7.4.6 Fault history menu (H5)

The Fault history menu can be entered from the Main menu by pushing the Menu button right when
the location indication H5 is visible on the keypad display.

All faults are stored in the Fault history menu in which you can browse through them using the
Browser buttons. You can return to the previous menu anytime by pushing the Menu button left.

The memory of the frequency converter can store a maximum of 5 faults in the order of appearance.
The latest fault carries the indication H5.1, the second latest H5.2 etc. If there are 5 uncleared faults
in the memory the next occurring fault will erase the oldest from the memory.

Pressing the Enter button for about 2 to 3 seconds resets the whole fault history.
