You can write the operation mode and set frequency to the inverter, batch-clear the
alarm definitions, and clear all parameters.

The above data are written as soon as the write completion turns on after the write
command has turned from off to on.
(Alarm definition batch clear (D9146) and all parameter clear (D9147) turn on at
completion of clear.)
To write the data again, the write command must be turned off once, then on again.

Write command

1) In user sequence, user
    data is stored into write 
    data area (D914n).

2) In user sequence, write
    command is turned on.

4) After confirmation of write
    completion, write command
    is turned off.

3) Turns on when inverter CPU completes data 

    write to inverter.

    Alarm definition clear and parameter

    clear turn on at completion of clear.

    0 written to D9150 indicates normal completion.

    Any value other than 0 indicates abnormal completion.

5) Inverter CPU confirms that
    write command is off and
    turns off write completion.
