The increment is 0.001 and the data format is E2 or A2 when the following conditions are met: Pr. 37 = "0.01 to 9998," Pr. 144 = "2 to 10," and the
instruction code HFF = "01."
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.

H9696: Clears the fault history as a batch
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 64 for parameter clear, all clear, and communication
parameters.
All parameter clear

HFC
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.
