Understanding Pulse Input Method and Counting Method
Type of Pulse Input Method ,
Pulse Input Method | Count Timing | ||
1-phase 1-multiple | Counting | A module counts at the rising edges of A. B is off. | |
Counting Down | 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.
