Example Length of processing stage F1: Displays rotation (rpm) or circumferential speed for one input. F2 to F5: Displays the calculation result for two rotation (rpm) speeds. F6: Function name The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is to count the ON/OFF time (T) for input sensor or other device inputs using the internal system clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and displayed as the rotation (rpm) speed. Function No. Rpm/circumferential speed f1 Absolute ratio f2 Error ratio f3 Rotational difference f4 Flow rate ratio f5 Passing time f6 Displays the passing time calculated from the circumferential speed and the length of the processing stage for one input. Input sensor or other input pulse ON/OFF time (T) = Function Operation Measures frequency for input A and displays the rotation (rpm) or circumferential speed proportional to the input frequency. Rotation speed Frequency (of input pulse) Circumferenti al speed Instantaneous flowrate Frequency (f) = 1 T • Rotation speed (rpm) = f × 60 • Circumferential speed = Roll circumference × Rotation speed (rpm) • Passing time= Length of processing stage Circumferential speed These calculations are automatically made internally and displayed whenever any input pulse is received.

Calculation Passing time Display unit Prescale value (α) s L/(πd/N) N = Pulses per rotation πd = Circumferential length per rotation (m) L = Length of process (m) 8 Rotary Pulse Indicator K3HB-R Distance H PASS L Warning output ■ What Is Prescaling? To make calculations using the input pulse to display rotation (rpm) or circumferential speed, the number of pulses per rotation or the length of the circumference must be multiplied by a certain coefficient. This coefficient is called the prescale value. K3HB-R Proximity sensor Rotation speed (rpm) = f × 60 × a f: Input pulse frequency (No. of pulses per second) a: Prescale value If there are 5 pulses per rotation, then a = 1/5 (= 0.2 = 2 × 10 ) and an accurate rotation speed (rpm) can be calculated. -1 The actual setting is X = 2.0000 (mantissa) and Y = 10-1 (exponent). ■ What Is the Auto-zero Function? (Set this function before using the Digital Indicator.) If a function f1 to f6 is set, the frequency can be force-set to zero if there is no input pulse for a set period. This period is called the autozero time. Set the auto-zero time to slightly longer than the longest input pulse interval. (The display will not easily return to zero if the auto-zero time is too long or left at the default setting.) Time Unit Settings Setting Meaning scal Prescale value menu setting min Minute display h.mm.ss h.mm.ss display mm.ss.d mm.ss.d display (d = tenths of a second) Note: Time unit can be set only when passing time (F6) is selected. Input Type Setting NO: Voltage pulse high NC: Voltage pulse low No-contact or voltage pulse input 00 01 Contact 10 11 Note: Set to 10 or 11 when there is a large variation in the display. The largest measurement range is 30 Hz.
