Multifunction Counter H7BX 13
■ Input Modes and Present Value
UP (Increment) Mode DOWN (Decrement) Mode
CP1: Count input; CP2: Prohibit input
must be greater than the minimum signal width. (See note 2.)
CP1: Count input; CP2: Prohibit input
must be greater than the minimum signal width. (See note 2.)
CP1: Prohibit input; CP2: Count input
must be greater than the minimum signal width. (See note 2.)
CP1: Prohibit input; CP2: Present value
must be greater than the minimum signal width. (See note 2.)
UP/DOWN A: Command Input Mode UP/DOWN B: Individual Input Mode
must be greater than the minimum signal width. (See note 2.)
UP/DOWN C: Quadrature Input Mode Note 1. If the configuration is set to dual counter, CP1 and CP2 inputs will operate
in the same way as the count input (CP1) of UP (increment) mode.
2. must be greater than the minimum signal width and 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 explained below.
must be at least 1/2 the minimum signal width. (See note 2.)
