Parameter Description
Parameters
75
●
When the communication parameters are revised, please reset the inverter. The SF-GT
inverters have two communication protocols for selection, namely, Shihlin protocol and
Modbus protocol. Parameter P.32, P.36, P.52, P.55 and P.153 are suitable for both
protocols. P.48~P.51 is only suitable for the Shihlin protocol, while P.154 is only suitable for
the Modbus protocol. Please refer to communication protocols for more details.
