7.3.4 Active faults menu (M4)
The Active faults menu can be entered from the Main menu by pushing the Menu button right when the
location indication M4 is visible on the first line of the keypad display.
When a fault brings the frequency converter to a stop, the location indication F1, the fault code, a short
description of the fault and the fault type symbol (see Chapter 7.3.4.1) will appear on the display. In
addition, the indication FAULT or ALARM (see Figure 7-1 or Chapter 7.1.1) is displayed and, in case of a
FAULT, the
red led on the keypad starts to blink. If several faults occur simultaneously, the list of active
faults can be browsed with the Browser buttons .
The memory of active faults can store the maximum of 10 faults in the order of appearance. The display
can be cleared with the
Reset button and the read-out will return to the same state it was before the fault
trip. The fault remains active until it is cleared with the Reset button or with a reset signal from the I/O
terminal or fieldbus.
Note! Remove external Start signal before resetting the fault to prevent unintentional restart of the drive.
