C200H-CT002, the pulse width of input Z must be 10 or greater, and the re-
turn frequency, allowing for software processing time, must be 10 kcps or
less.
With separate up and down pulse inputs, the counter value is incremented or
decremented on the rising edge of the appropriate input. Here, sensors could
replace the encoders to provide inputs A and B.
In the linear or circular operating modes, the counter can be reset by connecting
input Z to a sensor or switch.

With pulse and direction inputs, the counter value is incremented or decre-
mented on the rising edge of the pulse input. If the direction input is OFF, the
counter value is incremented; if the direction input is ON, the counter value is
decremented. The direction input should be switched between ON and OFF
only when the pulse input is OFF.
In the linear or circular operating modes, the counter can be reset by connecting
input Z to a sensor or switch.
