3.10.2 Maximum counting speed of counter

The maximum counting speed of the counter is determined by the scan time, and the counter can count only when the ON/OFF period of the input condition is longer than the scan time.

	Maximum counting speed Cmax	n		1	[times/s]	n: Duty (%)
		100		ts
						ts: Scan time [s]

REMARKS

The duty n is a percent (%) ratio of ON/OFF period to (ON + OFF period) of the count input signal.
