce my power consumption.Please anyone help me.

I am having X-NUCLEO-IHM08M1 board. From the documentation, I came to know that it supports both FOC algorithm as well as 6- step algorithm. I came to understand FOC algorithm is used for torque control. Correct me if I am wrong. But I didn't get any info regarding does it can be used in both sensored as well as Sensor less configuration. Also, can anyone give me an idea on what is the significance of 6 step algorithm and what is its application.Thank you.
