Using the Key Protect Level
• To move to the Protect Level, press the
O
and
M
Keys simultaneously for at least three seconds in
Operation Level or Adjustment Level.*
* 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 Controller operation until
operation is started to prevent them from being modified unintentionally.
There are four types of protection: operation/adjustment protect, initial setting/communications
protect, setting change protect, and PF Key protect.
• The protect level settings restrict the range of parameters that can be used.
