TMS320F280025: Motor Control SDK - Current reconstruction for overmodulation

Hi,

I'm using the Universal Motor Control Lab to drive a motor in speed control. In the user_mtr.h is stated, that for USER_M1_MAX_VS_MAG_PU > 0.5 the current reconstruction is necessary and it referenced to Lab08, but there is no Lab08 in the project.

So, how can I use the current reconstruction, so that I can overmodulate the motor?

Edit: There is the MOTOR1_OVM flag that enables the OVM. When I now run the motor, it still seems to make the same noise as when I don't use any OVM and run the motor in OVM mode (USER_M1_MAX_VS_MAG_PU > 0.5). Do I need something else to activate the OVM in the MotorControl SDK universal motor control lab correctly? Does OVM only brings an advantage, when there are less than 3 shunts?
