Distance measurement Use the parameters of the Distance measurement group to assign the settings of the exter-

nal sensor for the distance measurement.

Dynamic focus Use the parameters of the Dynamic focus group to assign the values and the behaviour of

the dynamic control mode.

Parameters Function

Behaviour Select time of focus position switching:

! IMMEDIATE: Focus is continuously re-adjusted

! LATCHED: First focus value is retained for the entire reading cy-

cle

Pre-expansion Enter value by which the distance measurement is expanded

against the X direction (conveyor direction).

If applicable, select unit.

The signal of the external sensor is then impressed earlier.

Post-expansion Enter value by which the distance measurement is expanded in

the X direction (conveyor direction).

If applicable, select unit.

The signal of the external sensor is then applied longer.

Preferred distance Select the focus position at the start of the reading cycle:

! DEFAULT FOCUS POSITION: Focus is always reset to default

! DISTANCE OF LAST OBJECT: Focus remains at the distance of the

last object

Focus hysteresis Enter threshold for focus position switching.

If applicable, select unit.

Parameters Function

Dynamic control mode Select whether the focus position is switched via a control signal

or at regular time intervals.

Timer Enter the time after which switching to the next focus position

value occurs.

Dynamic distance configura-

tions

Enter up to eight fixed values for the focus position.

Order of dynamic distance con-

figuration

The eight values ("1" to "8") for the focus position are set in the

displayed order.

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 41 42
