■ LED monitor
In Running mode, the LED monitor displays running status information (output frequency, current or
voltage); in Programming mode, it displays menus, function codes and their data; in Alarm mode, it
displays an alarm code which identifies the error factor if the protective function is activated.
If one of LED4 through LED1 is blinking, it means that the cursor is at this digit, allowing you to change
it.
If the decimal point of LED1 is blinking, it means that the currently displayed data is a PID process
command, not the frequency data usually displayed.

■ Repeat function of / keys
/ keys have a repeat function which helps you change displayed data speedily as follows:
Usually you press
/ keys once to increase or decrease the displayed value by 1, respectively.
If you hold down
either key so as to activate the repeat function, the displayed value will keep changing
in steps of 1 speedily. Note that when changing some function code data during running of the inverter
(not always possible), the displayed data will keep changing more slowly. This is to ensure safe and
stable operation.
