Chapter 9 Communications
9.1 RS-485 & RS-232 Communication Hardware Interface
The ASDA-A2 series servo drives support RS-485 and RS-232 serial communication. All
aspects of control, operation and monitoring as well as programming of the controller can be
achieved via communication. However, only one communication mode can be used at a time.
Users can select the desired communication mode via parameter P3-05.
Please refer to the following sections for connections and limitations.
RS-232
Configuration
NOTE
1) Recommended maximum cable length is 15m (50ft.). Please note, RFI / EME noise should be
kept to a minimum, communication cable should kept apart from high voltage wires. If a
transmission speed of 38400 bps or greater is required, the maximum length of the
communication cable is 3m (9.84ft.) which will ensure the correct and desired baud rate.
2) The number shown in the pervious figure indicates the terminal number of each connector.
