Description
The drive generates a warning
warning) if the signal stays continuously above the overload
curve for half of the time defined by
timer.
The drive trips on 8002 ULC overload fault
continuously above the overload curve for the time defined
by 37.41 ULC overload
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
No action taken.

Drive trips on 8001 ULC underload
The drive generates a warning
warning) if the signal stays continuously below the
underload curve for half of the time defined by
underload timer.
The drive trips on 8001 ULC underload fault
stays continuously below the underload curve for the time
defined by 37.42 ULC underload
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.
