CNT-3208M-PE
Single-phase Input
During single-phase input, input of an UP pulse results in counting up while input of a DOWN pulse
results in counting down. If UP and DOWN pulses are simultaneously generated or both pulses change
to LOW, normal counting does not take place.
Figure 4.2. Example counting during single-phase input
Single-phase Input with Gate Control Attached
The counter can be started/stopped according to a gate control signal input along with a series of single-
phase pulses. A clear signal clears the counter value to zero.

* Count operation for incremental counting in the CW direction. When decremental counting in
the CW direction is set, the board performs decremental counting at the rising edges of positive
pulse and incremental counting at the rising edges of negative pulses.

* Count operation for incremental counting in the CW direction.
When decremental counting in the CW direction is set, the board performs decremental
counting at the rising edges of the single-phase pulse train (phase-A/UP) while the gate control
signal (phase-B/DOWN) goes high and stops counting while the gate control signal goes low.
