Line Speed Detection Setup - Linx 5900 Manual

How To Install and Set Up the 5900 &
7900 Printer

3 Line speed detection setup

Linx recommends that you use a shaft encoder or dual trigger to detect the line speed on
production lines where the speed can change. If your system has a fixed line speed, you can
go to the next section.
The shaft encoder generates a pulse for a fixed distance of product movement. The pulses
enable the printer to print at a constant width if the line speed changes.
For information about setting the line speed, see How To Change the System Setup.
Normally the shaft encoder is attached to a drive shaft on the production line. Install the
shaft encoder in the best position to follow the movement of the products.
Linx offers the following range of shaft encoders for line speed detection:
•
2500 pulses per revolution (p.p.r.)
•
5000 p.p.r.
•
10000 p.p.r.
Each shaft encoder has a 5-metre cable fitted with a 9-pin D-type connector.
To measure the line speed, you can connect the shaft encoder to a drive shaft on the line, or
to an encoder wheel. Linx provides the following range of encoder wheels:
•
500 mm circumference
•
333 mm circumference
•
304.8 mm (1 foot) circumference
•
200 mm circumference
•
60 mm circumference
