Negative Current Issue

Hello,

Im using the FSESC 6.6 Board from Flipsky with the motor lehner 3080 -> http://www.lehner-shop.com/en/inrunner/series-30/3080.html

The motor is running in FOC mode sensorless but with an negative current. thus, the speed controller can't work and the rpm raises to max.

How I can avoid this? Does anyone have a solution for this strange behavior?

Thanks a lot!

Alex
