Functional Details 61
F4.01 Local address
Setting range: 0 ~ 30
The local address set for communication of this inverter is only effective when this
inverter is used as the slave machine. During communication, this inverter only
sends back response frame for data frames corresponding to the local address, and
receives command.
With the SUNFAR self-defined protocol, the address 31 is the broadcasting address,
and 0 represents the broadcasting address in the case of MODBUS communication.
For broadcasting data, the slave machine executes command but does not give
feedback of corresponding data (see the appendix of communication protocol).
F4.02 Local response delay
Setting range: 0 ~ 1000 ms
The waiting time till sending response data frame after the local inverter has
correctly received information code of the upper computer.
F4.03 Setting of communication auxiliary function Setting range: 0000 ~ 0011
LED UNITS: Main and slave inverter setting
0: This inverter is the main inverter 1: This inverter is a slave inverter
When multiple inverters requires linkage synchronous control, one of inverters
should be set as the main inverter.
LED Tens: Action selection after communication failure
0: Shutdown
1: Maintaining current status
LED Hundreds: Data return selection
0: Normal return of data
1: Do not return data
LED Kilobit: Reserve
