Load Curve [41C]
The load curve function can be used with any smooth
load curve. The curve can be populated with a test-run
or the values can be entered or changed manually.
Load Curve 1-9 [41C1]-[41C9]
The measured load curve is based on 9 stored sam-
ples. The curve starts at minimum speed and ends at
maximum speed, the range in between is divided into 8
equal steps. The measured values of each sample are
displayed in [41C1] to [41C9] and can be adapted man-
ually. The value of the 1st sampled value on the load
curve is displayed.
