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.

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. (Turning OFF the power supply
while clearing parameters with H5A5A or H55AA sets back the
communication parameter settings to the initial settings.)
Executing clear will clear the instruction code HEC, HF3, and HFF
settings.
In the password locked status (refer to page 318), only H9966 and
H55AA (all parameter clear) are valid.
