Communication operation and setting
Example) When reading the
C3 (Pr. 902) and C6 (Pr. 904)
settings from the inverter of station No. 0
To read/write

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.

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.
