Command – 08; Command – 09 - Hitachi L300P Series Instruction Manual

Command – 08
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.
