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.
