The P-NUCLEO-IHM03 with type selected as "FOC" has the firmware pre-installed. After pushing Blue start/stop button, the motor starts but fails to continue.
In Motor pilot, it is showing that a fault is thrown (startup failure) and the motor shuts down. The P-NUCLEO-IHM03 Black button needs to be pressed to clear the fault, but the motor still does not continue to run upon Blue button start.
Control Board: NUCLEO-G431RB
Power Board: X-NUCLEO-IHM16M1
Motor: Gimbal GBM2804H-100T

Also, please provide real time currents of an Open Loop project. At first in Open Loop voltage, and if it works, then in Open Loop Currents, that will help finding the root cause of the issue.

Just to confirm, you are referring this as "Open loop" right?
2024-06-14 03:04 AM
Yes, this is the Open Loop mode.
Concerning the User Manual of the IHM16, I am referring to this one : https://www.st.com/resource/en/user_manual/um2415-getting-started-with-the-xnucleoihm16m1-threephase-brushless-motor-driver-board-based-on-stspin830-for-stm32-nucleo-stmicroelectronics.pdf
The one you are referring to is the P-IHM03 pack User Manual.
And concerning the User Manual of the MCSDK, which contains a "How to use the Open Loop mode", I am referring to the one you can find via WorkBench by clicking on About -> Documentations -> Documentation -> in the newly open browser window, click on User Manual. Then click on Open loop description and usage.

Okay. Connections are set correctly as per the manual.
Open Loop Voltage Mode Ia and Ib Motor state is "RUN" but its not spinning.
Open Loop Current Mode, Ia and Ib, same thing happening:
Parameters:
What does this open loop result shows?

Hello tejas_amp,
For the usage of the Open Loop mode, please read thoroughly the dedicated entry in the MCSDK User Manual.
2024-06-14 05:12 AM
You had asked to provide real time currents. Those are there or is something other required?

Hello @tejas_amp
We pay a lot of attention to user experience and put a lot of effort into documentation. In return, we ask our users to spend the minimum amount of time necessary to read the documentation, and we are fully committed to helping you if anything is unclear and improving our documentation.
Is there some points in the open loop documentation you did not understand we can improve?
More accurately, could you tell me how we could improve this extract of the documentation?
Regards
Cedric

Hi, I have read & followed the documentation properly this time. Next time will make sure, this don't get repeat.
Below are the results of "Open Loop" Voltages and Currents by varying Vref and Fluxref parameters as speed of motor increases. I have varied them from V: 10 to 80 and Flux: 0.5 to 2 A. The motor state is showing "RUN" but motor is still and producing noise Please suggest further.
