G11.1
/ Trip time

0 to 60s,
OFF=61

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

OFF
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

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.

G11.5
/ Trip time
because of low
input voltage
0.0 – 60s,
OFF=60.1
5s
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

G11.7
/ Trip time
because of high
input voltage
0.0 – 60s,
OFF=60.1
5s
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 740V and the range will be 726 – 759V.

G11.8
/ Trip
delay time due to
output voltage
imbalance
0.0s – 10s,
OFF=10.1
1.0s
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’.

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.

N
A PTC sensor can be connected directly to the drive to detect high
motor temperature (terminals 8 and 9 on control board). If PTC
value is higher or equal than 1K7, a fault will be generated in the
drive 'F40 EXT / PTC' and it will not be reset until resistance value
decreases to 260
Ω
. On the other hand, if the value decreases
below 100
Ω
, a fault will be generated too, and it will not be reset
until resistance value was higher or equal than 160
Ω
.
