Counting mode
The high-speed counter as the following five counting modes.
■
Adding counter (single-phase high-speed counter)
The adding counter counts up with the rise in pulse input.
■
Up/down selection reversible counter (single-phase high-speed counter)
Up/down selection reversible counter can switch between addition and subtraction by pulse input with the up/down selection
input. When the up/down selection input is on, the counter counts up with the rise in pulse input. When the up/down selection
input is off, the counter counts down with the rise in pulse input.
■
Dual-pulse reversible counter (single-phase high-speed counter)
This counter switches between the up count and the down count with pulse input (up) and pulse input (down). When a pulse is
input to pulse input (up), the counter counts up with the rise in pulse input. When a pulse is input to pulse input (down), the
counter counts down with the rise in pulse input.
■
2-edge count (two-phase high-speed counter)
This counter counts by the phase difference between the A-phase and B-phase pulse input. When the A-phase precedes the B-
phase, the counter counts up with the rise and fall of the B-phase. When the B-phase precedes the A-phase, the counter counts
down with the rise and fall of the B-phase.
■
4-edge count (two-phase high-speed counter)
This counter counts by the phase difference between the A-phase and B-phase pulse input. When the A-phase precedes the B-
phase, the counter counts up with the rise and fall of the A-phase and the B-phase. When the B-phase precedes the A-phase,
the counter counts down with the rise and fall of the A-phase and the B-phase.
