IuseFPGA drivead2s1205 for testingfaultdetectiondelaytime. When EXC,SIN, COS ar NC, thefaultdetectiondelaymaximum value isnot125us, but800us;iftheEXC SIN connect resolver signal,COS NC, the faultdetectiondelaymaximum value is about24ms.
I wonder what the main reason for this phenomenon, and how to judge whether the the Rotarytransformerhasbroken?
May I know what CLKIN frequency. The tracking rate, the tracking loop bandwidth and excitation frequency would vary with the clock frequency. The 125us in the datasheet was under the condition of CLKIN = 8.192MHZ.
