Features
The K3NR Frequency/Rate Meter displays desired values after converting input
pulses.
The K3NR has the following functions.
Operating mode
Function
1
Displays rotational or circumferential speed of a single input.
2 to 5
Displays the calculation results of two rotational inputs.
6
Displays passing time calculated from the frequency and process length of a single input.
7
Counts and displays the number of pulses.
Measurement
The internal system clock counts the ON/OFF time (T) of sensor input or other
input and automatically calculates the frequency. The number of revolutions is
calculated from the result of the frequency multiplied by 60.
Sensor input pulse ON/OFF time (T) =
Frequency (f) =
1
T
• Rotational speed (rpm) = f x 60
• Circumferential speed = Circumference x revolutions
• Passing time = Length of processing/Circumferential speed
• Pulse counting
If there is any pulse input, the input will be automatically converted numerically
and displayed.
Prescaling
The number of input pulses is converted into a desired value.
Enables the K3NR to display the revolutions or rotational speed. It is necessary
to multiply the number of pulses per revolution or circumference by a certain factor. This factor is called the prescaling value.
Example:
K3NR
Proximity Sensor
rpm = f x 60 x a
f: Input pulse frequency (number of pulses per second)
a: Prescale value
If there are five pulses per rotation, the accurate rotational
speed can be calculated if a = 1/5 (– 0.2=2 x 10–1).
Comparative Output
Selection
Comparison output patterns can be selected from the standard, level, or zone
output depending on the application.
Refer to Comparative Output Patterns, page 80.
Linear Output
Refer to Linear Output Range, page 83.
BCD Output
A digital data output format where every four binary bits is numerically equivalent
to one decimal digit.
Refer to Section 7 BCD Output.
Communications Output
Refer to the Communications Manual.
HOLD
HOLD is an external input which is used to stop the A/D process and freeze the
display. The comparative, linear, and BCD outputs are also retained.
Refer to 5-3 External Input Signals for details.
2
Section 1-1
Features
RESET
RESET is an external input to reset the present max./min. values and counting
values. The process value when the RESET is ON is set as the maximum and
minimum values. The counting value is reset to zero. The max./min. values and
counting values can be reset using the front panel keys.
Refer to pages 104 and 105.
Teaching
The K3NR is provided with a teaching function that can set an actual measured
value as a setting value without key input.
This function is useful for setting parameters while checking the operating status
of the K3NR.
The teaching function can be used to set the set and prescaling values. It can be
also used to set the linear output range of the K3NR with a Linear Output Board.
Refer to 6-1 Teaching Function for details.
Output Test
This function is convenient for checking a system to which the K3NR is connected, especially when some inputs cannot be operated. The K3NR simulates
an input to check the output conditions.
Refer to 6-2 Output test for details.
Hysteresis
The established setting value includes a hysteresis setting to prevent “chattering” of the output when the measured value fluctuates in the vicinity of the setting
values.
Hysteresis is enabled when the measured value is starts to become smaller than
the HH and H setting values and larger than the LL and L setting values.
Refer to Hysteresis, page 78.
Startup Compensation Time
The startup compensation time parameter keeps the measurement operation
from sending an unnecessary output corresponding to instantaneous, fluctuating input from the moment the K3NR is turned ON until the end of the preset period.
Refer to Startup Compensation Time, page 74.
Remote/Local Selection
The K3NR can be operated remotely through a host computer or locally with key
inputs.
Remote Mode: For programming remotely by downloading setup parameters
from a host computer via RS-232C, RS-485, or RS-422.
Local Mode:
Programming is performed with the front panel key input.
Refer to Remote/Local Programming, page 86.
Process Time for Averaging
Measured Value
Setting process time for averaging measured value prevents the display from
fluctuating due to unstable input.
Refer to Process Time for Averaging Measured Value, page 72.
Auto-Zero Time
The input pulse frequency does not drop to zero perfectly due to the estimated
frequency calculation of the K3NR. Therefore, the K3NR has a function to calibrate the frequency to zero forcibly should no input pulse be received for a certain period. The period during which no pulse is received before the K3TR sets
the frequency to zero is called “auto-zero time.”
Refer to page 62.

Passing Time: f6
FUNCTION
Application example
Measures the passing time for a conveyor line.
Distance
Basic Operation
Measures and displays the input pulse frequency of INA in units of seconds.
By selecting an appropriate prescale value, object passing time D in the range
determined by the prescale value will be displayed. Obtain display value D as
follows:
D (sec) = 1/fA x α
fA: INA input frequency (Hz)
α: prescale value of INA
Rotational speed = Input frequency (f) x (1/No. of pulses (N) per 1 cycle)
Circumferential speed = Circumference of roll (πd) x rotational speed
Passing time = Processing length (L)/Circumferential speed
INB input will be ignored.
Passing time is measured in this mode. Therefore, if the K3NR does not receive
any pulses for a certain period, the K3NR estimates passing time using the estimated frequency calculation function and increases the displayed value.

Pulse Counting: f7
FUNCTION
Application example
Counts the number of objects.
Basic Operation
Counts the number of pulses of INA and displays the result. Obtain display value
D as follows:
D (pulse count) = C x α
C: Pulse count of INA
α: Prescale value
Hold Displayed Value
By turning the HOLD input ON, the displayed value can be put on HOLD. While
the HOLD input is ON, the pulse counting operation continues, as does comparative output and BCD output. In this case, using the HOLD input is similar to
checking a lap time with a stopwatch.
Interruption of Pulse Counting
With INB input ON, the pulse counting operation is interrupted and the measured value, comparative outputs, and BCD output are on HOLD. Pulse counting will not begin while INB input is ON.
Clearing Accumulated Value
When the RESET input turns ON, the accumulated value is cleared to zero.
Pulse counting will not start while the RESET input is ON.
The accumulated value will be stored or cleared to zero when the K3NR is turned
off, and depends on the setting of the power failure memory (memo) at option
menu.
Note By connecting comparative output with the RESET input terminal, the K3NR can
be used as a single-mode preset counter.

Maximum Pulse Counting
Speed
Maximum pulse counting speed is the maximum speed at which the K3NR
can count INA input pulses accurately. If comparative output is used as control output, the maximum pulse counting speed can be obtained as follows:
Maximum counting speed (cps) = 1/Delay in comparative outputs (sec)
If comparative output is directly connected to RESET input, the maximum
pulse counting speed can be obtained as follows:
Maximum counting speed (cps) = 1/Delay in comparative outputs (sec) + Response time of RESET input (sec)
Response Time of HOLD or
RESET Input
The response time of the HOLD or RESET input is the time required for the
K3TR to accept HOLD or RESET input after the HOLD or RESET input turns
ON. This is illustrated in the following diagram.

To display rotational speeds, circumferential speeds, or other values based on
input pulse calculations, the rotational speed must be multiplied by a factor input
before the input pulses are measured. This factor is called a prescale value.
Display value = Measured data x Prescaling value
Prescaling values can be set within a range between 0.0001 x 10–9 and 9.9999 x

Calibrates the process value to zero forcibly if no input pulse is received for a
certain period. This period is called auto-zero time.
Refer to the following graph.
Frequency
Auto-zero time
Time
Logically, the input pulse frequency does not drop to zero perfectly due to the
estimated frequency calculation of the K3NR. Therefore, the K3NR has a function to calibrate the frequency to zero forcibly if no input pulse is received for a

Automatic zero time is determined by the following formula.
Auto-zero time = X x 10Y (s) (X: mantissa, Y: exponent)
Note Auto-zero time must be longer than the value obtained by dividing
one by the minimum frequency input of the K3NR. Auto-zero time
must not be less than 0.1 s.
If the operating mode of the K3NR is set to F7 (pulse counting), this parameter
will not be available.

RD4-4, and RD5-1 through RD5-4 in the same way as RD1-1 through
RD1-4.
2. Connect the RUN and OVER signals if they are used as status data.
When the HOLD signal is ON, the measurement operation stops and the process value input effective immediately before the HOLD signal is retained.
When the RESET signal is ON, the maximum and minimum values are set to the
process value.
The OVER signal is ON when the input value is not within the display range.
Timing Charts
Section 7-2
The process value is output when the MAXREQ or MINREQ signal is ON at the
time the output is tested in output test.
Multiple input signals must not turn ON. If multiple input signals turn ON or a
single signal input is combined with another signal input, all output data will be
turned OFF.

Timing Charts
When a REQ signal is input from a Programmable Controller to the K3NR in
RUN or output test, the K3NR outputs a DATA VALID (DSV) signal. In other
cases, the K3NR has All Signals OFF (H) output.

The K3NR in output test has test data output regardless of the type of REQ signal.
Operating Conditions
The RUN signal is turned ON in RUN or output test. The RUN signal is, however,
turned OFF when an error other than overflow results.
Do not input multiple signals, otherwise all output data will be turned OFF.

Items to Be Checked First
First, check the following three items if the K3NR has any problems during operation.
1, 2, 3...
8-2
1. Power Supply
Be sure that power supplied to the K3NR is within the rated voltage range.
2. Wiring
Be sure that the K3NR is wired correctly.
3. Communications Conditions
If the model is a K3NR with the Communications Output Board, be sure that
the baud rate and unit numbers are correct.
After checking and remedying the above items, if the K3NR still has problems
during operation, check the error message.
Display
8-2-1 Flashing
The display will flash in the following cases.
• The input or process value is not within the display range.
If the display flashes the output status will be as follows:
Models with BCD Output Board: The OVER signal will be ON.
Models with Communications Output Board: The OVER or UNDER signal
will be ON and other output signals will be retained.
• The display will flash for three seconds if an attempt is made to change a setting on the K3NR. Set to remote programming to accept key input.
8-2-2 Error Message
The error condition can be checked with the error message.
The K3NR will have the following output statuses when an error message is displayed.
• HH, H, PASS, L, and LL will all be OFF.
• Linear output will be limited to the minimum value.
• The type of BCD output will be All Outputs OFF (H).
• The Unit error response will be returned from the model with a communications
function.

Display
Section 8-2
Notice
When the power is turned ON for the first time after a separately purchased Output Unit is mounted to the K3Nj, the following messages will be displayed.
Follow the procedures below to clear the messages.
chgĆo
Meaning of Message:
This message is displayed when the power is turned ON after an Output Unit is
mounted or replaced.
It is also displayed when there is an error in the internal circuitry.
Remedy:
Press the Mode Key for less than 1 second. The K3Nj should enter RUN mode.
In this case, a malfunction has not occurred.
If chgĆo continues to be displayed, turn the power OFF and ON again. If the
K3Nj still fails to enter RUN mode, repairs are necessary. It is possible that
noise has caused faulty operation.
errĆo
Meaning of Message:
This message will be displayed when the power is turned ON and either an incompatible Output Unit has been mounted on the K3Nj or an Output Unit has
not been mounted on the K3Nj with set value LED display.
It is also displayed when there is an error in the internal circuitry.
Remedy:
Check that the Output Unit is compatible, and if it is not, turn OFF the power and
replace it with a compatible one. If an Output Unit is not mounted on the K3Nj
with set value LED display, turn OFF the power and mount a compatible Unit.
When the power is turned ON again, chgĆo will be displayed. If the Mode Key is
pressed for less than 1 second, the K3Nj should enter RUN mode. In this case,
a malfunction has not occurred.
If errĆo or chgĆo is still displayed, turn the power OFF and ON again. If the
K3Nj still fails to enter RUN mode, repairs are necessary. It is possible that
noise has caused faulty operation.

Estimated Frequency Calculation
If input pulses are suddenly interrupted, the estimated frequency calculation function continuously estimates the
frequency in preparation for the next pulse that may occur. This function ensures improved response to any pulse
occurring within the time period represented by the shaded area of the accompanying graph.
Frequency
Time
Estimated frequency calculation
Estimated frequency calculation graph:
Input pulse
Frequency
Estimated
frequency
calculation
The input frequency cannot be calculated with pulse P0 only. Therefore, the result remains 0. With pulse P1, T1
(from P0 to P1) is measured as one cycle, and the input frequency is calculated from 1/T1. With pulse P2, if T1 is
larger than T2 (if the input frequency increases, i.e. the cycle is shorter), 1/T2 is adopted as the input frequency at
that moment. If no pulse is detected for the T2 period after P2, the new input frequency cannot be known until the
next pulse is detected. The estimated value is 1/T3 if no pulse is detected for period T3. If P3 is detected at that
time, the input frequency then is 1/T3. Therefore the K3NR produces a fast and accurate response as a result of its
estimate. It is better to estimate the input frequency than to keep the frequency, 1/T2, until pulse P3 is actually
detected. With this function, the K3NR can react to sudden changes in the input frequency.
