STM32 MCUs Motor control

Posted on November 06, 2017 at 19:19I can select this configuration in STMCWB and generate all files, but the compiler complains in line 424 of MCTasks.c  oCurrSensor[M1] = (CPWMC)IF3XX_NewObject(&PWMnCurrFdbkParamsM1, &ICS_DDParamsM1);Error[Pe167]: argument of type 'struct <unnamed> const *' is incompatible with parameter of type 'pICS_F30XParams_t' C:\...\MCTasks.c 423 I checked, 'ICS_DDParamsM1' is of type 'ICS_DDParams_t', whereas the function expects a pointer to a parameter of type 'ICS_F30XParams_t'.

Posted on February 27, 2018 at 10:19In UM1052 it says that ICS current sensing is only available for F103 HD, F2xx, F4xx. However the class ICS_F30X_PWMnCurrFdbk is part of the MC Library. Is this class with it's functionality a work in progress? It does not compile as reported here:https://community.st.com/message/174361-foc43-dual-motor-with-ics-sensors-and-stm32f3-does-not-compile It seems that development of this class is started but not finished. But why include unfinished non-working SW in the lib? What is going on here?I wish to run F303 single motor control with a 2-shunt inline current sense topology.  #sw #ics #f303re

Posted on December 11, 2014 at 16:05Hi, I am trying to use the FOC4.0 library with dual rotor angle feedback, namely hall plus encoder. I can set this configuration via the GUI (I have to manually edit the generated header files because of a bug in the tool, creating a wrong #define), but when compiling this setting, I end up with compiler errors. Digging deeper into the code, it seems that the library is not prepared for this configuration. For dual sensor mode, I understand that I will need an interrupt service handler for the encoder, and a second one for the hall sensor. Unfortunately the module containing these handlers just creates one handler that can be configured for the one, or the other, but does not handle both of them. So I have the question, is this issue known, and perhaps already solved? If not, I would need some help suggesting the necessary additions and modifications. Kind Reg

Posted on February 06, 2015 at 19:36hello every body,i generated header files using MC workbench, and then copy them into sys_drive_param folder. then when i open workspace in project folder. it contains only STM32F30x_userpoeject, but according to the um1054 mannual , there should also be STM32F30x_MCLibrary,  can i compile the code without adding STM32F30x_MCLibrary, and batch build is necessary for web distribution lib.? please guide me..thanks #stm32f100x-foc-liv-v4-error

Posted on March 11, 2015 at 22:52Hello,Does the PMSM FOC library support single motor drive using OPAMP3/4 and ADC3/4 on STM32F303RB?I did my own HW like that but it seems that the library still tries to check some flags of ADC1 even if none of the signals are connected to ADC1 nor 2.PMSM manual says: the pair OPAMP3/OPAMP4 can be used additionally in a project based on STM32F303.What does this ''additionally'' mean? That it's the second option or that it supports second motor? #pmsm-single-drive-adc34 #opamp3\4 #foc4.1 #stm32f303

Posted on December 29, 2011 at 03:28[Resolved]: When the Over-current protection disabling network check box is clicked on the (Power Stage - Over Current Protection) page the port and pin values can then be changed. ----------------------------------------------------------------------------------------------- I am unable to change the port and pin for the Over current Protection Disable in Motor control workbench.  All the enables for this are set properly.  I can edit the output files and change the pin but not in the MCWB application.  Is this a bug or am I missing something?  Photo included shows option greyed out.  

Posted on March 31, 2014 at 21:32I am receiving this compiler error in SystemNDrivePrarms.h on lines 8182, 8216, and 8250 when compiling MCTasks.c.  (MC version: 3.4.1, IDE: IAR EW for ARM 7.10)  ID_DEMAG,        /*!< Demagnetization current in s16A:                          Current(Amp) = [Current(s16A) * Vdd micro]/                                 [65536 * Rshunt * Aop] */ The demagnetisation value I input to MCWB is 5.1Ampere.  Did I do something wrong?  To work-around, will the algorithm tolerate a maximum representable value that has not truncated? #hj #i

We have developed our own MC board, based on STM32F303RE (like the STM32F303 Nucleo-64 board). The pinout is slightly different. In the MCWB I can set the pinning correctly for the 3 phase but in what way can I set the correct ADC input to the B-EMF signals? I urgently need an answer, any help is welcome!

We have developed our own MC board, based on STM32F303 Nucleo-64 with some different pinout. We do not have integrated ST-LINK like the Nucleo board of course, just a JTAG connector. Can we use our custom board in combination with the MC monitor? When I press now the "connect" button, it does not connect. The code was generated correctly by MCWB, some additions made with STM32CubeMX, code generated for Keil v5 and flashed into the custom board. The software functions in our custom board, serial connection is available and we tested it with a simple terminal program.

I have the Shinano motor running correctly with the NUCLEO-F303RE board and the X-NUCLEO-IHM08M1. I'm trying now to get it working with our custom board. Unfortunately my hardware colleagues have used the NCP5304 bridge driver instead of the L6398 driver. The NCP5304 has a smitt-trigger inverter on both IN-Hi and IN-Lo inputs where the L6398 has only an inverter at the IN-Lo (LIN) input. The PWM signal to the bridge driver shows now identical signals at both inputs, which is correct for the L6398 driver. But for the NCP5304 I need one PWM signal to be inverted. Can this be done easily? I tried to do that with the MCWB by changing the "Power Stage - Driving Signals Polarity" but this seems not to be working.

Hi, I am using the NUCLEO-F302R8 and X-NUCLEO-IHM08M1 to drive a BLDC motor with hall sensors (placed 120 degrees apart) and incremental encoders (1024 per revolution). I have noticed that MCWB allows the option to use both the sensors, but when I go to generate the project it complains about he pin being the same which I have solved simply by using different pins for the encoders. Now the issue is that they both use the same timer (TIM2) and there is no option that allows to use different timer for either of the sensors. I am aiming to control the motor at very low speeds, this is not possible by using hall sensors only as the motor stops with a feedback error at speeds lower than 1000 RPM. If I try using only the incremental encoders the motor doesn't spin at all, the motor draws a significant amount of current but the rotor is just locked. Is there anyone who had the same or similar problem and possible had found a solution to it?I'd appr

im very new with EVALKIT-ROBOT-1. I loaded the EVALKIT-ROBOT-1.stmx V5.4.3 File which was delivered with the Kit into the MCWB 5.4.3. Because in can’t find a Board named STEVAL-SPIN3201 i can’t use the MotorProfiler.When i load the EVALKIT-ROBOT-1.stmx V5.4.3 into the MCWB 5.4.3. and open the Monitor i can’t Connect to the Device. I tried all Baudrates and used the Com45 who i got new, when my RS485-Adapter was connected on USB.I tried that first with the original Firmware delivered on the EVALKIT-ROBOT-1. I generated a new *.ioc File with the settings STM32CubeMX 5.6.1 and the Toolchain ST STM32CubeIDE and selected the STM32 FW V1.11.0 Firmware-Package (Recommended). I selected the LL-Driver-Type.I compiled the Project Error-Free and programmed the resulting EVALKIT-ROBOT-1.elf over the STMcubeProgrammer with StLink V3 to the EVALKIT. Verify was OK.But with this firmware, there was also no Connection in MCWB-Monitor possible.

Posted on August 09, 2017 at 13:44Hi. I am using MCWB with FOC 4.3. with STSPIN32F0 eval board. I am trying to switch on the bus voltage sensing. When I set it in the WB, compile and upload, it always randomly pops under or overvoltage error. I can read the voltage, and it is truly under (6v) or over (58v) the treshold (which is wrong, because it should be 24v) , but can not start the motor. (The nominal voltage is 24 V) I can measure the divided bus voltage with its own ADC (but I can not use it separately, since it needs the ADC channels to drive the motor with different setup) . It is not an error of wrong parameters, I checked the Drive and Power stage sections both. Why is this error occuring to me, and what can I do, to determine the source of it? It seems to me, that the busvoltagesensor class is not working, because it reads the bus voltage, but that voltage is wrong. What can I do about it? 

Posted on June 02, 2017 at 21:07I have several successful designs with STM32 PMSM FOC LIBv4.0, but from time to time I noticed some irregularities, causing the motor to 'click' while spinning (1kW PMSM). It sounds like someone is hitting it with a small hammer. This happened seldomly, and I never could reliably reproduce it in the past, in order to track it down.Last week I had this situation again, and it happened frequently enough to allow finding the root cause. It turned out to be the library module dealing with the encoder feedback, in combination with a noisy electrical encoder signal. It turned out that the (v.4.0) library module cannot handle a noisy encoder feedback that causes temporary direction reversals. When this happens simultaneously with a timer overflow or underflow, then it calculates wrong speed information, which is causing the 'clicks'.I have revised the entire encoder module (ENC_F4xx_SpeednPosFdbkClass.c, ENC_F4xx_Sp

Posted on February 29, 2016 at 20:28We use the motor control library STM32 PMSM FOC V4.2 .For current control using 2 ICS, but of all the formula to calculate the current , torque used  value of Rshunt(Ohm) and AmplificationNetworkGain. Current[A] = [Current(s16A) * Vdd micro(V)] / [65536 *Rshunt(Ohm) * AmplificationNetworkGain]... How to solve this problem? P.S. All boards STM  use  shunt resistors as current sensors

Posted on December 20, 2015 at 11:09Hi, Does the motor control software suite (STM32 PMSM FOC LIBv4.2) support STM32F401, '411 and '446 processors? When I tried it, it didn't allow another option for CPU clock than 168, and as far as I know the above processors support 84, 100 and 180MHz. (because of the ''advanced'' features that I want to use I seem to be pushed towards the higher end processors, the 4xx series. And a '405 seems overkill to me). 

Posted on December 17, 2015 at 18:17Hi, I have the IHM001 motor control kit. I managed to compile the 6step example from  STM32CubeExpansion_SPN7_V1.0.0 . I'm using Linux, and I managed to create a Makefile for the example project.For FOC it seems I have to use  'STM32 PMSM FOC LIBv4.2', but there I see just a few stmcx files referencing my IHM001. Where can I find sources for an example for my board? For example, the sources to the pre-installed app on the included '302 nucleo would be nice. (to prevent messing up that pre-installed app, I use my '401 nucleo for testing at the moment.)

Posted on August 20, 2015 at 11:00Hi all,I'm using Rowley Crossword IDE for MacOS and i have issue with compiling WEB FOC v4.1.0 project (import from Keil uVision project). Always when i try to build project  i get this error: ''Can't open /PROJECT ADDRESS/BUILD CONFIGURATION/tmpdFtZGh for reading''. I used FOC v4.0 in Rowley CW and everything is OK. I checked access rights and seem's to be OK.Do you have any idea to solution? Thanks for your help and time Ondra

Posted on April 06, 2015 at 14:55 Hi, I'm using ST PMSM FOC 4.0 with STM32F303RB and Hall sensor. Hall sensors are on PORTC pins 6, 7 and 8. Used as TIM3 channel 1-3 inputs. Code is generated from the MC workbench. Symptom is - hall sensor signals are pulled low by the MCU. So i digged into peripheral registers with debugger and found that PC6, PC7 and PC7 have alternate function 1 which is EVENTOUT. They shoulduse AF2 which is TIM3_CHx. In library header file called SystemNDriveParams.h there's a struct which is initialized with Hall sensor alternate functions. There's also a default AF assignment: /* TBR after final test with WB */ #if !defined(H1_GPIO_AF) #define H1_GPIO_AF GPIO_AF_1 #endif #if !defined(H2_GPIO_AF) #define H2_GPIO_AF GPIO_AF_1 #endif #if !defined(H3_GPIO_AF) #define H3_GPIO_AF GPIO_AF_1 #endif As the H1/H2/H3_GPIO_AF are not generated by workbench then they get the default values (AF1).

Posted on October 29, 2014 at 11:24Hello This is just an information for the developers and the rest of people. I'm working right now with STEVAL kit IHM039V1 for dual motor. I found that LCD code works only for single drive. Problem is probably in wrong file that is distributed with FOC library 4.0. Both hex files have the same size - see attached picture. I solved this issue by compiling LCD project my self. But there was another problem with wrong definition of MCU constant for compiler - see attached file. It was STM32F40X. I had to chang it to STM32F40XX to compile the project without errors. Daniel #foc-4.0-dual

Posted on September 22, 2014 at 23:27Hello guys,I am trying to use STM32 PMSM FOC v3,4 with STM32F107VCT6 MCU. Is it possible?I previously used the library with STM32F103 mcu. I compared the f107 with f103 and found that they are almost the same (except 107 has more peripherals). So I used the same configuration as was on f103, but the board is not responding. I noticed that f107 has 25MHz oscillator, but in ST motor control workbench there is only 8MHz option. Could this be the problem? Is there any way to fix this? Or simply f107 can't be used with PMSM FOC library?Thank you for your responses and help.Have a nice day. #motor-control-f107

Posted on August 08, 2014 at 12:31Hello, I would like to use the latest FOC library for small PMSM motor. I'm using STM32F303VCT6 MCU and I would like to use internal PGA. But motor doesn't run at all. Start sequence starts, but with very high current consuption (higher that I set in WB). I finaly fount that probably AD converter doesn't give a correct value. I see it mainly on Vbus voltage measurement. Measured value is not correct. It shoul be ~325V but reading from MCU give me a value ~189V and it fall down to ~21V after few seconds. Voltage on board is corrent, also MCU ADC works correct - I mean nothing is damaged on the board. I've check it with modified example project in StdLib for STM32F3 and it converts value from Vbus pin. So it seems to me, that something is wrong with setting of AD converter in library. ADC does not measure correct values of Vbus and probably also phase currents and that's why motor has during start so b
