3.5 Alarm Mode
If an abnormal condition arises, the protective function is invoked and issues an alarm, then the inverter
automatically enters Alarm mode. At the same time, an alarm code appears on the LED monitor.
3.5.1 Releasing the alarm and switching to running mode
Remove the cause of the alarm and press the key to release the alarm and return to Running mode. The alarm
can be removed using the key only when the alarm code is displayed.
3.5.2 Displaying the alarm history
It is possible to display the most recent 3 alarm codes in addition to the one currently displayed. Previous alarm
codes can be displayed by pressing the / key while the current alarm code is displayed.
3.5.3 Displaying the status of inverter at the time of alarm
When the alarm code is displayed, you may check various running status information when the alarm occurred
(output frequency and output current, etc.) by pressing the key. The monitor item number and data for each
running status information will be displayed alternately.
Further, you can view various information items on the running status of the inverter using the / key. The
information displayed is the same as for menu number 6 “Alarm Information” in Programming mode. Refer to Table
3.4-14 in “3.4.6 Reading alarm information “Alarm Information:
6.al”
.”
Pressing the key while the running status information is displayed returns to the alarm code display.
When the running status information is displayed after removal of the alarm cause, pressing the key
twice returns to the alarm code display and releases the inverter from the alarm state. This means that
the motor starts running if a run command has been received by this time.
3.5.4 Switching to programming mode
You can also switch to Programming mode by pressing " + keys” simultaneously with the alarm displayed,
and modify the function code data.
