Handling of the RS-485 connector
1.7.2 Wiring of RS-485 communication
Use the RS-485 connector to perform communication operation from a personal
computer etc.
When the RS-485 connector is connected with a personal, FA or other computer
by a communication cable, a user program can run and monitor the inverter or
read and write to the parameters. For parameter setting, refer to page 130.
•Conforming standard: EIA-485 (RS-485)
•Transmission format: Multidrop link system
•Communication speed: Max. 19200bps
•Overall extension: 500m
Refer to page 130 for the setting related to RS-485 communication operation.
<System configuration examples>
(1) Connection of a computer to the inverter (1:1 connection)
Computer-inverter connection cable
Refer to the following for the cable (RS-232C
⇔RS-485 converter) for connection of
the computer having the RS-232C interface with the inverter.
Example of product available on the market (as of April, 2004)
*The converter cable cannot connect two or more inverters (the computer and
inverter are connected on a 1:1 basis). Since the product is packed with the RS-
232C cable and RS-485 cable (10BASE-T + RJ-45 connector), the cable and
connector need not be prepared separately.
