Detailed instruction of parameters 
FDT1 electrical level 
detection value 
When  the  output  frequency  exceeds  the 
corresponding frequency of FDT electrical level, the 
multi-function  digital output terminals  will output the 
signal  of  "frequency  level  detect  FDT"  until  the 
output  frequency  decreases  to  a  value  lower  than 
(FDT electrical level—FDT retention detection value) 
the  corresponding  frequency,  the  signal  is  invalid.

Amplitude value for 
frequency arrival 
detection 
When the output frequency is among the positive or 
negative  detection  range  of  the  set  frequency,  the 
multi-function  digital  output  terminal  will  output  the 
signal of "frequency arrival", see the diagram below
