Simulink Library "svm_std_flt" output saturation to square wave

Hi all, 

 

I'm trying to simulate the FOC of PMSM with simulink. Could anyone please explain why the "SVM_STD_FLT" saturates to [0 ; 1] output values (instead of the standard output waveform shown in the figure below). 

I'm using a float Park Inverse Transform that has a floating input/output (not in the range [-1, 1] ) by doing so, the SVM block outputs a saturated square wave duty cycles. 

 

any help! 

 

Thanks, 

Abdelmouneim.
