H9696: Inverter reset
As the inverter is reset at start of communication by the computer,
the inverter cannot send reply data back to the computer.

H9666: Inverter reset
When data is sent normally, ACK is returned to the computer
and then the inverter is reset.

All parameters return to the initial values.
Whether to clear communication parameters or not can be
selected according to data. (: Clear, ×: Not clear)
Refer to page 56 for parameter clear, all clear, and communication
parameters.
When clear is executed for H9696 or H9966, communication-
related parameter settings also return to the initial values. When
resuming operation, set the parameters again.
Executing clear will clear the instruction code HEC, HF3, and HFF
settings. During password lock, only all parameter clear is
available with H9966 and H55AA.
