In Keypad Input Display settings, put a check mark on [Alarm Display] in [Alarm Settings] tab. By doing so, you can decide the input range of keypad. If you input the value that is out of input range, it makes the sound of “Pi Pi Pi” and you cannot input the value.

Alarm Display can be used only when [Display Format] is [Absolute] or [Relative].
Also, if the out-of-range value is inputted by PLC, use the color display set on [Alarm Color].
