3.1.2 ParametersParameter sets are assigned to every message and offer the possibility to adapt the laserparameters to your product. The parameters depend on the material of your product and onthe desired marking quality. The parameter sets are adjusted to specific materials or products,e.g. paper or synthetic material. In this menu you can change the name of a parameter set oredit the following values:

Laser Parameters

Filling Parameters

Vector Length

Mark Speed defines the speed of movement of the laser beam when marking theproduct.

Jump Speed defines the speed of movement of the laser beam when moving from onestroke to the next. The laser is switched off during a jump. A typical valueis 20000 mm/s.

Jump Delay defines the delay between the end of a jump and the start of the markingprocess.

Mark Delay defines the delay between the marking of individual vectors within astroke.

Stroke Delay defines the delay between the end of a stroke and the jump to the nextstroke.

Laser Power sets the output power via the current value (with 100 % corresponding tothe maximum power of the laser).

On-Delay defines the delay between the attainment of the start position of a strokeand the switching-on of the laser.

Off-Delay defines the delay between the attainment of the end position of a strokeand the switching-off of the laser.

Pulse Frequency

can be set between 50 Hz and 20 kHz. Low values can be used toachieve a broken line.

Line width defines the actual line width for e.g. barcodes on the product. This param-eter highly depends on the material and is defined by measuring the linewidth on the product.

Overlap defines whether two adjacent lines overlap each other (positive values) orif there is a certain distance between two adjacent lines (negative values).This parameter refers to the entered line width and is stated in percent.

Min. vector defines the minimum length of a vector. Shorter vectors are not marked.

Max. vector defines the maximum length of a vector. Longer vectors are divided intoshorter vectors.

02/06 - Rev. AB 17


3.1.3 Product RegistrationHere you can define whether the product is moving during the marking process, how this move-ment shall be detected, how the triggers are set, etc. These settings are combined in a productregistration and - like the parameter set - assigned to a message.

Product MovementThe following types of product movement can be selected:• No product movement

• Fixed speed

• Encoder (no monitoring of rotational direction)

• Directional encoder (monitoring of rotational direction)

The available entries depend on the type of product movement (e.g. if there is no movementthere is no speed to be defined). In the following all possible entries are listed.

AngleTo compensate for the product movement during the marking process the angle between themarking head of the laser system and the direction of product movement has to be defined.

Dist./Rot.This value defines the distance the product covers with one full turn of the incremental encoder.

Pulse/Rot.This value states the number of pulses the incremental encoder emits when performing one fullturn.

SpeedValue in mm/s to define a fixed speed for the product movement.

DirectionIf a directional encoder is used for detecting the product movement you can define its rotationaldirection: clockwise or counterclockwise.

18 02/06 - Rev. AB


TriggersThere are different settings for the registration of product movement. The triggers are subdivid-ed into »Start Trigger« and »Next Trigger« and »Stop Trigger«. The availability of the individualtrigger settings depends on the selected trigger type and the product movement.

»Start Trigger« defines the settings for the first trigger pulse. The marking process is startedby the first trigger pulse.With the trigger set to »Auto«, the marking process is started by pressing START on the con-trol panel of the laser system.To start the marking process by an external signal an input channel can be selected. For thechannel you can select whether the rising or the falling edge is to be used as trigger.

»Start Delay« defines the distance until the marking process is started, which is the distancebetween the center of the marking field of the laser system and the center of the marking onthe product. After the trigger the product has to cover this distance before is in front of the mark-ing head. If »No product movement« has been selected the start delay defines the time be-tween start trigger pulse and marking in ms.

»Next Trigger« defines the settings for all trigger pulses following the start trigger pulse. If thenext trigger is set to »None«, only the start trigger pulse starts a marking process. All followingtrigger pulses are not accepted. Select »None« whenever you want to generate a single mark-ing.With the next trigger set to »Auto«, the marking process is triggered internally and continu-ously. The marking process is repeated with a certain frequency or after the product has cov-ered a certain distance - depending on the settings for the product movement.The marking process can be triggered by an external trigger signal. For the channel you canselect whether the rising or the falling edge is to be used as trigger.

»Blocking« defines the distance the product has to cover before the next marking can be start-ed. If »No product movement« has been selected the blocking defines the time that has to passafter a start trigger until a next trigger is accepted.

»Stop Trigger« defines the settings for a trigger pulse that stops the marking process (e.g.the end of a cable or a stop signal from an external control unit). The laser system remainsready to mark after a stop trigger pulse, which means that the marking process will be contin-ued if another start trigger pulse is detected.If the trigger is set to »None«, only the start trigger pulse starts a marking process. All follow-ing trigger pulses are not accepted.To stop the marking process by an external signal an input channel can be selected. For thechannel you can select whether the rising or the falling edge is to be used as trigger.

»Stop Blocking« sets the blocking time after the stop trigger pulse, where no external triggerpulses are accepted (debouncing).
