OPERATION
[Example]
Input frequency: 2 Hz
Sampling time: 0.5 sec.
Pulse rate: 3/2
Output pulse width: Duty ratio approx. 50 %
Max. output frequency: 1 kHz
1) The JPR2 counts the number of pulses during the sampling time (period). In the example, 1 count in 0.5 sec. time.
2) Converts the number in the preset rate. In the example, 1 pulse × 3/2 = 1.5 pulses
3) Outputs the converted pulses in the next sampling period.
If certain pulses are not output within the time frame due to a fraction or the max. output frequency limit, they are output in
the following sampling period. In the example, 1 pulse is output in the second period, two pulses are output in the third to
adjust the fraction.
