ASCII Mode Communications
Command – 08
Command – 09
The 08 command initializes the inverter parameters to the factory default values. First, you
must set B84 (use command 07) to specify whether you want to clear the trip history at the
same time. Also, set B85 to specify the country code for the initialization (use command 07).
The frame format of command 08 follows the
diagram and specification table.
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 09 command verifies whether or not it is
possible to set a particular parameter in the
EEPROM. The frame format of command 08
follows the diagram and specification table.
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 includes an ACK
(acknowledge) character, followed by a
2-byte data field with the result.
Element Description
