AC Servo : AD Series : Detail of AC Servo Driver with PLC function : Example of Applications and sample program
Case: Multistage Positioning (Input Terminal Conditions)
(1) Case description
When X(11) = 1 upon homing, the servomotor moves to the following position depending on the status of the X(00) to X(03) terminals:
| Input terminal | Target position | ||||
|---|---|---|---|---|---|
| X(03) | X(02) | X(01) | X(00) | Data | |
| 0 | 0 | 0 | 0 | 0 | P(00) |
| 0 | 0 | 0 | 1 | 1 | P(01) |
| 0 | 0 | 1 | 1 | 3 | P(02) |
| 0 | 1 | 1 | 0 | 6 | P(03) |
| 1 | 1 | 0 | 1 | 13 | P(04) |
| 1 | 1 | 1 | 1 | 15 | P(05) |
| Other | P(06) | ||||

(5) Operation and program descriptions
| (1) | Homing is achieved. |
|---|---|
| (2) | The program waits until X(11) turns ON. The bits are masked to prevent the X(11) to X(04) terminals from being affected. |
| (3)(4) | Since X(00) to X(3) = OFF, the servomotor moves to the P(00) position. |
| (11) | The program returns to Step (2) above. |
| (2)’ | The program waits until X(11) turns ON. |
| (5)(6) | Since X(00) = ON and X(01) to X(03) = OFF, the servomotor moves to the P(01) position. |
| (11)' | The program returns to Step (2) above. |
| (2)’’ | The program waits until X(11) turns ON. |
| (7)(8) | Since X(00) = ON, X(01) = ON, and X(02) to X(3) = OFF, the servomotor moves to the P(02) position. |
| (11)'' | The program returns to Step (2) above. |
| (2)’’’ | The program waits until X(11) turns ON. |
| (9)(10) | Since X(00) = OFF and X(01) to X(3) = ON, the servomotor moves to the P(06) position. |
| (11)’’’ | The program waits until X(11) turns ON. |
| (2)’’’’ | The program waits until X(11) turns ON. |
