Chapter 3 PLC System Configuration & Settings 3.6.2.6 Options - Incremental Encoder 1 The page below is for the first set of device settings. Parameters settings include resolution, integration method and frequency multiplication. Incremental Encoder 1 Resolution The default value of incremental encoder 1 resolution is 1024. Incremental Encoder 1 Integration Method The settings include forward and reverse direction. Incremental Encoder 1 Frequency Multiplication The settings include one/ two/ four times frequency multiplication. The integration method and frequency multiplication is explained in the following table.
3-225 Integration Method Meaning Counting Method One time frequency multiplication in forward direction The counting starts when phase B rising edge is detected. Increase the count Two times frequency multiplication in forward direction The counting starts when phase B rising and falling edge is detected. Increase the count Four times frequency multiplication in forward direction The counting starts when the rising and falling edge of phase A and B are both detected. Increase the count One time frequency multiplication in reverse direction The counting starts when phase B rising edge is detected.
Decrease the count Two times frequency multiplication in reverse direction The counting starts when phase B rising and falling edge is detected. Decrease the count Four times frequency multiplication in reverse direction The counting starts when the rising and falling edge of phase A and B are both detected. Decrease the count
