1.1  Pulse Input Modes and Counting Methods
For the 1-phase pulse input and counting up pulses, check that the B phase pulse input and CH1 Down count 
command (Y3) are off before performing the A phase pulse input. If at least one of the B phase pulse input 
and CH1 Down count command (Y3) is on, pulses are counted down in the A phase pulse input.
2-phase multiple of 1 For counting up Counts on the rising edge () of A while B is off.
For counting down Counts on the falling edge () of A while B is off.
2-phase multiple of 2 For counting up Counts on the rising edge () of A while B is off.
Counts on the falling edge () of A while B is on.
For counting down Counts on the rising edge () of A while B is on.
Counts on the falling edge () of A while B is off.
2-phase multiple of 4 For counting up Counts on the rising edge () of A while B is off.
Counts on the falling edge () of A while B is on.
Counts on the rising edge () of B while A is on.
Counts on the falling edge () of B while A is off.
For counting down Counts on the rising edge () of A while B is on.
Counts on the falling edge () of A while B is off.
Counts on the rising edge () of B while A is off.
Counts on the falling edge () of B while A is on.
