4.7 Basic parameterization of the drive objects
Define characteristic curve
The scaling specifies the processing of the measured signal. This requires the definition of a
straight line with two points.
1. Click the "Scaling" button in the adjustment range of a measuring socket.
The "Scaling CU320 measuring socket Tx" dialog opens. You can define the values of a
characteristic curve in this dialog.
Figure 4-70
2. In the dialog, select individual values within their defined limits, which are displayed in the
relevant tooltips.
– Value X1 (p0777)
– Value X2 (p0779)
– Value Y1 (p0778)
– Value Y2 (p0780)
Example: x1/y1 = 0%/2.49 V x2/y2 = 100%/4.98 V
– 0.0% is mapped to 2.49 V
– 100.0% is mapped to 4.98 V
– -100.0% is mapped to 0.00 V
3. Confirm your entries with "OK".
