1. High-speed counting of wafer rings
Use the KV Series to count wafer rings and display the count values.
[Control description]
The LV-11/LV-H32 digital fiberoptic sensor counts wafer rings. The count value is displayed on the KV’s
Access Window.
[Wiring example]
Count value display
The KV Series offers a high-speed scan time that make
full use of the capabilities of the LV Series, a digital
fiberoptic sensor providing high-speed response and a
small beam spot.
Connect the sensor to input 0000 of the KV.
Digital fiberoptic sensor
LV-11 + LV-H32
24 VDC
[Advantages of the LV Series digital fiberoptic sensor]
s Conventional method
A reflective photoelectric sensor is used for
counting. Malfunctions occur when the gaps
between the wafer rings become narrow. The
sensor should be re-adjusted at changeovers
between 6-inch wafers and 8-inch wafers.
s Advantages
The LV-H32, a long detecting distance and
small beam spot sensor, is free from
malfunctions. It can count both 6-inch and 8-
inch wafers with the same distance and
sensitivity settings. Re-adjustment is
unnecessary at changeovers.
The amplifier features a digital display and
allows for fine adjustment to obtain optimal
sensitivity easily.

To enable high-speed input, use the HSP instruction to set the input time
constant for input 0000 to 10 µs.
Wafer rings are detected with the LV and are counted with the built-in
counter of the KV.
Set the preset value as 500. When the count value reaches the preset
value, the counter will automatically reset.
When the count value reaches the preset value, output 0500 of the KV is
turned ON for 500 ms.
Using the high-precision 1-ms timer instruction (TMS) of the KV enables
time setting in the unit of 1 ms.
✩ When the count value reaches the preset

Two fiberoptic sensors monitor the sag of the material. Adjust the transfer speed so that the amount of the sag

The frequency counter function of the KV Series automatically calculates the
frequency of input pulses using the built-in high-speed counter CTH0. The
measured frequency (Hz) is automatically stored in DM1405 only when the
sampling time (ms) is input to DM1404 and special utility relay 2305 is turned ON.
The specified frequency pulse output function outputs pulses at a specified
frequency using the built-in high-speed counter CTH1. The pulses are
automatically output from output 0501 only when the output frequency (Hz) is
input to DM1936 and special utility relay 2306 is turned ON.
Synchronous control is performed by combining these two functions.
[Ladder program description]
Basic ladder program for tension control of hoop material
* This example assumes the use of the encoder with 360 pulses/rotation and the motor with 1000 pulses/rotation.
✩ Input time constant setting ✩
Specify the initial setting for the frequency counter function.
Sampling time: 1000 ms
To enable high-speed input, use the HSP instruction to set the
input time constant for input 0004 to 10 µs.
When the sag exceeds the upper limit of the sensor, the
unloader is operated at the speed of 120% to increase the sag.
When the sag is within the stable operation range of the sensor,
the unloader is operated at the speed of 100%.
When the sag exceeds the lower limit of the sensor, the
unloader is operated at the speed of 80% to decrease the sag.
✩ Initial setting of the frequency counter function ✩
✩ Change the transfer speed according to the sag
detected by the sensors. ✩
✩ Determine the output frequency (Hz) from the measured
frequency. ✩
The following expression is used to convert the values so that the numbers of rotation at the input and output sides
match.
Output frequency = Input frequency x No. of pulses in one motor rotation/No. of pulses in one encoder rotation
This example assumes that the motor provides 1000 pulses in one rotation and the encoder provides 360 pulses in
one rotation.

input 0000 and the one for reject
differentiation to input 0001.

✩ The ejection output is turned ON for

✩ Input time constant setting ✩
At the start of operation, execute an EI instruction to enable the interrupt
input/output function.
To enable high-speed input, use the HSP instruction to set the input time
constant for inputs 0000 and 0001 to 10 µs.
The ejection output 0500 is turned ON for 50 ms, then is turned OFF.
Using the high-precision 1-ms timer instruction (TMS) of the KV enables
time setting in the unit of 1 ms.
When input 0000 from the target detection sensor turns ON, the interrupt
program is executed immediately. If input 0001 from the differentiation
sensor turns ON during the interrupt execution, the ejection output 0500
turns ON.
The programs between INT and RETI are executed only when input 0000
turns ON. This is the same as the AND circuit program using inputs 0000
and 0001.
The interrupt input/output function can be used for various applications.
The interrupt input/output function is the best for quickly and accurately controlling the response speed between the

7. High-speed, accurate positioning of wafers
Use the KV for the positioning of wafers by detecting their notches.
[Control description]
Notch detection
Stop signal
Use the FS-V10/FU-12 fiberoptic sensor for wafer positioning.
When the sensor detects the notch, the KV immediately outputs a stop signal.
[Wiring example]
24 VDC
Fiberoptic sensor
(for notch detection)
Quick and accurate positioning is achieved
by using the interrupt function of the KV
and the FS-01 Series high-speed and high-
accuracy fiberoptic sensors.
Connect the sensor for notch detection to
input 0000 of the KV.
[Outline of interrupt I/O function]
In the interrupt processing, a process can be executed at
the instant of the interrupt, independent of the scan time.

of the KV offers the fastest
processing in its class: the input
time constant (target detection) is
10 µs max. and the interrupt
processing time is 40 µs max.
In addition, the KV features 16
points (max.) of input refresh
processing (direct input) during
interrupt execution and 4 points
(max.) of interrupt output (direct
output), which are helpful for reject
ejection.
The processing between the input
and output is only 70 µs or less.

[Ladder program description]
Basic ladder program for detecting wafer notches
✩ Initial setting of the interrupt input/output
function ✩
✩ When a notch is detected, a stop signal is
output. ✩
✩ The stop output is turned ON for 50 ms. ✩
✩ Input time constant setting ✩
At the start of operation, execute an EI instruction to enable the interrupt
input/output function.
To enable high-speed input, use the HSP instruction to set the input time
constant for input 0000 to 10 µs.
The stop output 0500 is turned ON for 50 ms, then is turned OFF.
Using the high-precision 1-ms timer instruction (TMS) of the KV enables
time setting in the unit of 1 ms.
When input 0000 from the notch detection sensor turns ON, the interrupt
program is immediately executed to turn on output 0500.
Always-ON relay 2002 is used as the execution condition for the programs
between INT and RETI. This is because the motor stopping output 0500
must be turned on whenever input 0000 turns ON.
The interrupt input/output function can be used for various applications.

8. Reliable counting of large numbers
Use the KV to count the number of pulses input from an encoder and display it with the KV-D20.
[Control description]
Count the number of output pulses (amount of movement) of the encoder connected to the KV, then display the
count value with the KV-D20. The value is displayed with a positive or negative sign to indicate the direction of
rotation (movement).
[Wiring example]
The 24-bit high-speed counter function of the KV allows for the
counting of large numbers.
Moreover, the KV features two points of two-phase input with a
maximum response speed of 30 kHz that enables a wider range
of applications.
For high-speed counter CTH0, connect phase A to input 0004
and phase B to input 0006. For CTH1, connect phase A to 0005
and phase B to 0007.
24 VDC

✩ Set the KV-D20 to display the result. ✩
✩ Write the high-speed counter instruction. ✩
✩ Input time constant setting ✩
Set the MEMSW instruction to use high-speed counter 0 as a 24-bit
counter.
At the start of operation, high-speed counter 0 is enabled in the double
multiplication mode and the current value is reset.
To enable high-speed input, use the HSP instruction to set the input time
constant for inputs 0004 and 0006 to 10 µs.
To enable the high-speed counter, input the CTH instruction.
Specify high-speed counter 0 as the device to be displayed on the first line
of the KV-D20 (#23000). Set the display attribute to disable changing
values ($8000) and to show signs ($0200) therefore ($8200)
* Setting a two-word display is unnecessary because the KV-D20
automatically recognizes the 24-bit high-speed counter and enables the
two-word display.
Contact comment setting to use the KV-D20 as a nameplate
Input a contact comment with “LADDER BUILDER for KV Ver1.5”, KV series’ ladder programming support software.
Half-width alphanumeric and katakana characters can be used.

10. Accurate positioning of transparent stickers
on a mount sheet
Use the KV Series for the positioning of transparent stickers by detecting them.
[Control description]
Detection of
stop position
Stops the motor.
Use the LV-21/LV-H42 digital fiberoptic sensor to detect the transparent stickers on a mount sheet. The sticker is
stopped at a specified position by controlling the motor.
When the sensor detects the end of the sticker, the KV outputs a motor stop signal immediately.
[Wiring example]
24 VDC
Digital fiberoptic sensor
LV-21 + LV-H42
Use the KV Series that offers a high-speed scan
time to make full use of the capabilities of the LV
Series, a digital fiberoptic sensor providing high-
speed response and long detecting distance.
Connect the sensor to input 0000 of the KV.
[Advantages of the LV Series digital fiberoptic sensor]
s Conventional method
The stickers are fed by steps using a one-pulse
motor, or a reflective photoelectric sensor is
used for detection.
s Advantages
• A wider range of sensitivity can be set.
• Detection is less affected by printing.

To enable high-speed input, use the HSP instruction to set the input time
constant for input 0000 to 10 µs.
Use the built-in positioning control function of the KV Series to operate the
motor.
Startup speed: 500 Hz
Operating speed: 1000 Hz
Acceleration/deceleration time: 1000 ms
Amount of movement: 4294967295 pulses
When input 0000 from the sticker detection sensor turns ON, the interrupt
program is immediately executed to reset special utility relay 2309.
At the reset of special utility relay 2309, the built-in positioning control
function of the KV Series forces the motor to stop.
Always-ON relay 2002 is used as the execution condition for the programs
between INT and RETI. This is because special utility relay 2309 must be
reset whenever input 0000 turns ON.
