X-NUCLEO-IHM07M1 MC WORKBENCH Fault Problem

[robotype]

Greetings.

I started to study motor control with X-NUCLEO-IHM07M1 as following

- MCU : STM32F302R8

- PowerBD : X-NUCLEO-IHM07M1

- Motor : Bull Running BR2804-1700Kv

I just try to make STM32Cube IDE project using MC Workbench 6.4.1 (as described following screenshot image)

but, Using ST Motor Pilot, When start command is on, just motor starts rotate 1 cycle, and stopped. Then, Status Occurs "FAULT_OVER" as following screen image 

And, main function is no codes for opreating because of just test with ST Motor pilot

Can I ask help for what is problem?

As Using MC Workbench Version 5.4.8, motor works.

Is any difference between MC Workbench 5.4.8 and 6.4.1?

Hello @robotype,

Driver protection error indicates an overcurrent detection on the power board side.
Do both MC Workbench 5.4.8 and 6.4.1 use cases have the same configuration? Do both use the same current sensing topology (3-shunt or 1-shunt)?
Can you provide your .stwb6 file?

[robotype]

Thanks for attention.

I make same configuration (just choosing right board, control, motors) and both use the same current topology (3-shunt)

I attachted .stwb6 files as made from workbench 6.4.1.

Hello,

On your .stwb6 file, the Driver Protection setting has been modified from BKIN to BKIN2.
As mentioned in the Workbench tool:

I know, but it does not worked BKIN as with BKIN2.

i just tried to change BKIN to BKIN2 because of it doesn't worked.

I think another reason may be..

Hello @robotype,

With your 6.stwb6 file, TIM1_BKIN selection, and an R49 unmounted IHM07 board, I am able to start the Bull Running BR2804 motor. The current has been decreased as shown below.

it worked after unmount R49, but motor starts and stopped during 1 second. speed feedback error and fault occurs. it may be speed limitation problem.

1. why it works with ummounting R49?

2. how to fix speed feedback error and fault signal occurs

Hello @robotype,

I only mentioned that R49 was removed from my board (not relevant to your issue).
