Parameters 339
Selects how the drive reacts if the absolute value of the
monitored signal stays below the underload curve for longer
than the value of
Disabled
No action taken.
0
Warning
The drive generates a warning (
).
1
Fault
Drive trips on
.
2
Warning/Fault
The drive generates a warning (
) if the signal stays continuously below the underload
curve for half of the time defined by
.
The drive trips on
if the signal stays
continuously below the underload curve for the time defined
by
.
3
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
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
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
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
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
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.

0.0 … 500.0 Hz
Frequency.
1 = 1 Hz
Defines the 2nd frequency point on the X-axis of the user load
curve.
25.0 Hz
0.0 … 500.0 Hz
Frequency.
1 = 1 Hz
Defines the 3rd frequency point on the X-axis of the user load
curve.
