SJ300 Inverter
Appendix B
B–11
Command – 05
The 05 command reads the inverter’s trip history. 
The frame format of command 05 follows the 
diagrams and specification tables. The transmit 
frame has no data field.
The receive frame has a 440-byte data field. This 
consists of an 8-byte total accumulated number of 
trip events, followed by six 72-byte strings for the 
six most recent trip events as shown below.
The nine bytes of data for each trip event history is listed below. The data contains the multi-
plier to adjust the decimal point. Divide the data by that factor to derive the actual value.
