8.1 Pulse Input Modes and Counting Methods
This section describes the pulse input modes and the counting methods.
8.1.1 Types of pulse input modes
The following six pulse input modes are prepared: 1-phase pulse input (1 multiple/2 multiples), CW/CCW pulse input,
and 2-phase pulse input (1 multiple/2 multiples/4 multiples).
(1) Pulse input modes and count timing
Pulse input mode Count timing
1-phase multiple of 1
At up count
Counts on the rising edge () of A.
B and CH Down count command (Y3, YB) are off.
At down count
Counts on the falling edge () of A.
B or CH Down count command (Y3, YB) is on.
1-phase multiple of 2
At up count
Counts on the rising edge () and the falling edge ()
of A.
B and CH Down count command (Y3, YB) are off.
At down count
Counts on the rising edge () and the falling edge ()
of A.
B or CH Down count command (Y3, YB) is on.
CW/CCW
At up count
Counts on the rising edge () of A.
B is off.
At down count
A is off.
Counts on the rising edge () of B.
2-phase multiple of 1
At up count Counts on the rising edge () of A while B is off.
At down count Counts on the falling edge () of A while B is off.
