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 and Inverter-to-inverter communication function are 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
< Inverter-to-inverter communication function >
This function allows you to set up a network that makes it possible to carry out proportional operation of
multiple inverters (without using a computer).
● Timer function …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 (
err5 is displayed on the
panel) or an output terminal alarm(“
t” is displayed) can be output.
● Broadcast communication function …Function used to send a command (data write) to multiple
inverters with a single communication.
● Peer-to-peer communication …Refers to the function that enables the master inverter to send the
data selected with a parameter to all slave inverters on the same
network. This function allows you to set up a network that makes
it possible to carry out synchronized operation or proportional
operation (setting of point frequencies) in an abbreviated manner.
● Communication protocol …Toshiba inverter protocol and Modbus RTU protocol are supported
● 2-wire RS485 communication options are as follows.
(1) USB communication conversion 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
cables. (Type: A-B, Cable length: 0.25 to 1.5m)
(2) Parameter writer (Type: RKP002Z)
Communication cable (Type: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))
(3) Parameter writer (Type: PWU003Z)
RJ45 cable (1m) is attached.
(4) Extension panel (Type: RKP007Z)
Communication cable (Type: CAB0071 (1m), CAB0073 (3m), CAB0075 (5m))
Note1) In case of using above options, set the parameter
f805=0.00
