7.4.4Active faults menu (F4)

The Active faults menu can be entered from the Main menu by pushing the Menu button right when the location indication F4 is visible on the keypad display.

The memory of active faults can store the maximum of 5 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.

Note! Remove external Start signal before resetting the fault to prevent unintentional restart of the drive.

Normal state, no faults:

7.4.4.1Fault types

In the NXL frequency converter, there are two different types of faults. These types differ from each other on the basis of the subsequent behaviour of the drive. See Table 7-3. Fault types.
