Counting pulse input
Phase A input
Phase B input
Under normal circumstances, the maximum frequency of XSDH and XS3 series high-speed counting terminals
can reach 200KHz in single-phase mode, 100kHz in AB phase mode for XSDH and 200kHz for XS3. XSLH
can up to 1MHz in differential mode, 80KHz in single phase mode and 50Khz in AB phase mode. When the X
input terminal is not used as a high-speed input port, it can be used as a common input terminal. The specific
port allocation and functions are shown in the following table:
