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) = T 1 • 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 fac- tor. This factor is called the prescaling value. Example: Proximity Sensor K3NR 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). Comparison output patterns can be selected from the standard, level, or zone output depending on the application. Refer to Comparative Output Patterns, page 80. 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. Refer to the Communications Manual. 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.

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 con- nected, 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 “chatter- ing” 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, fluctuat- ing input from the moment the K3NR is turned ON until the end of the preset peri- od. 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. 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 cali- brate the frequency to zero forcibly should no input pulse be received for a cer- tain 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.

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 esti- mated frequency calculation function and increases the displayed value. Mode Unit of display value Prescale value Passing time sec L/(πd/N) N = No. of pulses per 1 cycle from input A πd = Circumferential length (m) per 1 cycle L = Processing length (m) Note The K3NR can display the hour, minute, and second. Refer to page 65 for de- tails. Example: Displaying passing time (sec) using a rotary encoder with 100 output pulses per revolution. Circumference of rotary encoder = 0.125 m Process length = 5 m Prescaling value (α) = 5/(0.125/100) = 4000 = 4.000 x 103 Prescale value = X x 10Y (X: mantissa, Y: exponent) X (mantissa) of input A = 4.000 Y (exponent) of input A = 3 Refer to 4-2 Setting Mode.

When the HOLD input is turned ON, measurement stops and the input mea- sured just before the HOLD input turned ON is held. While the HOLD input is ON, the K3NR holds display output, comparative output, and BCD output. When the comparative output from the Output Board is connected to the HOLD input terminal, the value measured immediately after the occurrence of an error can be obtained.

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 compar- ative 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 mea- sured value, comparative outputs, and BCD output are on HOLD. Pulse count- ing 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 (����) at option menu. Note By connecting comparative output with the RESET input terminal, the K3NR can be used as a single-mode preset counter. FUNCTION Pulse Counting: �� Section 3-7

Auto Zero Time of Input A Y (Exponent) Auto Zero Time of Input B X (Mantissa) Auto Zero Time of Input B Y (Exponent) 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 func- tion to calibrate the frequency to zero forcibly if no input pulse is received for a certain period. 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.
