SP-11 Line Voltage at Input Fault
Range:
Function:
342 V
*
[180 -
600 V]
This parameter defines the threshold voltage
at which the selected function in
SP-10 Line
failure
should be activated. It may be
considered to choose 90% of the nominal
mains as the detection level, depending on
the supply quality. For a supply of 380 V
SP-11 Line Voltage at Input Fault
should thus
be set to 342 V. This results in a DC detection
level of 462 V (
SP-11 Line Voltage at Input Fault
* 1.35)
SP-12 Function at Line Imbalance
Operation under severe main imbalance conditions reduces the
lifetime of the motor. Conditions are considered severe if the
motor is operated continuously near nominal load (e.g. a pump
or fan running near full speed).

SP-14 Kin. Backup Time Out
Range:
Function:
60 s
*
[0 - 60
s]
This parameter defines the Kinetic Backup Time
Out in flux mode when running on low voltage
grids. If the supply voltage does not increase
above the value defined in
SP-11 Line Voltage at
Input Fault
+5% within the specified time, the
drive will then automatically run a controlled
ramp-down profile before stopping.

This parameter
specifies the Kinetic

Parameters to configure the trip delay do to Torque Limit
or Drive Fault.
SP-24 Trip Delay at Current Limit
Range:
Function:
60 s
*
[0 - 60
s]
Enter the current limit trip delay in seconds.
When the output current reaches the current
limit (
), a warning is triggered.
When the current limit warning has been contin-
uously present for the period specified in this
parameter, the frequency converter trips. Disable
the trip delay by setting the parameter to 60 s =
OFF. Thermal monitoring of the frequency
converter will still remain active.
SP-25 Trip Delay at Torque Limit
Range:
Function:
60 s
*
[0 - 60
s]
Enter the torque limit trip delay in seconds.
When the output torque reaches the torque
limits (
and
), a warning is
triggered. When the torque limit warning has
been continuously present for the period
specified in this parameter, the frequency
converter trips. Disable the trip delay by setting
the parameter to 60 s = Off. Thermal monitoring
of the frequency converter will still remain active.
SP-26 Trip Delay at Drive Fault
Range:
Function:
0 s
*
[0 - 35 s] When the frequency converter detects an over-
voltage in the set time trip will be effected after
the set time.
