STM32 MCUs Motor control

When I use ST MC workbench to generate or update, it have error.Please help to solve this problem

Hi,We're using the STEVAL-SPIN3201 dev board and trying to control it form the MCSDK GUI on windows. Currently whenever we run the motor closed loop (FOC) using the hall sensors a speed feedback fault is returned. We've also tried running the motor in open loop (sensor-less) and a startup failure fault is returned. For our application we require low rpm rotation (~10 rpm) with high torque. I've included photos of our current motor params and pictures of our motor.Regarding the speed feedback error based on previous user posts it seems that this issue is due to incorrect 'Placement electrical angle'', 'Sensor displacement' or noise on the sensors.https://community.st.com/s/question/0D50X00009XkhhZ/speed-feedback-fault

i have tries many times with changing all parameter, setting current gains values etc but still it showing over current in all condition.. can any one help me to solve this issue.

Posted on April 07, 2014 at 18:06Hi I'm working with the STM3240G-EVAL Board and trying to drive a BLDC Motor from Maxon EC-max 30 type 339923 (maxon.com) On the motor side I have Hall sensors and an encoder with 500impulses / turn, 2 channels A+B and the Z channel. I used the ST Motor control workbench to set the parameters and IO PINs. Target Lib is SDK v3.4. I'm wondering why I don't need the HALL sensor signals to detect the correct angle of the motor. My problem is now, that I have not a sine current on the motor phases and i can't change the speed of the motor... How can I tune the PID parameters from the speed controller and the PID parameters of the clarke and park transformation? I really need help as soon as possible because I need to getting run with this motor as soon as possible. I hope that anyone can help me. The Plot from the oscilloscope is from the turning motor, the yel

Posted on December 19, 2011 at 14:49I used to developing a servo driver with PMSM FOC SDK 2.0 in STM32F103 MCU. And I wanna make a new control board with STM32F417ZG because of its floating point unit. Can I use the SDK2.0 in F4 directly or do something. I can't find any migration information between F1 and F4 on ST website. And I plan to update the SDK from 2.0 to 3.0, but I can�t get the source code of PMSM SDK3.0 from Chinese distributor, so can someone send me the source code. Thanks a lot. #condiential-web-distribution

Posted on January 06, 2012 at 05:55  I wanted to verify that when my HW over current circuit asserts the over-current signal that the effect on the software is the same as an ESTOP. Or does this input act like a chopper and only terminate the PWM signal for the cycles that the signal is asserted? Thanks, Eric

Posted on March 21, 2012 at 16:45Hello all, I tried to use the USB to serial interface SDK for the STEVAL-PCC009v2 dev board to write a custom driver for the L6470 (EVAL6470 board). The included library SPI_SDK.dll works fine, but the command: DFU_GoTODFUMode() from the DFU_SDK.dll to get the board in DFU mode gives an undocumented error: 7 and does not work. Is there a solution for this problem?

Posted on July 04, 2012 at 08:04I can't find the PMSM SDK V3.2 but it referred in UM1052 : STM32F103xx/ STM32F100xx/STM32F2xx/STM32F4xx PMSM single/dual FOC SDK v3.2

Posted on September 06, 2012 at 15:37Hi, I work on motor control with  : ''STEVAL IFN003V1''. I've generate a file (.h) with all parameters with ''ST MOTOR CONTROL WORKBENCH''. But it's my first utilisation of library ''foc sdk 3.2'' Could you show me an example of a file (.c) for basic instructions (start motor, stop, ...), or a good tutorial ? Thank you Jean Ascot

Posted on September 12, 2012 at 15:59Hi, I work on atollic with stm32 foc sdk 3.2 for motor control. When I compil my project, I have always the same errors : ..\srcmain.c:40: undefined reference to `MCboot' ..\src/main.c:41: undefined reference to `MCI_ExecSpeedRamp' ..\src/main.c:42: undefined reference to `MCI_StartMotor' ..\src/main.c:44: undefined reference to `MCI_StopMotor'  but no problem with CMCI oMCI[MC_NUM], CMCT oMCT[MC_NUM]; I have linked all files .h with the main file. Could you help me? Thank you my code : #define PROJECT_CHK #include ''CrossCheck.h'' #undef PROJECT_CHK #if defined(PFC_ENABLED)   #include ''PIRegulatorClass.h'' #endif #include ''MCTuningClass.h'' #include ''MCInterfaceClass.h''

Posted on September 14, 2012 at 02:21I have an IPMM with absolute position resolver mounted on it. Unfortunately i can not use it even with decoder - absolute position to 12-16 bit paralel interface. Thats why i try to run in sensorless modes with 2 insulated current sensors. I tried with 3.0 and MCWB 1.2 but wasnt able to run the interrupts and the serial communication. After that i tried with 3.2 and workbench 2.0 and the FW compiled correctly. When try to connect MCWB 2.0 to FW 3.2 there is an error that says some version incompatibilities. I connect FW 3.2 (with parameters generated from MCWB2.0) with serial communication to MCWB 1.2. Then i have the motor spinning just for few turns. It behaves like that: First it runs DC for few miliseconds and after that it generates 9 sine waves with frequency 20 Hz and maximum voltage (PWM 0-100%). After that the motor stops and displays Speed Feedback Error. In one of 10 or 20 runs the

Posted on October 02, 2012 at 11:51I have changed FOC SDK V3.0 to work with a linear motor with analog hall sensor and these changes work so far with the STM32F103RC microcontroller. But actually I have planned to use STM32F205RB microcontroller for which the FOC SDK V3.0 isn't suitable. Therefore the question: when FOC SDK V3.2 confidential distribution will be released ?

Posted on November 04, 2012 at 11:19Hello... I do want to have motion contol with 3Phase induction motor with FOC algorithm. The FOC library(FOC SDK v3.2--UM1052) and software(ST Motor Control WorkBench) offered ST is for PMSM. I dont want to use Permanent Magnet motor I want to use induction motor. Its been said that UM0483 has control of ACIM but inthere is no library present for ACIM http://www.st.com/internet/com/end_application/908.jsp . Help me in this regards. Based on your reply I can stay with ST.com. Microchip company offeres Sensorless FOC for Induction Motor. I bought STM32F4 discovery and programmer from ST. I want to use ST for Induction motor since the FOC library is well established and you offered software for motor control. #foc-sdk-3.2-induction-motor

Posted on December 13, 2012 at 00:37Hi, I noticed that  STM32 MC FOC SDK V3.3 was mentioned in ST Motor Control Workbench V2.1 as one of the target libraries. I also found a http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/RELEASE_NOTE/DM00068242.pdf mentioning it. But, I couldn't find it being available for download on ST.com. Has it indeed released? If so, where can I find it? Thanks, Tamil

Posted on February 07, 2013 at 14:11Hardware: STEVAL-IHM023V2 + STM32100B-EVAL + custom motor Configuration: High-voltage 3-phase PMSM, IAR 6.50.2.4585, STM32 PMSM FOC Firmware Library v3.2 - WEB distribution I'm trying to get started with the example IAR project from the FOC firmware STM32F10x_Workspace.eww. Serial connection via Motor Control Workbench is running, I can see valid bus voltage and temperature. If I click the ''Start Motor'' button I can hear a soft click noise (it's not the relay of the inrush cuurent limit relay) and get the error status FOC duration fault. I use single shunt configuration because Motor Control Workbench says: ''Current sensing three shunt technique is not supported  by STM32F100 medium density.'' What's going wrong here? Thank you for any hints. #foc-stm32100b-ihm023v2-sdk3.2

Posted on March 12, 2013 at 11:10hi, I got the STM3210B-MCKIT and use the 3.2 FOC Lib + Workbench 2.0. I tried to get the Encoder control to work: - I jused the SDK32x-STM3210B-EVAL-MB459-Shinano.stmc - under Drive Management I changed the sensor selection to quadratur encoder - exported the settings to System & Drive Params - I compiled with IAR batch command my problem is that the motor dont start correctly, i often got a overcurrent fault. if its start it immediately stops. if i rotate the motor by hand, the measured speed seems to be correct.. what do i wrong? the hall sensor doesnt work also. the sensorless control work as expected. thanks

Posted on March 24, 2014 at 23:49Hi In the PMSP single/dual FOC SDK v3.4 RELEASE NOTE it says: 3. Known limitations in v3.4 ENCODER speed sensor function: one Input Capture pin of the selected timer must be grounded, according to the remapping in use and this rationale: IC4 in case of TIM2, IC4 in case of TIM3, IC3 in case of TIM4, IC4 in case of TIM5; I am using STM3210B-MCKIT (MB459) along with the supplied Shinano motor which has the capability of encoder feedback. In this setup, TIM2 would be used over MCU pins PA0-PA3, or in terms of peripherals TIM2 channels 1-4. According to the 'Known Limitations' then, it is required that PA3 (TIM2 Ch 4 (IC4)) is grounded. However I note that on that on the schematic diagram for the motor development kit (UM0426) that TIM2 Ch4 is not grounded - rather, it is used for analog voltage reading. I

Posted on March 25, 2014 at 01:02Hi The motor control SDK 3.4 provides me with an LCDProject, which I believe contains the binary for the communications interface to the Motor Control Workbench program. There doesn't seem to be any source code provided for this feature, and the MCWB program seems to offer no options for nominating the MCU USART or UART for use with that feature. Is there a way to customise that feature to use a different MCU USART/UART peripheral, or are we stuck with USART1? Thanks Luke #uasrt-mcwb-customise-serial
