I found the failure, I has insert a bus conversation on the output from my IIR with "signed int 16-bit in/out and make settings in DPRAM also signed int 32x16 bit and not inferred.

The reason was, I has to large information with always inferred settings, but is not important at the output from my IIR, when the signal is 205.12584 or only 205.
