Inverter failure is divided into Alarm, and Light alarm. If the former occurs, which appears the inverter
immediately trips, if the latter occurs, which the L-AL appears and PU LED blinks on the LED moni-
tor, but the inverter continues to run. The Light alarm object should defined with function codes 04.81
and 04.82 beforehand. If the Light alarm [mLALM](data = 98) is distributed to general output terminal
(function parameters 01

terminal upon occurrence of a light alarm.
Programming mode provides you with these functions--setting and checking function code data,
monitoring maintenance information and checking input/output (I/O) signal status. These functions
can be easily selected with a menu-driven system. Table 3.4 lists menus available in Programming
mode
.
When the inverter enters Programming mode from the second time on, the menu selected last in
Programming mode will be displayed.
Displays the function code selected and its data on the same
screen. Also this menu is used to change the function code data
or check whether the data has been changed from the factory
default.
■
Check a light alarm
If a light alarm appears, it displays L-AL on the LED monitor. If the light alarm would be required to
check, enter programming mode by pressing key and check on “Maintenance Information” E_36.
Additionally, To check the past light alarm ,it’s also possible to check on E_37 (light alarm (previous))
~E_39(light alarm (previous 3)) simultaneously. Refer to “4.4 Maintainance Information”
■
Remove the current light alarm
After checking the current light alarm, to switch the keypad from the L-AL indication back to the
running status display, press the key in Running mode If the light alarm has been removed, the
PU LED doesn’t blink,and general output signal[mLALM] turns OFF. If not, PU LED and general
output [mLALM] will keep showing “Light alarm” status.
