ABB ACS880-x04, Firmware Manual

Page: 309 / 604

Parameters 309
Warning/Fault The drive generates a warning ( A8BE ULC overload warning )
if the signal stays continuously above the overload curve for
half of the time defined by
37.41 ULC overload timer .
The drive trips on 8002 ULC overload fault if the signal stays
continuously above the overload curve for the time defined by
37.41 ULC overload timer .
3
37.04 ULC underload
actions Selects how the drive reacts if the absolute value of the
monitored signal stays below the underload curve for longer
than the value of
37.42 ULC underload timer .
Disabled
Disabled No action taken. 0
Warning The drive generates a warning ( A8BF ULC underload
warning ).
1
Fault Drive trips on 8001 ULC underload fault . 2
Warning/Fault The drive generates a warning ( A8BF ULC underload
warning ) if the signal stays continuously below the underload
curve for half of the time defined by 37.42 ULC underload
timer .
The drive trips on 8001 ULC underload fault if the signal stays
continuously below the underload curve for the time defined
by
37.42 ULC underload timer .

37.11 ULC speed table
point 1 Defines the 1st speed point on the X-axis of the user load
curve.
The speed points are used in DTC motor control mode, and in
scalar motor control mode when speed control is being used.
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. 150.0 rpm
0.0 … 30000.0 rpm Speed. 1 = 1 rpm
37.12 ULC speed table
point 2 Defines the 2nd speed point on the X-axis of the user load
curve. 750.0 rpm
0.0 … 30000.0 rpm Speed. 1 = 1 rpm
37.13 ULC speed table
point 3 Defines the 3rd speed point on the X-axis of the user load
curve. 1290.0 rpm
0.0 … 30000.0 rpm Speed. 1 = 1 rpm
37.14 ULC speed table
point 4 Defines the 4th speed point on the X-axis of the user load
curve. 1500.0 rpm
0.0 … 30000.0 rpm Speed. 1 = 1 rpm
37.15 ULC speed table
point 5 Defines the 5th speed point on the X-axis of the user load
curve. 1800.0 rpm
0.0 … 30000.0 rpm Speed. 1 = 1 rpm
37.16 ULC frequency
table point 1 Defines the 1st frequency point on the X-axis of the user load
curve.
The frequency points are used in scalar motor control mode
when frequency control is being used.
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
0.0 … 500.0 Hz Frequency. 1 = 1 Hz
No. Name/Value Description Def / FbEq16
