Chapter6 Communication
6.1
Communication Hardware Interface
Bonmet SA Series servo drives have three
communication modes
: RS-232, RS-485 and CANOpen. All aspects of
control, operation and monitoring as well as programming of the controller can be achieved through
communication. However, only one communication mode can be used at a time. Users can select the desired
communication mode by parameter Pn184.
Please refer to the following sections for connections and limitations.
6.2
ModBus Communication Protocol
When using RS-232/485 serial communication interface, each SA series AC servo drive has a pre-assigned
communication address specified by parameter Pn185. The computer then
controls each AC servo drive according to its communication address. SA series AC servo drives can be set up to
communicate on a MODBUS networks using on RTU (Remote Terminal Unit)mode.
6.1.1Code Description:
When controllers are setup to communicate on a Modbus network using RTU(Remote Terminal Unit) mode, each
