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).

Function:
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)

Enter the current limit trip delay in seconds.
*
s]
When the output current reaches the current
limit (F-43 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
Enter the torque limit trip delay in seconds.
*
s]
When the output torque reaches the torque
limits (F-40 Torque Limiter (Driving) and
F-41 Torque Limiter (Braking)), 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.
