Parameter
4.17 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 communication data format”
● When the communication parameters are revised, please reset the inverter.
● The SE2-type inverters have two communication protocols to select, 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 the Modbus protocol.
● Continuous communication, please make the following listed parameters set correctly, otherwise it
will not carry out normal continuous communication.
