Direction-dependent traversing motion disable

Syntax
$A_OUT[
Number
Number of the parameterized digital output (see below: Parameterization)
• Format: Integer
• Range of values: 1, 2, . . . max. number of digital outputs
Enabling signal
Enabling signal, can be inverted (see below: Parameterization)
• Format: Integer
• Range of values: 0, 1
System variable $A_OUT[n] can be set block-synchronously in the part program or
asynchronously via synchronized actions.
Functionality
Parameterizable digital outputs (system variable $A_OUT) can be used for direction-
dependent disabling of the traversing motion (manipulated variable) induced via clearance
control. As long as e.g. the negative traversing direction is disabled, the clearance-controlled
axes will only travel in a positive direction due to the sensor signal.
This can be used for example when laser-cutting sheet steel to "skip over" sections of sheet
that are not to be machined without foundering.
