Parameters — Special functions
405 Reset function (RESET MODE)
Value:
Manual reset (MANUAL RESET)
Automatic reset x 1 (AUTOMATIC X 1)
Automatic reset x 2 (AUTOMATIC X 2)
Automatic reset x 3 (AUTOMATIC X 3)
Automatic reset x 4 (AUTOMATIC X 4)
Automatic reset x 5 (AUTOMATIC X 5)
Automatic reset x 6 (AUTOMATIC X 6)
Automatic reset x 7 (AUTOMATIC X 7)
Automatic reset x 8 (AUTOMATIC X 8)
Automatic reset x 9 (AUTOMATIC X 9)
Automatic reset x 10 (AUTOMATIC X 10)
Function:
This parameter makes it possible to select the
reset function desired after tripping.
After reset, the frequency converter can be restarted.
Description of choice:
If Manual reset [0] is selected, reset must be effected
via the [RESET] key or via the digital inputs.
If the frequency converter is to carry out an
automatic reset (1-10 times) after tripping,
select data value [1]-[10].
NB!:
The internal AUTOMATIC RESET counter is
reset 10 minutes after the first AUTOMATIC
RESET has occurred.
Warning: The motor may start
without warning.
406 Automatic restart time
(AUT RESTART TIME)
Value:
0 - 10 min.
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.

409 Trip delay torque
(TRIP DELAY TORQ.)
Value:
0 - 60 sec. (OFF)
[0]
Function:
[1]
When the frequency converter registers that the
[2]
output torque has increased up to the torque limits
[3]
(parameter 221) in the set time, cutting out is
[4]
effected when that time has passed.
[5]
[6]
Description of choice:
[7]
Select how long the frequency converter is to be
[8]
able to run at the torque limit before cutting out. 60
[9]
sec. = OFF means that the time is infinite; however,
[10]
the thermal monitoring will still be active.
411 Switching frequency
(SWITCH FREQ.)
Value:
Depends on the unit output.
Function:
The set value determines the switching frequency of
the frequency converter. If the switching frequency
is changed, this may help to minimise possible
acoustic noise from the motor.
NB!:
The output frequency of the frequency converter
can never assume a value higher than 1/10
of the switching frequency.
Description of choice:
When the motor is running, the switching frequency is
adjusted in parameter 411 until the frequency has been
obtained at which the motor is as low-noise as possible.
NB!:
Switching frequencies higher than 3.0 kHz (4.5
5 min. kHz for 60°C AVM) lead to automatic derating of
the maximum output of the frequency converter.
412 Output frequency dependent switching
frequency
(VAR CARRIER FREQ)
Value:
Not possible (DISABLE)
Possible (ENABLE)
