SJ300 Inverter

Appendix B

The network master sends a frame to initiate 
communications with a slave, as shown in the 
figure to the right. After the set waiting time 
(per parameter C078, the inverter responds.

The following table lists the commands, single-character codes sent to a particular device on 
the network.

NOTE: Use of command 08 – set inverter parameters to default values first requires setting the 
initialization mode parameter B084 to 01 (initializes parameters only) or 02 (initializes param-
eters and clears the trip history).
