Current sensing with inverting amplifier

Hi,

I have been trying to use FOC SDK 4.2 with existing hardware. The board uses inverting amplifier instead of non-inverting ones. Anyone got an idea on how to modify the code?

So far I've tried:

1. use negative value for amplifier gain: doesn't work

2. use negative value for current shunt: doesn't work

3. use negative gains for the current loops: stable current loop, but will trigger ''speed feedback'' fault.

Thanks!

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).
