Using FOC Algorithm with Nucleo-F302R8 and IHM07M1 (3 shunt) gives Over Current error in Motor Pilot when Motor is run

Why do I see an overcurrent error in Motor Pilot when trying to configure my boards for FOC algorithm? I am using the 3-shunt configuration with Hall sensor.

Dear ABart.5,

Firstly, we would like to sincerely apologize for the delay in replying to your post.
If your point is still pertinent, could you please answer the following questions:
- Does the HW 1 or 3-Shunt configuration in line with FW configuration?
- Does the motor start to spin before Over Current?
- What is your motor max current? Is-it higher than power board max current (2.8A for IHM07M1)? If yes, workbench will use power board value as a limit. Maybe you can try by limiting motor current to 2.2A e.g.

If you agree with the answer, please accept it by clicking on 'Accept as solution'.
Best regards.
