26 / 43 page ![]() C-112 Multifunction Preset Counter H7CX (Counter Function) Input Modes and Present Value Note: 1. If the configuration selection is set to dual counter, CP1 and CP2 input will operate in the same way as the count input (CP1) of UP (increment) mode. 2. a must be greater than the minimum signal width and b must be at least 1/2 the minimum signal width. If they are less, a count error of ±1 may occur. Minimum signal width: 16.7 ms (when maximum counting speed = 30 Hz) 100 µs (when maximum counting speed = 5 kHz) 3. The meaning of the H and L symbols in the tables is ex- plained below.
