3.5Serial Communication Connector CN3

3.5.1 CN3 Terminal Layout and Identification

The servo drive can be connected to a PC or controller via a serial communication connector. The users can operate the servo drive through PC software supplied by Delta (contact to the dealer/distributor).

The communication connector/port of Delta servo drive can provide two common serial communication interfaces: RS-232, and RS-485 connection. RS-232 is mostly be used but is somewhat limited. The maximum cable length for an RS-232 connection is 15 meters (50 feet). Using RS-485 interface can allow longer distance for transmission and support multiple drives to be connected simultaneously.
