3.5 Wiring of CN3 Connector

Layout of CN3 Connector
The servo drive connects to the personal computer via communication connector. The
user can operate the servo drive via MODBUS, PLC or HMI. There are two common
communication interfaces, RS-232 and RS-485. Among them, RS-232 is more common.
Its communication distance is about 15 meter. If the user selects RS-485, its transmission
distance is longer and supports more than one servo drives for connection.
