Description
Selects an action taken if the signal (
under the underload curve for a defined time.
No warnings or fault generated.
The drive generates an
if the signal has been continuously under the
underload curve for a time defined by parameter
37.42 ULC underload timer
8001 ULC underload fault
The drive trips on
signal has been continuously under the underload
curve for a time defined by parameter
underload timer
.
The drive generates an
if the signal has been continuously under the
underload curve for half of the time defined by
37.42 ULC underload timer
parameter
8001 ULC underload fault
The drive trips on
signal has been continuously under the underload
curve for a time defined by parameter
underload timer
.
Defines the first of the five speed points on the X-axis
of the user load curve.
The values of the parameters must satisfy: -
37.11 ULC speed table point 1
30000.0 rpm <
ULC speed table point 2
3 37.14 ULC speed table point 4
<
table point 5
< 30000.0 rpm.
Speed points are used if parameter
control mode
is set to
mode Scalar
is set to and the reference unit is rpm.
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.
