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