7.4Explanation of Screen Display

•When the inverter is turned on, the latest display appears. However, when the display unit for data of the commands F2 to F14 is turned off, the commands (F2 to F14) are displayed. (d10 and d11 excluded)

•Data during running in any function mode or extension function mode can be displayed. Even if data cannot be changed during running, data can be monitored.

•In each of the function modes , , ,, and, data

can be changed even during running. In other function modes and extension function modes, data cannot be set during running.
