(5) Parameter clear (D9147)
Writing H9696 or H9966 to D9147 clears all parameters. Writing H5A5A or
H55AA to D9147 clears the parameters other than the communication
parameters (Refer to the Inverter instruction manual (applied)).
At completion of clear, the write completion signal (X27) turns on, and at the
same time, 0 is set to D9150. If any value outside the setting range is written or
write is performed during inverter operation, HFFFF is set to D9150 as soon as
the write completion signal (X27) turns on, resulting in abnormal completion. If
abnormal completion occurs, the parameters are not cleared.

Abnormal write
Stores H9696 (all parameter
clear code) to D9146 and turns
on alarm definition batch clear
command.

All parameter clear request
Turns on all parameter
clear request pulse.
Check whether all parameter
clear signal turned on to judge
whether write was performed
normally or not.
