Hello:

How do i change the number of radix point bits of ePWM blocks, cos and sin functions. i find it to be 1 radix point bit. why can't we change it and how do i know if over flow exists in run time.

Regards, MALA

The ePWM block will accept inputs from 1.16 to 8.16 and do the right thing. fxSin and fxCos are constrained to produce 1.16 outputs if they are connected to 1.16 values, or 1.32 if connected to 1.32 values.

When i drag ePWM block from piccolo block set, i get ePWM block with 1.16 precision, how could i change this.

Yes, the block inputs do say 1.16, but they will accept 2.16 with no problem.
