Positioning direction
The positioning direction of the rotary axis to be measured is
determined from the start angle and the end angle that you define in
the cycle. Specify the start and end angles to ensure that the same
position is not measured twice. For example, a start angle of 0° and
end angle of 360° result in an error message.
As mentioned above, a duplicated point measurement (e.g. measuring
positions +90° und -270°) is not advisable because it can result in
different measuring positions, however it does not cause an error
message.
„ Example: start angle = -270°, end angle = +90°
The angular position would be identical but results in different
measured positions:
„ Start angle = +90°
„ End angle = -270°
„ No. of measuring points = 4
„ Angle step resulting from the calculation = (-270 - +90) / (4-1) =
-120°
„ Measuring point 1= +90°
„ Measuring point 2= -30°
„ Measuring point 3= -150°
„ Measuring point 4= -270°
