Change axis step pulse width - NI 7340

Hi,

I'm controlling a stepper motors with a NI-7340 and UMI 7774 without feedback.  With MAX I've configured the interface and I can see the step & dir waveform on the scope.
But, the step pulse is only 20us wide and my motor driver does not see it.

How to increase the pulse width?   I have tried using Set u32.flx in LabVIEW, but the pulse width has not changed.  I have attached the VI and MAX configuration (zip file).

Please help me.

 

Thanks.
