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)
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.
*
Turning OFF the power supply while clearing parameters with H5A5A or
H55AA also clears the communication parameter settings back to the
initial settings.

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.
