37.01 ULC output status
word
Displays the status of the monitored signal (
37.02
).
The status is shown only while the drive is running.
(The status word is independent of the actions and
delays selected by parameters
37.03
,
37.04
,
37.41
and
37.42
.)
This parameter is read-only.

0000h…FFFFh Status of the monitored signal. 1 = 1
37.02 ULC supervision signal
Selects the signal to be monitored. The function
compares
the absolute value of the signal against the load
curve.

37.03 ULC overload actions Selects how the drive reacts if the absolute value of
the monitored signal stays continuously above the
overload curve for longer than the value of 37.41 ULC
overload timer .
Disabled
Disabled No warnings or fault generated. 0
Warning The drive generates an A8C1 ULC overload warning if
the signal has been continuously over the overload
curve for a time defined by parameter 37.41 ULC
overload timer .
1
Fault The drive trips on 8002 ULC overload fault if the
signal has been continuously over the overload curve
for a time defined by parameter 37.41 ULC overload
timer .
2
Warning/Fault The drive generates an A8C1 ULC overload warning if
the signal has been continuously over the overload
curve for half of the time defined by parameter 37.41
ULC overload timer .
The drive trips on 8002 ULC overload fault if the
signal has been continuously over the overload curve
for a time defined by parameter 37.41 ULC overload
timer .

Bit Name Description
0 Under load limit 1 = Signal lower than the underload curve.
1 Within load range 1 = Signal between the underload and overload curve.
2 Overload limit 1 = Signal higher than the overload curve.
3 Outside load limit 1 = Signal lower than the underload curve or higher than
the overload curve.
