DRV8350H-EVM: Software sensorless tuning issue

Hello,

For our battery-powered smoke extraction fans, we want to develop a brushless motor driver 1.5KW.

For a new development we want to use the reference DRV8350H.

We plan to start our development work with the DRV8350H-EVM circuit board.

I have a problem with the start sequence, we use the firware SLVC755 sensorless withe the board DRV8350H-EVM.

The motor runs correctly without load.

With the load (a propeller for a fan) I can't get the motor to start I have an overcurrent error.

Which parameter is problematic ?

My configuration :

My result with the overcurrent error :

Thanks.for your help.
