Counter
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.
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.
3.
Minimum signal width: 16.7 ms (when maximum counting speed = 30 Hz)
100 µs (when maximum counting speed = 5 kHz)
4.
The meaning of the H and L symbols in the tables is explained below.
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
UP/DOWN D Command Input Mode
must be at least 1/2 the minimum signal width. (See note 2.)
must be at least 1/2 the minimum signal width. (See note 2.)
UP/DOWN E Individual Input Mode
UP/DOWN F Quadrature Input Mode
must be at least 1/2 the minimum signal width. (See note 2.)
