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.
Example) When reading the C3 (Pr. 902) and C6 (Pr. 904) settings from the inverter of station 0

Code
H9696: Inverter reset
As the inverter is reset at start of communication by the
computer, the inverter cannot send reply data back to the
Write HFD computer.
H9666: Inverter reset
When data is sent normally, ACK is returned to the computer
and then the inverter is reset.
Write HF4 H9696: Faults history batch clear
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.
