As shown in figure 8.17, two types of blank covers are available to be used, in
the inverter or in the frame, when the keypad is not in place.

The CFW-09 can be controlled, programmed and monitored via an RS-232
Serial Interface. The communication protocol is based on question/response
telegrams according to ISO 1745 and ISO 646 standards, 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
serial interface 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
use of the HMI is also required, the RS-232 module also provides its connection.
