FDT is used to check inverter output frequency,when output frequency is greater than frequency detection
value,FDT effective,when output frequency is less than frequency detection value*(1- Frequency detection
hysteresis),FDT ineffective;whenoutput frequency is between the above two,FDT output keep no
change,following is FDT chart
