8.3.3 APSF sensor
For the APSF function (Automatic speed follower) a rotary encoder has to be installed. For
optimum labelling accuracy the rotary encoder should be selected so that it produces one pulse
for every 0.125 mm of product movement. The connection of the encoder should be done with
a shielded cable. For correct operation the rise and fall time of the encoder signal should be
1 µs.
