User-definable load curve
The drive output can be limited by defining a load curve. In practice, the user load
curve consists of an overload and an underload curve, even though neither is
compulsory. Each curve is formed by five points that represent output current or
torque as a function of frequency.
An alarm or fault can be set up to occur when the curve is exceeded. The upper
boundary (overload curve) can also be used as a torque or current limiter.
