current limit for b-g431b-esc1

[cz]

Hello,

i'm using a b-g431b-esc1 with a 12 V sm-pmsm motor. After running the motor profiler and the motor control workbench, i've played with the cube ide. I have noticed the motor doesn't draw more than 1,6 A, but max current was set to ~5 A in the motor profiler. In pmsm_motor_parameters.h is a define for the nominal current which is set to 1,6 A, but changing it doesn't seem to affect anything. Do you have any ideas how to approach the problem?

Greetings

Here some additional context:

• i'm using hall sensors to control the motor
• 40 A current peak is allowed with this motor
• when under load, instead of drawing more current and holding it's speed reference, it's power consumption and speed decreases

The question has been moved from the "STM32 Motor Control" section to the "Motor Control Hardware" section (the question is not about the STM32 MC SDK). 

Best regards
