1 SP LIM TO=OFF
TMAX LIMITIN SPD
G11.1 / Trip time
because of
speed limit
0.1 to 60s,
OFF
If the drive is operated continually at the speed limit for the time set in this screen
the drive generates a fault 'F49 SPD LIMIT'.
YES
2 STOP TO=OFF
TIMEOUT STOPPING
G11.2 /
Maximum time
for stop limit
OFF=0.0 to
999s
It supplies a safety function to stop the drive automatically if the motor has not
stopped after the time set in this parameter has elapsed and if the drive has
received a stop command. The drive will fault on 'F45 STOP T/O'.
This function is used to protect from uncontrolled stops where motor needs a
longer time than the predict time to stop. As well as other protections integrated
into the drive, this time can be set to turn off the output voltage and stop the motor
by free run if this time has elapsed and the motor has not stopped completely.
Controlled stop time is calculated in standard conditions during system operation.
Stop limit time should be set to a higher value than controlled stop time value.
YES
3 GND I LIMIT=10%
GND CURR MAX LEV
G11.3 / Ground
fault detection
OFF,
0 – 30% In
It allows drive to turn off its output to the motor generating a fault 'F20 GROUND
FLT' automatically if the leakage current value is above the value set in this
parameter.
YES
4 LOW VOLT=360V
LO INPUT VOLTAGE
G11.4 / Low
input voltage
level
323 – 425V
586 – 621V
Input low voltage protection is a combination of parameters G11.4 and G11.5.
Drive turns off its output generating a fault 'F14 LW V IN' when average voltage,
measured in the drive input, is below the value set in G11.4 for the time set in
G11.5.
In case of the drive has a power supply of 690V, the default value in G11.4 will be
600V and the range will be 586 – 621V.
YES
5 LOW V TO=5s
LO INP VOL TIMEO
G11.5 / Trip time

0.0 – 60s,
OFF
YES
6 HIGH VOLT=500V
HI INPUT VOLTAGE
G11.6 / High
input voltage
level
418 – 587V
726 – 759V
Input high voltage protection is a combination of parameters G11.6 and G11.7.
Drive turns off its output generating a fault 'F13 HI V IN' when average voltage,
measured in the drive input, is above the value set in G11.6 for the time set in
G11.7.
In case of the drive has a power supply of 690V, the default value in G11.6 will be
750V and the range will be 726 – 759V.
YES
7 HI V TO=5s

0.0 – 60s,
OFF
YES
8 Dlasy VO = 5s
VOUT asyTRIP DLY
G11.8 / Trip
delay time due to
output voltage
imbalance
0.0s – 10s,
OFF
It allows setting a delay time before tripping once output voltage imbalance has
been detected. Once this time is elapsed, the drive trips due to ‘F18 IMB V OUT’.
YES
9 LOW V BHV=1
G11.9 /
Performance in

power loss
0 – 3
Modifies the drive response following an input power loss while motor is running
according to next adjusts:
OPT.
DESCRIPTION
FUNCTION
0
NO FAULT
No action will be done by the drive.
1
FAULTS
Drive will trip because of fault 'F11
VIN LOSS'.
2
STOP
Drive will not trip because of fault
and it will try to control the motor to
a stop while DC Bus voltage level
allows it.
3
DipVoltRecover
After a momentary power loss has
occurred, an algorithm of controlled
recovery is activated. Due to this,
the motor speed is not affected
significantly.
In case of loads with high inertia,
the reduction of the speed will be
minimal.
YES
