Features and Main Functions
Section 1-1
Full Complement of
High-speed Counter
Functions
High-speed counter inputs can be used by connecting rotary encoders to the
built-in inputs. The ample number of high-speed counter inputs makes it pos-
sible to control a multi-axis device with a single PLC.
• Four 100 kHz (single phase)/50 kHz (differential phases) high-speed
counter inputs (4 counters/2 axes) are provided as a standard feature.
(See note.)
Note
Settings in the PLC Setup determine whether each input point is to
be used as a normal input, interrupt input, quick-response input, or
high-speed counter.

speed Counter Functions
High-speed Processing for High-speed Counter Present Value (PV)
Target Values or Range Comparison Interrupts
An interrupt task can be started when the count reaches a specified value or
falls within a specified range.
High-speed Counter Input Frequency (Speed) Monitoring
The input pulse frequency can be monitored using the PRV instruction (one
point (counter 0) only, and you must select whether to use input frequency
monitoring or counter 3; you cannot use both).
High-speed Counter PV Holding/Refreshing
It is possible to toggle between holding and refreshing the high-speed counter
PV by turning ON and OFF the High-speed Counter Gate Flag from the ladder
program.
