Commnuication wiring and setup
(1)
Turn off power supply and connect communication lines of the controller to the inverter (RJ45).
(2)
Turn power on.
(3)
Set the required communication parameters (09-00) via the keypad.
(4)
Turn off power to the inverter and wait until keypad is completely off.
(5)
Turn power on again.
(6)
Start communication between controller and inverter.
Modbus (485) communication architecture
(1)
Modbus communication configuration uses a master controller (PC, PLC), communicating to a
maximum of 31 inverters.
(2)
The master controller is directly connected to the inverter via the RS-485 interface. If the master
controller has a RS-232, a converter must be installed to convert signals to RS-485 to connect
the master controller to the inverter.
A maximum 31 inverters can be connected to a network, following the Modbus communication
standard. Communication parameters as follows:
Inverter station addresses(09-00)
Setting range is 1-31.
RS-485 Communication baud rate setting(09-02)
09-02= 2:4800 bps (bit/second)
09-02= 3:9600 bps
09-02= 4:19200 bps
09-02= 5:38400 bps
Stop bit selection(09-03, 09-04)
09-03= 0:1 stop bit
09-03= 1:2 stop bits
09-04= 0:No parity.
09-04= 1:even parity
09-04= 2:odd parity.
