Question

What is the relationship between the Counter's maximum counting speed and minimum signal width?

Answer



Example: 30 Hz

Indicates 30 pulses per second (1,000 ms).

Therefore,

1000 ÷ 30 = Approx. 33.3 ms

33 ÷ 2 = 16.7 ms (minimum ON signal width and OFF signal width)

Description


ON/OFF Ratio

Ratio of the count input signal's ON time to OFF time.

(The Counter's maximum counting speed is specified at an ON/OFF ratio of 1:1.)
