5 input specifications and wiring methods
5-3-3.Input Terminals Assignment
1、High Speed counters Assignment of XC series PLC:
2、Input Terminals of HSC:
Each letter’s description:
U Dir A B
Counter's pulse input
Counter's direction judgment
(OFF: increment counter, ON: decrement counter)
A phase input
B
Normally, X0, X1 terminals’ input frequency can reach 80KHz under single-phase and AB
phase mode; the other terminal’s input frequency can reach 10KHz under single-phase mode and
5KHz under AB phase mode. If X input terminals are not used as high speed input port, they can
be used as common input terminals. The detailed port assignment is shown below:
