Drive encoder feedback connectors carry incremental or absolute position data from motor encoders back to servo drives using D-sub 9-pin, M23 12-pin, or proprietary connectors depending on the encoder protocol.
| Pin | Name | Function | Type |

| 1 | VCC | Encoder supply 5V or 8V | PWR |
| 2 | GND | Ground | GND |
| 3 | A+ | Channel A positive | BUS |
| 4 | A- | Channel A negative | BUS |
| 5 | B+ | Channel B positive | BUS |
| 6 | B- | Channel B negative | BUS |
| 7 | Z+ | Index positive | BUS |
| 8 | Z- | Index negative | BUS |
| 9 | DATA+ | EnDat SSI data positive | BUS |
