Parameters 233
37.15 ULC speed table point
5
Defines the fifth speed point.
See parameter 37.11 ULC speed table point 1.
1800.0 rpm
-30000.0…30000.0
rpm
Speed. 1 = 1 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 <
500.0 Hz.
Frequency points are used if parameter 99.04 Motor
control mode is set to Scalar and the reference unit is Hz.
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.
5.0 Hz
-500.0…500.0 Hz Frequency. 1 = 1 Hz
37.17 ULC frequency table
point 2
Defines the second frequency point.
See parameter 37.16 ULC frequency table point 1.
25.0 Hz
-500.0…500.0 Hz Frequency. 1 = 1 Hz
37.18 ULC frequency table
point 3
Defines the third frequency point.
See parameter 37.16 ULC frequency table point 1.
43.0 Hz
-500.0…500.0 Hz Frequency. 1 = 1 Hz
37.19 ULC frequency table
point 4
Defines the fourth frequency point.
See parameter 37.16 ULC frequency table point 1.
50.0 Hz
-500.0…500.0 Hz Frequency. 1 = 1 Hz
37.20 ULC frequency table
point 5
Defines the fifth frequency point.
See parameter 37.16 ULC frequency table point 1.
60.0 Hz
-500.0…500.0 Hz Frequency. 1 = 1 Hz
37.21 ULC underload point 1 Defines the first of the five points on the Y-axis that
together with the corresponding point on the X-axis (37.11
ULC speed table point 1… 37.15 ULC speed table point 5
or 37.15 ULC speed table point 5…37.15 ULC frequency
table point 5) define the underload (lower) curve.
The following conditions must be fulfilled:
• 37.21 ULC underload point 1 <= 37.31 ULC overload
point 1
• 37.22 ULC underload point 2 <= 37.32 ULC overload
point 2
• 37.23 ULC underload point 3 <= 37.33 ULC overload
point 3
• 37.24 ULC underload point 4 <= 37.34 ULC overload
point 4
• 37.25 ULC underload point 5 <= 37.35 ULC overload
point 5
10.0%
-1600.0…1600.0% Underload point. 1 = 1%
37.22 ULC underload point 2 Defines the second underload point.
See parameter 37.21 ULC underload point 1.
15.0%
-1600.0…1600.0% Underload point. 1 = 1%
