(4) Alarm definition batch clear (D9146)
Writing H9696 to D9146 batch-clears the alarm definitions.
At completion of clear, the write completion signal (X26) 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 (X26) turns on, resulting in abnormal completion.
If abnormal completion occurs, the alarm definitions are not cleared.
