10-1 Alarm Display and Remedies

10-1-1 Alarm Display

If an error occurs, the inverter shuts off its output ("trip"), turns ON the ALARM LED, and displays an
alarm code. With the alarm code displayed, you can rotate the Jog dial clockwise to view the detailed
information such as the output frequency, current, and main circuit DC voltage when the alarm signal
was output.
Before resetting the alarm, be sure to investigate the cause of the trip and remove the trip factor(s)
according to the displayed alarm code.
Note that, during an inverter trip, you cannot change parameter settings and data cannot be written to
the EEPROM via communications. To change parameter settings, cycle the power supply, or reset the
trip in advance.
This section describes how to deal with troubles that may occur after you start using the inverter.
Fault Monitor Display
Use the Fault Monitor 1 to 6 (d081 to d086) to check the current alarm, as well as the past alarms. The
Fault Monitor 1 (d081) displays information on the latest alarm.
