Parameter Description
Parameter Description
5.16 Communication Function (P.32, P.33, P.36, P.48~P.53, P.153~P.154)
P.32 “Serial communication Baud rate selection”
P.33 “Communication protocol selection”
P.36 “Inverter station number”
P.48 “Data length”
P.49 “STOP bit length”
P.50 “Parity check selection”
P.51 “CR, LF selection”
P.52 “Number of communication retries”
P.53 “Communication check time interval”
P.153 “Communication error handling”
P.154 “Modbus protocol selection”
Reset the inverter after revising the communication parameters.
The SS2-type inverters have two optional communication protocols: Shihlin protocol and Modbus
protocol. Corresponding P.32, P.36, P.52, P.53, and P.153 are applied to both protocols. P.48~P.51 is
only applied to the Shihlin protocol while P.154 is only applied to Modbus protocol.
For continuous communication, please set the following listed parameters correctly, otherwise it
cannot carry out normal continuous communication.
