To move to the protect level, press the O and M Keys simultaneously for<br />

at least three seconds in operation level or adjustment level. (See note.)<br />

Note The key pressing time can be changed in the Move to Protect Level<br />

Time parameter (advanced function setting level).<br />

The protect level protects parameters that are not changed during Controller<br />

operation until operation is started to prevent them from being modified<br />

unintentionally.<br />

There are four types of protection: operation/adjustment protect, initial<br />

setting/communications protect, setting change protect, and PF Key protect.<br />

The protect level settings restrict the range of parameters that can be<br />

used.<br />

The following table shows the relationship between set values and the range<br />

of protection.<br />
