5-7 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 Digital 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.
 Operation/Adjustment Protect
Displaying and changing settings in Operation Level and moving to Adjustment Level are restricted.
The following table shows the relationship between set values and the range of protection.
 Initial Setting/Communications Protect
This protect level restricts movement to the Initial Setting Level, Communications Setting Level, and
Advanced Function Setting Level.
Application Example: To enable setting only the SP, set both the Operation/Adjustment Protect
parameter and the Initial Setting/Communications Protect parameter to 2.
5-7-1 Protection
