4-9-1 Protection
• To move to the protect level, press the O and M Keys simultaneously for
at least three seconds in operation level or adjustment level. (See note.)
Note The key pressing time can be changed in the Move to Protect Level
Time parameter (advanced function setting level).
• The protect level protects parameters that are not changed during Con-
troller operation until operation is started to prevent them from being mod-
ified unintentionally.
There are four types of protection: operation/adjustment protect, initial
setting/communications protect, setting change protect, and PF Key pro-
tect.
• The protect level settings restrict the range of parameters that can be
used.
