Parameters 231
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.
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 frequency table
point 5 or 37.15 ULC speed table point 5…37.20 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%
37.23 ULC underload point 3 Defines the third underload point.
