4.7 HIGH SPEED COUNTERS SPECIFICATIONS
AND WIRING
High-speed counters use input terminals X000 to X007 of the main unit
for inputs, and offer counting up to 60kHz (1 phase).
Input terminals not used for high-speed counters are available for
general-purpose inputs.
For details on programming, refer to the HELP section of GX Works2.

EXAMPLES OF EXTERNAL WIRING (ROTARY ENCODER)
1-phase 1-input [C235 to C245]
The following examples of wiring apply to the cases where C235 is
used. When another high-speed counter number is used, wire the
counter referring to the following diagrams. It is recommended to use
shielded twisted-pair cables for connection cables. Ground the shield
of each shielded cable only on the PLC side.
1) NPN open collector transistor output rotary encoder
2) PNP open collector transistor output rotary encoder
2-phase 2-input [C251 to C255]
The following examples of wiring apply to the cases where C251 is
used. When another high-speed counter number is used, wire the
counter referring to the following diagrams.
It is recommended to use shielded twisted-pair cables for connection
cables. Ground the shield of each shielded cable only on the PLC side.
1) NPN open collector transistor output rotary encoder
2) PNP open collector transistor output rotary encoder
