This parameter is used to set the data transfer rate between the host computer and
the inverter. Note: the baud rate must be set to the same for the host computer and the
inverter, otherwise communication can not be achieved. The larger baud rate, the faster
communication speed.

Communication
address of this unit
1 to 247, 0 for broadcast address 1 ☆
Chapter 5 Function parameter
71
When the master is in the write-frame, the communication address of the slave is
set to 0, that is the broadcasting communication address, all slaves on MODBUS will
accept the frame, but the slave does not respond. Note that the slave's address can not
be set to 0.
The communication address of this unit has uniqueness in the communication
network, which is the basis of peer-to-peer communication for the host computer and
the inverter.
F9.03
Communication
response delay
0 to 200ms 5ms ☆
Response delay: it refers to the interval time from the end of the inverter receiving
data to the start of it sending response data to the host machine. If the response delay is
less than the system processing time, then the response delay time is subject to the
system processing time; If the response delay is longer than the system processing
time, after the system finises the data processing, and continues to wait until the
response delay time, and then sends data to the host computer.
F9.04
Communication
timeout fault time
0.0 (invalid) ; 0.1 to 100.0s 0.0 s ☆
Communication time-out parameter is not valid when the function code is set to
0.0s.
When the function code is set to valid, if the interval time between one
communication and the next communication exceeds the communication time-out time,
the system will report communication failure error (E.CE) .
Generally, it is set to invalid. If the parameter can be set to monitor the
communication status in continuous communication system.
