PARAMETERS
Example) When reading the C3 (Pr. 902) and C6 (Pr. 904) settings from the inverter of station 0
To read/write C3 (Pr. 902) and C6 (Pr. 904) after inverter reset or parameter clear, execute from 1) again.
Parameter clear
All 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 466 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.
In the password locked status (refer to page 310), only H9966 and H55AA
(all parameter clear) are valid.
*1 Turning OFF the power supply while clearing parameters with H5A5A or
H55AA also clears the communication parameter settings back to the initial
values.

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.
