ASCII Mode Communications
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.
Element Description
STX Control code (STart of TeXt)
Node Node (station) address of inverter
Command Transmission command
BCC Block check sum code
[CR] Control code (carriage return)
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.
