Overload protection is a combination of parameters G11.11, G11.12
and G11.13. Drive turns off its output generating a fault 'F57 PUMP
OVERLOA' when the output current of the drive is higher than the
current set in G11.11 for the time adjusted in parameter G11.13.
By means of parameter G11.12, we can adjust the value of low-
pass filter for the current reading to avoid oscillations.

It allows the possibility of protecting the pump from underload
status.
OPT
FUNCTION
N=NO Underload
protection disabled.
Y=YES Underload
protection enabled.
To protect the pump from underload status is necessary to follow
the next steps:
Set this parameter to ‘YES’.
Set an underload current value (in G11.15) below which the first
detection condition will be met.
Set an underload speed value (in G11.16) above which the second
detection condition will be met.
Set a delay time to activate underload protection (in G11.17), once
elapsed, last underload condition will be activated.
If three previous conditions are given, the drive will stop the pump to
protect it from underload status.
YES
15 ULD CUR=___A

G11.15
/
Underload
current

1.50)·In
∗
Setting of the underload current below which the first detection
condition to activate the protection is met. This parameter operates
together with parameters G11.16 and G11.17.
YES
16 ULD SPD=+100%
UNDERLOAD SPEED
G11.16
/
Underload speed
+0.0% to

+100%
Setting of the underload speed above which the second detection
condition to activate the protection is met. This parameter operates
together with parameters G11.15 and G11.17.
YES
17 ULD DELY=10s
UNDERLOAD DELAY
G11.17
/ Delay
time to activate
underload
protection
0 – 999s
10s
Setting of the delay time to activate the underload protection. The
drive will wait for this time before activating the protection and then
will stop. This parameter operates together with parameters G11.15
and G11.16.
YES
∗
This value depends on the drive size.
