●
When the communication parameters are revised, please reset the inverter.
●
The SF-type inverters have two communication protocols to selection, Shihlin protocol and
Modbus protocol. If the communication expansion board is selected, the corresponding
communication protocol is provided. P.32, P.36, P.52, P.53, and P.153 are applied to both of the
protocols. P.48~P.51 is only applied to the Shihlin protocol
，
and P.154 is only applied to Modbus
protocol.
