All parameters return to the factory settings.
Any of four different all clear operations are performed
according to the data.
When all parameter clear is executed for H9696 or
H9966, communication-related parameter settings also
return to the factory settings. When resuming operation,
set the parameters again.
* Pr. 75 is not cleared.

38 and Pr. 39 (Instruction codes A6 and A7).
*2. When a voltage is given to the external terminal to
make bias or gain calibration, the data value written
is 4 digits.

REMARKS
For the instruction codes HFF, HEC, their set values are held once they are written, but
changed to 0 when the inverter is reset or all clear is performed.
