:Full power braking time
Adjustment range : 0 to 400.0 s
Factory setting
: 3.0 s
This parameter defines for how long the braking resistor can
withstand the maximum braking voltage (780V or 390V)
without damage. It is used to determine the time before the
drive trips due to braking overload.
CAUTION:
If this parameter is left at 0, the braking resistor will not
be protected.
10.31
:Full power braking period
Adjustment range : 0 to 25.0 min
Factory setting
: 1.0 min
This parameter defines the time period which must elapse
between two consecutive braking periods of maximum
braking power as defined by parameter
1 1 0 0 . . 3 3 0 0 . It is used to
configure the thermal time constant for the resistor used.
CAUTION:
If this parameter is left at 0, the braking resistor will not
be protected.
10.32
:Not used
10.33
:Drive reset
Adjustment range : 0 or 1
Factory setting
: 0
A 0 to 1 change in this parameter will cause a drive reset.
If a remote drive reset is required, a terminal must be
assigned to this parameter.
If the drive trips due to IGBT overcurrent, either at the output
bridge or the braking transistor, the drive cannot be reset for
10 seconds (IGBT recovery time).
10.34
:No. of auto-reset attempts
Adjustment range : 0 to 5
Factory setting
: 0
0: The drive will not be reset automatically. A command
must be sent.
1 to 5:
The drive will be reset automatically as many times as
has been programmed.
When the counter reaches the authorised number of drive
resets, the drive is disabled and will not auto-reset. The last
trip can only be reset via a command.
If no trips occur, the counter is decremented by one value
every 5 minutes.
10.35
:Auto reset delay automatic
Adjustment range : 0 to 25.0 s
Factory setting
: 1.0 s
This parameter defines the time between the drive tripping
and the auto-reset (as long as the stop has lasted the
minimum time for trips involving overcurrents).
10.36

:Action on trip detection
Adjustment range : 0 or 1
Factory setting
: 0
0 (Free): Freewheel stop on all trip types.
1 (Ctld):
The drive will control deceleration before tripping on
low-priority trips it.AC, Oht1, Oht2, th, OLd1, CL1, CL2, CL3,
SCL, EEF, Fbus, tr05, tr10.
10.38
:User trip
Adjustment range : 0 to 50
Factory setting
: 0
This parameter is used to generate user trips, via the serial
link.
Trips generated by the user will be indicated by trxx in the trip
table, xx being the trip code. Only values
≥
45 can generate a
trip.
Users wishing to reset the drive via the serial link can do so
by giving this parameter the value 100.
10.39
:Braking energy overload accumulator
Adjustment range : 0 to 100.0%
This parameter gives an indication of the braking resistor
temperature modelled according to parameters
1 1 0 0 . . 3 3 0 0 and
1 1 0 0 . . 3 3 1 1 . A zero value means that the resistor is close to the
ambient temperature and 100% is the maximum temperature
(trip level).
