ters that do not change during operation to prevent unwanted modifi-
cation.
• The set value of the "security" parameter (protect mode) limits the

tionship between set values and the range of protection. (Only modes

• When this parameter is set to "0", parameters are not protected.
• When this parameter is set to "5", operations in only the level 0 mode
can be selected, and the mode is not displayed on the menu display.
• When this parameter is set to "6", the "PV/Present SP" parameter
can only be monitored.

• This parameter disables key operation for switching run/reset or
auto/manual. For example, if you protect the key operation for switch-
ing auto/manual by the "key protect" parameter (protect mode) dur-
ing automatic operation, the controller cannot be set to the manual
mode, preventing manual operation of the controller during opera-
tion.
• The following table shows the relationship between set values and
keys that are protected.
