1
Fault The drive generates an 8001 ULC underload fault if the signal
has been continuously under the underload curve for a time
defined by parameter

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 generates an 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.

37.16 ULC frequency
table point 1 Defines the first of the five frequency points on the X-axis of
the user load curve.
The values of the parameters must satisfy: -500.0 Hz <
37.16
ULC frequency table point 1 < 37.17 ULC frequency table
point 2 < 37.18 ULC frequency table point 3 < 37.19 ULC
frequency table point 4 < 37.20 ULC frequency table point 5 <
