After turning on the labeler, the input signals are scanned to start a labeling
cycle.
The dispensing of a label is triggered by the negative edge of GSC (Goods
scanner input). The stop of the labelling is triggered by the detection of the
gap (LSC) and performing the remaining steps for the predispensing.
The timing diagram of the signals is shown in Figure 14:
1. Length of the predispensing
If the signal FEED is active the motor is turning. The FEED signal has no
electrical tabs on the Collamat 2600 terminals.
If the predispensing is increased, it is executed immediately. If it is reduced,
it is executed after dispensing the next label.
To generate the holding torque, the motor is powered all the time.
If, for any reason, no negative edge is detected on the LSC-input, the label-
web is automatically stopped after approximately 0.75 meters.
The stepper motor is driven by a sinusoidal corrent figure.
The minimum speed is 3 m/min. The maximum speed is 15 m/min.
