5-3-4. Input terminal assignment
1. The number of high-speed counting channels of XG series PLC is shown in the following table:
PLC model
High speed counter channels
Incremental mode AB phase mode
XG1 16 points 4 4
XG2 26 points 4 4
2. Definition of high-speed counting input terminal:
The meaning of each letter is:
U A B Z
Counting pulse input Phase A input Phase B input Z-phase pulse capture
Note: The Z-phase function is still under development.
Under normal circumstances, the input frequency of XG1 series high-speed counting terminal can reach 80kHz
and 50KHz in single-phase and AB phase modes respectively. The highest frequency of XG2 series high-speed
counting terminal can reach 200kHz in single-phase and AB phase modes. When the X input is not used as a
high-speed input port, it can be used as a common input terminal. In the frequency doubling item in the table,
"2" means fixed double frequency, "4" means fixed quadruple frequency, "2/4" means adjustable. The specific
port allocation and functions are shown in the following table:
