All parameters return to the initial values.
Any of four different all clear operations are performed according to
the data.
When all parameter clear is executed for H9696 or H9966,
communication-related parameter settings also return to the initial
values. When resuming operation, set the parameters again.

REMARKS
⋅
Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
⋅
For the instruction codes HFF, HEC and HF3, their values are held once written but cleared to zero when an inverter reset or all
clear is performed.
