Usage of field weakening

3 years 6 months ago #29534945 by hernajou
I am using the controller FBL2360 to drive a brushless motor, the objective is to drive it above its base speed by using the field weakening technique, but if I understand correctly, the motor must be operated in torque mode for this, so I have the next questions:
1. How can I request a higher speed in torque mode if the max current was already reached and the speed is not a parameter to be controlled in this mode?
2. There is in the manual an example of the field weakening dependent of the speed, but it doesn´t explain how the motor starts to rotate and which command keeps increasing the Speed, could you give me an example more complete?
3. The command GID is to be used together with other commands?
At the end, I would like to graph something like the attached curve

Thank you for your Support!
