MP6540H fault conditions

Hello! I am using the MP6540H driver in one of my products (24V DC bus) but I noticed that the nFault goes low much too often. I run the motor at low speed for a few seconds, the temperature is very low, the PWM duty cycle is always below 20%, the current monitored at the SOx pins never goes above 0.45A and yet the nFault is triggered very often. What are other possible error conditions?
I have a HW filter on the SOx outputs, so maybe the instantaneous current might be a bit higher. If that’s the issue, although unlikely given the very slow motion profile, is there a way to filter possible very short current peaks from triggering the error?
