Chap. 3 OPERATION USING THE KEYPAD
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.
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.
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.
Displaying the status of inverter at the time of alarm
When the alarm code is displayed, you may check various running status information (output frequency and output current,
etc.) by pressing the
key. The item number and data for each running information will be displayed alternately.
Further, you can view various pieces of information on the running status of the inverter using the
/ key. The information
displayed is the same as for Menu #6 "Alarm Information" in Programming mode. Refer to Table 3.16 in Section 3.4.7,
"Reading alarm information."
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.
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.
Figure 3.7 summarizes the possible transitions between different menu items.
