Features and Main Functions
Full Complement of
High-speed Counter
Functions (All
Models)
High-speed counter inputs can be enabled by connecting rotary encoders to
the built-in inputs. The ample number of high-speed counter inputs makes it
possible to control a multi-axis device with a single PLC.
• X and XA CPU Units
Four 100-kHz (single phase)/50-kHz (differential phases) high-speed
counter inputs 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.
• Y CPU Units
Along with two 100-kHz (single phase)/50-kHz (differential phases) high-
speed counter inputs, two 1-MHz (single phase)/500-kHz (differential
phases) dedicated high-speed counter terminals are provided.
