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 C3 (Pr. 902) and C6 (Pr. 904) after inverter reset or parameter clear, execute from 1) again.

Parameter clear
All parameter clear
Write HFC
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 390 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.
Only H9966 and H55AA (all parameter clear) are valid during
the password lock.

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.
