E.4 Using the auxiliary back-up supply
1. Apply the AC supply and the auxiliary back-up supply to the Drive (in
either order).
2. The Drive and motor will run normally while the AC supply is
present. If the AC supply fails while the motor is running, the Drive
will behave according to the setting of parameter
6.03 AC supply
loss mode selector (see Chapter 9 Advanced Parameters on page
51).
3. The motor will be decelerated to rest and the display (version _ AN )
will show trip UU (under-voltage trip).
4. The control circuits remain active.
5. While the Drive is tripped, it will not be possible to edit any
parameters, or to position the motor (if the connections for this have
been made). To disable the trip, close the
UU TRIP DISABLE
contact. While the contact is closed, the AC supply is prevented from
being applied to the Drive and the display (version _
AN ) shows
StbY .
6. To allow the AC supply to be re-connected, stop the motor (if it is
running on the auxiliary back-up supply) and open the
UU TRIP
DISABLE contact.
