L300P 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.
