When there is a counter over-flow, the value will jump from 16#FF to 16#00.0 1 Incremental Encoder ModeInput 1(3) and input 2(4) will be used as an incremental encoder withAB quadrature mode and X4 encoding.1 1 PWM Time Measuring Mode(High-Time in μs, Period Time in μs)Data bit Designation DescriptionB3 B20 0 Input 3/4 Counter Mode0 1 Incremental Encoder Mode1 1 PWM Time Measuring Mode
