9.1 RS-485 communication interface (hardware)
The ASDA-A3 series servo drive supports RS-485 serial communication that you can use to
access and change the parameters of the servo system. See the following description of the
wiring:
Note:
1.
The cable length can be up to 100 meters when the servo drive is installed in a quiet environment.
If the transmission speed is over 38,400 bps, a 15-meter cable is recommended to ensure data
transmission accuracy.
2.
The numbers on the above figure represent the pin number of each connector.
3.
Use 12 V
DC
for the power supply.
4.
When using RS-485 communication, you may connect up to 32 servo drives. Install a repeater to
connect more servo drives (the maximum is 127 stations).
5.
Refer to Chapter 3 Wiring for CN3 pin assignment.
