KEYENCE KV Series - Manual (Page 4)

Features of the Visual KV Series
● Extremely small
The Visual KV Series is the smallest in the world among AC type PLCs equipped
with screw terminal blocks, and saves installation space.
● Extremely fast
The minimum scan time is 140 µs and minimum instruction execution time is 0.7
µs, which is the fastest control in its class.
● AC power built-in type newly added
AC power built-in type units are newly added. This type can be used in small
spaces where a switching power supply unit cannot be installed.
● Excellent Access Window
An Access Window with two-color backlight is adopted in all models to facilitate
changing and monitoring of device data. Changing between RUN mode and
PROGRAM mode, checking the error code when an error has occurred, etc. can
be performed in a Visual KV Series unit without the need for any handheld
programmer.
The analog trimmer, which has been popular in the conventional KV Series, is
digitized to enable more detail settings. [Digital trimmers]
● User message setting function
In the Access Window, 256 different user messages can be displayed. This
function can be used to give instructions on works on the production line, indicate
abnormalities in the units, etc.
● Program write in RUN mode
Ladder programs can be changed even while the system is running.
● Equipped with two serial ports
Visual KV Series basic units are equipped with two serial ports to connect periph-
eral units, improving the debug environment.
(The KV-10xx is equipped with only one serial port.)
● Easy Ramp-up/down control function
The one-axis motor control function is offered separately from high-speed
counters so that feedback control is enabled.
● Equipped with two 24-bit high-speed 30 kHz, two-phase counters
The Visual KV Series is equipped with two high-speed counters each with a two-
point comparator output function that enables high-speed encoder input.
● Specified frequency pulse output function
High-speed counters can function as pulse oscillators of 50 kHz maximum with
easy setting, without creating a complicated ladder program.
● Frequency counter function
High-speed counters can function as frequency counters with easy setting,
without creating complicated ladder programs.
● Cam switch function
High-speed counters can function as cam switches with easy setting, without
creating complicated ladder programs.
