7.2.12. Write Protection Setting
The write protection setting is used to prevent careless changes of
parameters. All Pn parameters and some of the Fn functions become write
protected by setting the function Fn010.
Password setting values are as follows:
• “0000”: Write enabled (releases write protected mode.)
• “0001”: Write prohibited (parameters become write protected at the
next power ON.)
