- / 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.)
ULC output status

This parameter is read-only.
1 = Monitored signal is below the underload curveUnder load limitb0
Reservedb1
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.

0No action taken.Disabled
1The drive generates a warning (A8BE ULC overload).Warning
2Drive trips on 8002 ULC overload.Fault
3The 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.

37.4
0No action taken.Disabled
1The drive generates a warning (A8BF ULC underload).Warning
2Drive trips on 8001 ULC underload.Fault
3The drive generates a warning (A8BF ULC underload)
if the signal stays continuously below the underload
Warning/Fault
curve for half of the time defined by 37.42 ULC
underload timer.
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.
