    FL6112 dual-channel incremental encoder detection module Application example 5 Application example This chapter takes CODESYS as an example to introduce the usage of the product. Step 1 Add the FL6112_2EI device. Step 2 Choose Startup Parameters, set the counter, filtering mode, encoder resolution, and counter preset values based on the actual needs, with a filter unit of 0.1μs.
  • Page 12 FL6112 dual-channel incremental encoder detection module Application example Cntx Cfg(x=0,1) is the counter configuration parameter of type UINT. Taking the counter 0 configuration as an example, the data definition can be found in the parameter description. Name Description 00: A/B phase quadruple frequency; 01: A/B phase Bit1–bit0...
  • Page 13 FL6112 dual-channel incremental encoder detection module Application example Cntx Ratio(x=0,1) is the encoder resolution (number of pulses fed back from one revolution, i.e. the pulse increment between two Z pulses). Assuming the resolution labeled on the encoder is 2500P/R, the Cnt0 Ratio should be set to 10000 since the Cnt0 Cfg is configured as A/B phase quadruple.
  • Page 14 FL6112 dual-channel incremental encoder detection module Application example According to the configuration value 788 of Cnt0 Cfg mentioned above (enabling DO to output pulse 8ms when the comparison is consistent), when the count value Cnt0_Val is equal to 1000000, DO0 will output 8ms.
