SJ300 Inverter

Appendix B

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.

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.

The receive frame includes an ACK 
(acknowledge) character, followed by a
2-byte data field with the result.
