V5 series inverter

7-2-2. Communication protocol modes

The inverter can be master and slave in RS485 network. If it is master, it can control other inverters
made by our company to realize multi-machine linkage.If it is slave, PC or PLC (master) can control it.
The concrete communication modes are shown below:
(1) The inverter is slave, master-slave point-to-point mode. The slave devices will not response when
master sends requires by broadcast address.
(2) The inverter is master. The slave devices will not response when master sends requires by broadcast
address.
(3) Users can set the inverter address, baud rate and data format via the keypad or serial port.
(4) The slave report the current fault information in the latest response frame.

7-2-3. Communication port

RS485 port is asynchronous serial, half-duplex transmission. Default data format: 1 start bit, 8 data bits,
1 stop bit.
Default baud rate 19200bps, the communication parameters please refer to P3.09~P3.12.
