3.5.3 Connection to RS-485 connector (only the inverter with RS-485
communication function)
(1) When connecting the parameter unit (FR-PU04)
Use the optional FR-CB2 .
(2) RS-485 communication
Use the RS-485 connector to perform communication operation from a
personal computer etc. By connecting the RS-485 connector to a computer
such as a personal computer, Factory Automation or other computer, by the
communication cable, you can operate/monitor the inverter and read/write the
parameter values using user programs. For further details, refer to the
instruction manual (detailed).
•
Standard with which RS-485 connector conforms: EIA Standard RS-485
•
Transmission format : Multi-drop link
•
Communication speed: Maximum 19200 bps
•
Overall extension : 500m (1640.42feet)
CAUTION
Do not plug the connector to a computer LAN board, fax modem socket,
telephone modular connector etc. As they are different in electrical
specifications, the inverter may be damaged.
