Object 'CNC Settings'

Symbol:

The settings in this object are valid for all CNC objects of the application. The object is added to the device tree of the application or it is generated automatically when a CNC object is added to the application. The object can exist only one time per application and cannot be renamed. In the editor of the object, settings can be specified for the path preprocessing modules, preinterpolation, and CNC table editor. You can delete the CNC settings object only if no CNC object exists below the application.

Note

Settings that are valid only for a specific CNC program are saved in the Settings dialog of the CNC program.

Tab 'Path preprocessors'

Tab 'Table editor'

Tab 'Path preprocessors'

In this tab, path preprocessing programmed by selecting function blocks.

Available function blocks	List of all available function blocks
Active function block instances	List of the selected function block instances The position in the list defines the processing order and can be changed. A function block can be instantiated in the list multiple times.
Parameter	Opens the dialog box Parameter editor for <selected active function block instance>. Alternative: Double-click an active function block instance.
	Adds an instance of the function block to the Active function block instances that is selected in Active function block instances.
	Deletes the selected function block instance. Function block instances of function blocks, which are displayed in light-gray italics, cannot be deleted.
	Moves the selected active function block instance upwards by one line. Alternative: Press Shift+Arrow up.
	Moves the selected active function block instance downwards by one line. Alternative: Press Shift+Arrow down.

Dialog box Parameter editor for <selected active function block instance>.

This dialog box is used for displaying and changing the entries of the selected instance. Not all inputs are visible.
Column1	Name of the parameter of the selected active function block instance
Column2	Drop-down list for setting the value
Column3	Description of the parameter

Tab 'Preinterpolation'

Cycle time µs

Interpolation time

Initial value: 20000

Velocity mode

Trapezoid: Velocity profile with trapezoidal shape

Sigmoidal: Velocity profile like the trapezoidal profile but with sin² functions that replace the linear velocity ramp

Sigmoid limited: Velocity profile like the sigmoidal profile but with consideration of the limits for acceleration and deceleration

Quadratic: Acceleration profile with trapezoidal shape with jerk limitation as defined in Maximum jerk. The resulting quadratic velocity profile is also recognized as an S curve.

Quadratic (smooth): Works like Quadratic mode but generates a jerk profile without jumps.

Maximum jerk [u/s³ ]

Limitation of the absolute value of the jerk

Used for quadratic velocity profile only.

Notice

The interpolation time and cycle time of the respective task, in which the interpolator is called, must match for identical behavior of the CNC editor and online application.

Tab 'Table editor'

In this tab, the columns of the table editor and its order are defined.

Table columns

List of all available attributes

: Attribute is visible in the table editor

The order in this list determines the line order in the table editor.

Moves the selected attribute upwards by one line.

Moves the selected attribute downwards by one line.
