8.1. Communication interface and wiring
The SDE servo drive equips RS-485 and plug-play USB serial communication functions. These
functions could be used to perform servo operation, parameter changing, monitor function, etc.
However, the RS-485 communication and USB could not be used in synchronization. The wirings are
demonstrated below.
RS-485
(1) Outline：
Up to 32 devices of servo drives from stations 1 to 32 could be operated on the same bus.
(2) Wiring diagram：
Recommendation: To connect ground terminal of RS-485/RS-232 converter and GND (pin1,pin2) of
CN3 could reduce communication failure if necessary.
