- / uint16Displays the status of the monitored signal. (The status
word is independent of the actions and delays selected by
parameters 37.3, 37.4, 37.41 and 37.42.)

1 = Monitored signal is above the overload curveOver load limitb2
Reservedb3…15
1 = 10000h…FFFFh
Not selected / uint32Selects the signal to be monitored. The function compares
the absolute value of the signal against the load curve.

Disabled / uint16Selects how the drive reacts if the absolute value of the
monitored signal stays above the overload curve for longer
than the value of 37.41 ULC overload timer.
ULC overload actions37.3
0No action taken.Disabled
1
The drive generates a warning (A8BE ULC overload).
Warning
2
Drive trips on 8002 ULC overload.
Fault
3
The drive generates a warning (A8BE ULC overload) if the
signal stays continuously above the overload curve for half
of the time defined by 37.41 ULC overload timer.
Warning/Fault
The drive trips on 8002 ULC overload if the signal stays
continuously above the overload curve for the time defined
by 37.41 ULC overload timer.
Disabled / uint16Selects how the drive reacts if the absolute value of the
monitored signal stays below the underload curve for longer
than the value of 37.42 ULC underload timer.

1
The drive generates a warning (A8BF ULC underload).
Warning
2
Drive trips on 8001 ULC underload.

3
The drive generates a warning (A8BF ULC underload) if
the signal stays continuously below the underload curve
for half of the time defined by 37.42 ULC underload timer.
Warning/Fault
The drive trips on 8001 ULC underload if the signal stays
continuously below the underload curve for the time defined
by 37.42 ULC underload timer.
