Angle Output
Note!
Angles are specified as absolute values. The respective value is calculated from the resolution
selected under "Angle Resolution". With a resolution of 0.1°, an angle of 60° is output as
60°/0.1° = 600.
The read head detects a change of the angle of the colored tape and the Data Matrix code tape
and outputs this value to the controller. The output value is different for colored tapes and Data
Matrix code tapes.
Colored tape
The read head detects the angle in relation to the tracked lane with a resolution of 360
(corresponds to 1°). The angle is specified relative to the tracked lane because a colored tape
does not include any direction information. The output angle covers the range from -45° to 45°.
The resolution is 1°.
Figure 5.5
Data Matrix code tape
The read head detects the absolute angle in relation to the tracked lane with a maximum
resolution of 0.1°. The angle is specified absolutely relative to the tracked lane, since a Data
Matrix code contains tape direction information. The output angle covers the range from 0° to
360°. The resolution can be set to the following values:
0.1°
0.2°
0.5°
1°
