These series inverter supply RS485 communication port and adopt MODBUS startded communication protocol. Therefore,
the inverter can be set as a slave to communicate with the marter ( such as PLC and PC ) which has the same communicatin
port and protocol ; also, user can use a inverter as the master to communicate with several inverters produced
by
our
company via RS485 port to realize multi- machine linkage
.
Besides, you can connect the RS485 port to remote keyboard to
realize remote operation .
This inverter support MODBUS-RTU, the following is the particular instruction for the inverter
’
s communication protocol .

The inverter can be used as both master and slave in RS485 net. If it is used as a master, it can control other inverters made
by
our company to realize multi - machine linkage . If it is used as a slave, PC or PLC can be set as a master to control it. The
concrete communication modes are shown below:
(1) (1) The inverter is a slave in the network. It communicates in ‘ point to point
’
mode. The inverter will not response
to the command sent
by
the master via broadcast address.
