6. DISPLAY AND OPERATION
6.4 Alarm mode
The current alarm, past alarm history and parameter error are displayed. The lower 2 digits on the
display indicate the alarm number that has occurred or the parameter number in error. Display examples
are shown below.
Name Display Description
Indicates no occurrence of an alarm.
Current alarm
Indicates the occurrence of overvoltage (AL.33).
Flickers at occurrence of the alarm.
Indicates that the last alarm is overload 1 (AL.50).
Indicates that the second alarm in the past is overvoltage (AL.33).
Indicates that the third alarm in the past is undervoltage (AL.10).
Indicates that the fourth alarm in the past is overspeed (AL.31).
Indicates that there is no fifth alarm in the past.
Alarm history
Indicates that there is no sixth alarm in the past.
Indicates no occurrence of parameter error (AL.37).
Parameter error No.
Indicates that the data of parameter No. 1 is faulty.
Functions at occurrence of an alarm
(1) Any mode screen displays the current alarm.
(2) Even during alarm occurrence, the other screen can be viewed by pressing the button in the operation
area. At this time, the decimal point in the fourth digit remains flickering.
(3) For any alarm, remove its cause and clear it in any of the following methods (for clearable alarms,
refer to Section 10.2.1):
(a) Switch power OFF, then ON.
(b) Press the "SET" button on the current alarm screen.
(c) Turn on the alarm reset (RES).
(4) Use parameter No. 16 to clear the alarm history.
(5) Pressing "SET" on the alarm history display screen for 2s or longer shows the following detailed
information display screen. Note that this is provided for maintenance by the manufacturer.
(6) Press "UP" or "DOWN" to move to the next history.
