Chapter 5 Operator Interface
There are two ways to enter the label pitch and stop distance for the
Label‑Teach operation:
Option 1.
Measure label pitch ( gap) and stop distance and enter as param‑
eters using the terminal. Note: All values are in motor steps.
Option 2.
Place label web with manual function to the dispensing position. Then
activate the LABEL_TEACH to start teach in procedure (Note: motor
moves with the low jog speed).
While setting up the labeling machine, the JOG operation is
required to move the label to the correct position at the peel
plate. The LABEL‑TEACH learning movement function is
used to determine the manually adjusted operating position
for the AUTOMATIC OPERATION.
The LABEL‑TEACH learning movement is started by se‑
lection LABEL‑TEACH in the main menu. The function
advances the web 3‑4 label lengths with the manual low
speed.
With the digital input LABEL_SENS a total of 3 label lengths
including the gaps between the labels are measured and the
average length of the 3 label lengths is then calculated as
a set value (LABEL PITCH) then later used in the actual
labeling operations.
Problems with the adjustment of the label sensor or with label web itself
can be detected with the learning movement. It is required to move the
label sensor further away from the label edge if the sensor is placed just
at the label end after a learning movement, because this is a disadvanta‑
geous position for the automatic operation.
Only after an error free LABEL‑TEACH learning movement all the
measuring results are accepted by the controller and saved as operating
parameters permanently to EEPROM.
1. The label pitch ( pitch = label gap between labels)
2. The stop distance after detecting a label end signal.
