14-12 Function at Mains 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).

VLT
Function:
This parameter defines the threshold voltage
at which the selected function in 14-10 Mains
Failure should be activated. It may be
considered to select 90% of the nominal
mains as the detection level, depending on
the supply quality. For a supply of 380 V
parameter 14-11 Mains Voltage at Mains Fault
should thus be set to 342 V. This results in a
DC detection level of 462 V
(parameter 14-11 Mains Voltage at Mains Fault
* 1.35)
NOTICE
Note for converting between VLT 5000
and FC 300:
Even though the setting of the Mains
Voltage at Mains Fault is the same for
VLT 5000 and FC 300, the detection
level is different. Use the following
formula to obtain the same detection
level as in VLT 5000:
parameter 14-11 Mains Voltage at
Mains Fault (VLT 5000 level) = Value
used in VLT 5000 * 1,35/sqrt(2).

Function:
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 14-11 Mains Voltage
at Mains Fault +5% within the specified time, the
drive will then automatically run a controlled
ramp-down profile before stopping.

NOTICE
The motor may start without warning. If the specified
number of AUTOMATIC RESETs is reached within 10
minutes, the frequency converter enters [0] Manual reset
mode. After the Manual reset is performed, the setting
of 14-20 Reset Mode reverts to the original selection. If
the number of automatic resets is not reached within 10
minutes, or when a Manual reset is performed, the
internal AUTOMATIC RESET counter returns to zero.
