Functions Used: High-speed Counting for a Built-in Input
A high-speed counter input can be used by connecting a rotary encoder to a built-in input. A CP2E
CPU Unit is equipped with more than one high-speed counter input, making it possible to control
devices for multiple axes with a single PLC.
High-speed counters can be used for high-speed processing, using either target value comparison
or range comparison to create interrupts. Interrupt tasks are executed when the counter value
reaches a specific target value or range
.

Operation Overview
A sheet feeder is controlled to feed constant lengths in a given direction, e.g., for vacuum packing of
food products.
While the pulse count is between
3
,500 and
3
,550, normal stop position output (CIO 100.02) will be
ON. If the pulse count exceeds
3
550, the error stop position output (CIO 100.0
3
) will turn ON.
