EXAMPLES FOR USING DIVISOR PARAMETER
ENDA ETS1410 Pulse Input Tachometer divides the number pulses in one minute by the calibration
value and then, the result is displayed. Calibration value may be selected between 1 and 999. This
feature is used for precise revolution speed, line speed or sudden flow speed measurements.
Calibration value is calculated as explained below:
CAL(divisor value) =
Desired value on the display
Number of pulses per minute
Assume that a
having a circumference of 25cm rotates at a speed of 3 revolutions/minutes.
And the line speed of a band moving on the cylinder is going to be calculated in the unit of cm/minute.
And, a 50 pulse/revolution encoder is used for measuring the revolution speed of the
.
Dividing value is calculated as below;
cylinder
cylinder
Desired value on the display: 3 revolution/minute x 25 cm/revolution = 75 cm/minute
Number of pulses per one minute: 3
x 50 pulse/
= 150 pulse/minute
Then; CAL(divisor value) = = 2
revolution/minute

Error messages:
Input frequency is too low or there is no signal.
Input frequency is too high.
Measured value is greater than 9999.
