7.2.2 Functions Used and Restrictions
The maximum counting speed and pulse output frequency of the high-speed counter vary according to
the number of channels to be used or the combination of used functions. Use the chart below as a guide.
Simplified chart - Maximum counting speed of High-speed counter (For L14 and L30 types)
A: Available
Combination of high-speed counter
Max. counting speed (Frequency kHz)
Combination with pulse output function (trapezoidal control)
CH0 CH1 CH2 CH3 CH0 CH2
Single-
A 20 19 20 14 20 6
Note) The maximum counting speed may be lower than the above-mentioned values when the target value match
ON/OFF instruction (F166/F167) or an interrupt program is executed simultaneously.
