Operation and communication
When the read head enters the range of a control code, it sets the control code flag in its output
data.
The 1-meter-long control code can be shortened. However, the minimum length should be 3
codes (60 mm). If the speed of the read head increases, a longer control code is required. If the
read head travels at maximum speed, a full-length control code of 1 meter must be positioned
next to the colored tape or code tape for positioning.
The minimum length of a control code can be calculated according to the following formula
depending on the travel speed and trigger period:
L
control code
The trigger period is 40 ms.
Example!
Example calculation
The minimum length of the control code at a speed of 3 m/s and a trigger period of 40 ms is:
L
Event marker
Control codes are identified by the printed number, in this case "Control 12".

The illustration shows part of control code #12
Refer to the "Accessories" chapter for order information relating to control codes.

Operation Using Repair Tape
The repair tape is a short code tape one meter in length. The repair tape is used to bridge
defective or damaged areas of an existing code tape.
1. Cut the repair tape to the required length
2. Cover the defective area of the existing code tape with the repair tape
Note!
When placing a repair tape on the code tape, make sure that the repair tape continues the
pattern on the code tape as accurately as possible.
When the read head enters the range of a repair tape, it sets the repair tape flag in its output
data.
Note!
The repair tape works incrementally. In so doing, it adds one value to the previous read position
on the code tape. If the read head starts on a repair tape, the read head reports an error. Move
the read head to a position on the code tape away from the repair tape to read the absolute
value.
