User load curve

The user can specify a load curve (motor torque as a function of frequency) for
supervision. The curve is defined by five points. Supervision can be set for the torque
dropping below the underload curve, exceeding the overload curve, or both.
A fault is generated if the torque has been out of the allowed area for longer than the
user-defined time limit. An alarm is generated if the torque has been out of the
allowed area for longer than the half of the user-defined time limit.
