General Operation Notes
- Commands execute on write operation
- Data value is usually irrelevant (except servo ON/OFF)
- For SVO:
- 0 = Servo OFF
- non-zero = Servo ON [yaskawa-ns...indexer-g3 | Word]
Communication Setup
Must be configured externally (NOT by driver):
- Parameter 800H → Interface type
0 = RS422
1 = RS232
2 = RS485 - Parameter 801H → Baud rate
0 = 9600
1 = 19200
2 = 38400 [yaskawa-ns...indexer-g3 | Word]
Data Format Behavior
- ALM / ALMH / ERR → ASCII (packed into 4 bytes)
- Example: P‑OT → hex 502D4F54 [yaskawa-ns...indexer-g3 | Word]
- Bit-based returns: IN1 / IN2 / OUT1 / OUT2 / MON6
Example: value 5 → binary 101 [yaskawa-ns...indexer-g3 | Word] - Some IDs return hex values: MTSIZE, TYPE, VER, etc. [yaskawa-ns...indexer-g3 | Word]
POST Function (Program Table)
| Function | G3 Value | Description |
|---|---|---|
| None | 0 | No action |
| Relative | 1 | Relative move |
| Absolute | 2 | Absolute move |
| STOP | 3 | Stop |
| Jog Forward | 4 | Continuous forward |
| Jog Reverse | 5 | Continuous reverse |
[yaskawa-ns...indexer-g3 | Word]
POST Tag Behavior
PTRF → Function type
PTRV → Value (position / jog / stop)
PTWF → Write function type
PTWV → Write position value
PTWS → Execute selected table position [yaskawa-ns...indexer-g3 | Word]
Additional Notes
- Some functions require pre-configured index values
- IN2TEST uses only lower 8 bits
- OUT2TEST uses only lower 6 bits [yaskawa-ns...indexer-g3 | Word]
