A module counts at the falling edges of A.

B is on.

1-phase

2-multiple

Counting

A module counts at the rising and falling edges of A.

B is off.

Counting Down

A module counts at the rising and falling edges of A.

B is on.

CW/CCW

Counting

A module counts at the rising edges of A.

B is off.

Counting Down

A is off.

A module counts at the rising edges of B.

2-phase

1-multiple

Counting

When B is off, a module counts at the rising edges of A.

Counting Down

When B is off, a module counts at the falling edges of A.

2-phase

2-multiple

Counting

When B is off, a module counts at the rising edges of A.

When B is on, a module counts at the falling edges of A.

Counting Down

When B is on, a module counts at the rising edges of A.

When B is off, a module counts at the falling edges of A.

2-phase

4-multiple

Counting

 

 

When B is off, a module counts at the rising edges of A.

When B is on, a module counts at the falling edges of A.

When A is on, a module counts at the rising edges of B.

When A is off, a module counts at the falling edges of B.

Counting Down

 

 

When B is on, a module counts at the rising edges of A.

When B is off, a module counts at the falling edges of A.

When A is off, a module counts at the rising edges of B.

When A is on, a module counted at the falling edges of B.

 

 

1-phase Pulse Input

 

1-multiple or 2-multiple can be selected. The relation between Phase A and counting down is as follows.

 

 

 

 

CW/CCW Pulse Input

 

If there is pulse input in Phase A, the module counts. If there is pulse input in Phase B, the module counts down. The relation between Phase A and Phase B is as follows.

 

 

 

 

2-phase Pulse Input

 

1-multiple or 2-multiple or 4-multiple can be selected. It is decided whether the module counter or counts down by the difference between Phase A and Phase B. The relation between Phase A and Phase B is follows.
