I'm using a STEVAL-SPIN3202 to control a 15W BLDC sensorless motor. I'm unable to spin a motor using six-step driving mode and I'm assuming it's because the motor's configuration needs to be updated. Looking at the #defined MC_SixStep_param_32F0.h configuration file the only motor parameter that I can find is the number of pole pairs. Is there an…(Show moreShow less)
Hi, We are working on power consumption measurement implementing the stpm10 with a Steval IPE017V1. There is some informations missing in the datasheet at config register description about the CHP register. It should be a 8 bits register. 16 bit are assigned for it and the corresponding description is about some other unknown register: CHS I…(Show moreShow less)
Hello,I am using L6472 to control stepper motor. When i apply step clock mode command to L6472 , motor gets hold but during this opertion Motor shaft move by 1 to 2 degree , What is the reason of shaft movement after applying STEPCLOCK mode command?
The controller might zero to the nearest "zero" electrical position, meaning the closest full step position, when switching to step clock mode. Its like when giving the hard stop command for the first time when the bridge was in high impedance mode, the motor switch to hold and the shaft makes a slight move as it locks to the nearest zero…
I am experiencing some issues running the FOC SDK v4.3. My HW-setup: Control board: NUCLEO - STM303 (ST part number) Power board: X-NUCLEO-IHM08M1 (ST part number) PMSM motor IDE: IAR Currently I am able to compile and download code to the F303RE, however the motor only spins a short period of time, and then stops, requiring a reset…(Show moreShow less)
I forgot to update this forum. The error was actualy in HW, I had switched the not connected the phases of the motor properly. Nonetheless, a port to from 303C project to F303RE as MCU should be done in IDE, such as IAR Embedded Workbench as you also suggested. The motor is now up an running with sensor-less and encoder.
I see that there is a difference in the number of microsteps and if they drive/control voltage or current, but is there any other difference? Could please somebody give me a quick comparison between them? I originally bought L6474 as I thought that is the most advanced (increasing numbering), but I figured out from one of the 7 datasheets and…(Show moreShow less)
If you want to use drivers (like the L6480 or L6482) that use external mosfets there is a crucial rule that must be taken into account and that is the total gate charge (Qg) of the mosfet. This determine the amount of current spike the driver needs to supply into the gate of the mosfet to be able to turn it on properly. According to the L6480 or…
Enrico Poli l6235 l6235pd bldc I have the same observation regarding speed control using the L6235 VRef Input. It is extremely difficult to establish a user-friendly range on VRef Input to get a full scale speed control. PWM switching the FWD/REV Input is one workaround, but the switching causes the motor to hum and does not feel like an…
Hello, I'm very interesting in trying the new STSW-ISA172V2 board. Firmware of both MCU are provided as binary, but anyone knows if it is possible to get the source code, to customize the firmware ? Or do you know any PFC control library for STM32 ? Thank you for any help ! Theo
