Features and Main Functions
Section 1-1
Note
If high-precision positioning is required, we recommend using an inverter with
vector control.

High-speed Counter
Functions
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.
• 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.)
• For CP1L-J PLCs, four 20-kHz (single phase)/10-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.
A virtual pulse output is created using a pulse output instruction, the position
offset is calculated using an error counter, and a frequency (i.e., speed)
command is output according to the position offset to control positioning.
