The CFW-09 can be controlled, programmed and monitored via an RS-232
Serial Interface. The communication protocol is based on question/response
telegramsaccordingtoISO1745andISO 646standards,withASCII characters
exchanged between the inverter and a master (network controller, which can
be a PLC, PC, etc.). The maximum transfer rate is 9600 bps. The RS-232
serialinterface is not galvanically isolated from the 0 V reference of the inver-
ter electronics, therefore the maximum recommended serial cable length is
10 m (30 ft).
To implement the serial communication, an RS-232 SERIAL INTERFACE
module has to be added to the CFW-09. This module is installed in place of
the Keypad, making the RS-232 connection (RJ11 connector) available. If the
useof the HMI is alsorequired, the RS-232modulealso providesits connection.
