TMS320F280025C: Universal Motor Control Lab - Iqd Integrator Problem

Hi

I'm using the UMC (Universal Motor Control) project from the SDK V.4.0.0 and I figured out, that when the motors BEMF reaches the speed to be equal with the supply voltage,

the integrator of the piHandle_Iq goes immediately in saturation and the Iq/Id currents spikes a lot, because it cannot be controlled anymore. 

So there should probably be a concept to prevent the saturation of the integrator at speeds close to the BEMF equal supply voltage speed, does TI provide something there?

Thanks
