Overview
Taiwanese servo drives meant for servo motors from the same company. They can have both high and low resolution incremental encoders that both use an RS-485 type serial protocol.
Model Numbers
- Page 18 (1-3 in the PDF) gives the servo drive model number scheme.

Replacement Parts
RS-232 Cable
ASD-CARS0003
The cable has an IEEE 1394 plug for CN3 on the servo drive, and a female DE9 plug with male #4-40 thumbscrews for RS-232. The RS-232 DE9 pinout is designed to interface with a DTE (PC) directly without a null modem adapter.
Pin mapping:
| IEEE 1394 Pin | DE9 Pin | Function |
|---|---|---|
| 1 | 5 | GND |
| 2 | 2 | RS-232 TX (drive → PC) |
| 3 | ||
| 4 | 3 | RS-232 RX (drive ← PC) |
| 5 | ||
