Chapter 9 Monitor Functions
The Trip Mode displays the present failure status in case of a trip during operation. The type, operating frequency
and current of the present trip can be monitored and last 5 trips can be saved.
1) Present Failure Status Monitor
If a failure occurs, the present failure type is displayed as follows in the keypad display.
TRP current
Over Voltage (02)
01 Output Freq
48.30 Hz
02 Output Current
For the type and description of the failure, see 10.1.20. Table of Failures/Warnings
The inverter operating status at the time of a failure can be monitored and the followings items are recorded.
Displayed Information Function
1 Output Freq
The operating frequency at the time of
the failure
2 Output Current
The output current at the time of the
failure
3 Inverter State
Displays acceleration, deceleration,
steady speed operation and stop
4 DCLink Voltage Inverter DC power voltage
5 Temperature Inverter temperature
6 Input State Displays the input terminal status
7 Output State Displays the output terminal status
8 Trip On Time
9 Trip Run Time
Displays the time from the inverter
power ON to the failure
Displays the time from the inverter Run
to the failure
If you enter press the Reset key on the keypad or input the reset terminal of the terminal block in order to terminal the
failure status, the information on the currently displayed failure is saved as part of the failure history. In this case, what
was saved in Failure History 1(Last-1) is shifted to Failure History 2(Last-2)
The number next to the failure name represents the number of simultaneously occurring failures. Therefore, if more
than one failure occurs, you can monitor the type of them by pressing PROG.
