Danfoss VLT 5000 Series User Manual

7. If the intermediate circuit voltage is higher
than the intermediate circuit voltage -2% be-
fore the brake test, discontinue the brake
check and give off a warning or alarm.
8. Brake check OK.
Description of choice:
If Off [0] is selected, this function will still monitor
whether the brake resistor and the brake IGBT short-
circuit during operation, in which case it will give off a
warning. If Warning [1] is selected, the brake resistor
and brake IGBT will be monitored with respect to short-
circuiting. In addition, on power-up it will be checked
whether the brake resistor has been disconnected.
NOTE
A warning in connection with Off [0] or
Warning [1] can only be removed by dis-
connecting the mains supply and turning
it back on, provided the fault has been
corrected. Please note that in connection
with Off [0] or Warning [1] the adjustable
frequency drive will continue even if a fault
has been found.
In the case of Trip [2], the adjustable frequency drive
will cut out while giving an alarm (trip locked) if the
brake resistor has short-circuited or been disconnec-
ted or if the brake IGBT has short-circuited.
405 Reset function (RESET MODE)
Value:
Manual reset (MANUAL RESET) [0]
Automatic reset x 1 (AUTOMATIC X 1) [1]
Automatic reset x 2 (AUTOMATIC X 2) [2]
Automatic reset x 3 (AUTOMATIC X 3) [3]
Automatic reset x 4 (AUTOMATIC X 4) [4]

Automatic reset x 9 (AUTOMATIC X 9) [9]
Automatic reset x 10 (AUTOMATIC X 10) [10]
Function:
This parameter makes it possible to select the reset
function desired after tripping.
After reset, the adjustable frequency drive can be re-
started.
Description of choice:
If Manual reset [0] is selected, reset must be effected
via the [RESET] key or via the digital inputs.
If the adjustable frequency drive is to carry out an au-
tomatic reset (1-10 times) after tripping, select data
value [1]-[10].
NOTE
The internal AUTOMATIC RESET coun-
ter is reset 10 minutes after the first AU-
TOMATIC RESET has occurred.
Warning: The motor may start without
warning.
406 Automatic restart time
(AUT RESTART TIME)
Value:
0 - 10 sec.
5 sec.
Function:
This parameter allows setting of the time from tripping
until the automatic reset function begins.
It is assumed that automatic reset has been selected
in parameter 405.
Description of choice:
Set the desired time.
407 Mains failure
(MAINS FAILURE)
Value:
No function (NO FUNCTION) [0]
Controlled ramp-down
(CONTROL RAMP DOWN) [1]
Controlled ramp-down and trip
(CTRL. RAMP DOWN-TRIP) [2]
