232 Parameters
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.
3
37.04 ULC underload
actions
Selects an action taken if the signal (37.02) stays under
the underload curve for a defined time.
Disabled
Disabled No warnings or fault generated. 0
Warning The drive generates an A8C4 ULC underload warning if
the signal has been continuously under the underload
curve for a time defined by parameter 37.42 ULC
underload timer.
1
Fault The drive trips on 8001 ULC underload fault if the signal
has been continuously under the underload curve for a
time defined by parameter 37.42 ULC underload timer.
2
Warning/Fault The drive generates an A8C4 ULC underload warning if
the signal has been continuously under the underload
curve for half of the time defined by parameter 37.42 ULC
underload timer.
The drive trips on 8001 ULC underload fault if the signal
has been continuously under the underload curve for a
time defined by parameter 37.42 ULC underload timer.

37.11 ULC speed table point
1
Defines the first of the five speed points on the X-axis of
the user load curve.
The values of the parameters must satisfy: -30000.0 rpm
<
37.11 ULC speed table point 1 < 37.12 ULC speed table
point 2 < 37.13 ULC speed table point 3 < 37.14 ULC
speed table point 4 < 37.15 ULC speed table point 5 <
30000.0 rpm.
Speed points are used if parameter 99.04 Motor control
mode is set to Vector or if 99.04 Motor control mode is set
to Scalar and the reference unit is rpm.
The five points must be in order from lowest to highest.
The points are defined as positive values, but the range is
symmetrically effective also in the negative direction. The
monitoring is not active outside these two areas.
