1.1 Pulse Input Modes and Counting Methods
This section describes the pulse input modes and the counting methods.
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).
Pulse input modes and count timing
Pulse input mode Count timing
1-phase multiple of 1 For counting up Counts on the rising edge () of A.
B and CH1 Down count command (Y3) are off.
For counting down Counts on the falling edge () of A.
B or CH1 Down count command (Y3) is on.
1-phase multiple of 2 For counting up Counts on the rising edge () and the falling edge
() of A.
B and CH1 Down count command (Y3) are off.
For counting down Counts on the rising edge () and the falling edge
() of A.
