Example for STEVAL-ROBOT-1 (EVALKIT_ROBOT_1_SDK543_Positioning_LL) - two main issues.

Hi,

I'm try to use example provided by ST - EVALKIT_ROBOT_1_SDK543_Positioning_LL.

After few little correction the project (i.e. modbus was added to project using absolute path, not relative using project location), example is working, but:

1.

On the start, motor sets 0 position (I'm reading this position using function MC_GetCurrentPosition1()) and motor stays at this position. But if I rotate motor by hand over 20.5 radians, then motor suddenly run in this direction and stops at 40.84 radians. I can do it once more time, in the same direction, and result is that motor stops at 82.03 rad, and so on. When I do the same thing to 0 position direction it returns with the same few steps and returns exactly in 0 rad pos.

2.

The example configuration STEVAL-ROBOT-1 us very low current, something 0.07A.

Do You know, how to fix those issues?

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK). 

Best regards
