7-1 Error Display and Remedial Actions
Error Display
Upon detecting an error, the Inverter cuts off (trips) the output, the ALARM LED indicator is lit,
and an error code is displayed. By pressing the Increment key while the error code is
displayed, the output frequency, current, DC voltage and other detailed information at the time
of occurrence of the alarm can be checked.
Before resetting the alarm, check each signal such as the RUN command.
Also before resetting the alarm, identify the cause of the trip based on the displayed error code
and remove the cause.
This Chapter explains how to handle problems that may occur after operation of the Inverter is
started.
Method for Resetting Trip
A trip can be reset by one of the following two methods:
Depending on its factor, the trip may not be reset using the reset terminal. In this case, reconnect
the power supply.

Press the STOP/RESET Key.
Allocate Reset (18: RS) to a multi-function input terminal, and turn this terminal ON and then
turn it OFF.

Note: This is the Inverter condition when a trip has occurred. It may be
different from the apparent operation of the motor.
(During PID control or when the frequency is input using an analog signal, the
Inverter may be repeating brief decelerations/accelerations due to analog signal
fluctuation, etc., even when the motor appears to be operating at a constant speed.)
