1) 2-wire RS485
The 2-wire RS485 device on the operation panel and the 4-wire RS485 device on the control circuit terminal
block are intended for data communications between inverters. To use an optional part for the RS48 5 device, it
should be connected to the communication connector (RJ45) on the operation panel. Through the 2-wire RS485
device!and a USB device (optional), the inverter can be linked to a co mputer.
!Here are the parts optionally available for the 2-wire RS485 device.
• Optional USB-to-Serial conversion unit (Model: USB001Z)
Inverter-to-RS485/USB device interconnect cable (Model: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))
RS485/USB device-to-computer interconnect cable. Use a commercially available USB1.1 or 2.0 cable. (Type:
A-B, Cablelength: 0.25~1.5m)
• Optional LED Remote Keypad (Model: RKP002Z)
Communication cable (Model:CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))
• Optional LCD Remote Keypad (Model: RKP004Z)
LCD special cable (Model:CAB0071 (1m), CAB0073 (3m), CAB0075 (5m), CAB00 710 (10m))
Note: Do not connect the cable (CAB0011, 0013 or 0015) from the communication device t o the optional LCD
Remote Keypad. Or the inverter or the optinol LCD Remote Keypad could be dama ged.

■ Communication parameters (2-wire RS485)
These parameters allow you to change the communication speed, parity check set ting, inverter number,
communication error trip timer setting, etc. from the operation panel or an e xternal control device.
