Cleaning the Code Tape
Significant contamination on code tapes can impair detection by the read head. Clean the code
tapes with isopropanol if necessary. If the contamination is severe, you can use a non-corrosive
plastic cleaner, e.g., Caramba
®
.
Angle Output
The read head detects the absolute angle in relation to the tracked lane with a maximum reso-
lution of 0.1
°
. The angle is specified as an absolute value relative to the tracked lane, as a Data
Matrix code tape contains 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

Absolute angle
Note
To avoid polishing the surface, do not apply strong pressure when cleaning. If the code tape
has a shiny surface, this impairs detection by the read head.
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
