• Function
2-wire RS485 communication is built-in as standard.
Connect with the host to create a network for transmitting data between multiple inverters. A computer
link function is available.
<Computer-linking functions>
The following functions are enabled by data communication between the computer and inverter
(1) Monitoring inverter status (such as the output frequency, current, and voltage)
(2) Sending RUN, STOP and other control commands to the inverter
(3) Reading, editing and writing inverter parameter settings
Timer function
Broadcast communication function
2-wire RS485 communication option is as follows.
(1) USB communication exchange unit (Type: USB001Z)
Cable for communication between the inverter and the unit (Type: CAB0011 (1m), CAB0013 (3m),
CAB0015 (5m))
Cable for communication between the unit and computer: Use a commercially available USB 1.1 or 2.0
cable. (Type: A-B, Cable length: 0.25 to 1.5 m)
(2) Parameter writer (Type: RKP002Z)
Communication cable (Type: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))
(3) Extension panel (Type: RKP007Z)
Communication cable (Type: CAB0071 (1m), CAB0073 (3m), CAB0075 (5m))
However, when using a 5m cable, the core must be inserted.
Core type: ESD-SR-120 (Manufacturer: NEC Tokin Corp.)

... Function used to detect cable interruptions during communication.
When data is not sent even once to the inverter during a user-
defined period of time, an inverter trip (  is displayed on
the panel) or an output terminal alarm can be output.
... Function used to send a command (data write) to multiple
inverters with a single communication.
