3.6 Wiring of CN3 Connector
3.6.1 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. Both can be set via parameter P3-05. 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.

NOTE
1) Please refer to Chapter 9, page 2 for the wiring of RS-485.
2) Two kinds of communication wire of IEEE1394 are commercially available. One of the internal
ground terminals (Pin 1) will short circuit with the shielding and will damage the drive. Do not
connect GND to the shielding.
