Dialog Box 'CNC properties'

Symbol:

Function: This dialog box provides parameters for the CNC program object.

Call: Menu bar: View ‣ Properties ; context menu of the object.

Requirement: The CNC object is selected in the device tree.

Note

Application-specific CNC settings are saved in the CNC settings object.

Tab 'CNC'

Tab 'General'

Change the name of the CNC object.

Tab 'Access control'

Specify the permissions of the user groups.

Tab 'Build'

Activate the option to exclude the CNC object from the build. Then no IEC data is generated. However, it is possible to save the G code as an ASCII file. For reading this kind of file at runtime, you can use the function blocks from the SM3_CNC library.

Implementation	DIN66025: The motion path is defined in the DIN 66025 CNC language. Table: The motion path is defined by the parameterization of a table.
Compile mode	Behavior when compiling SMC_OutQueue: An SMC_OutQueue data structure is generated when compiling. You receive global access by g_CNCQueueManager. SMC_CNC_REF: Program variables are generated when compiling. You receive global access by g_CNCProgManager. File: A file generated by G code is downloaded and updated at each login. The PLC can download this file by means of function blocks. The G code files are updated each time at each login to the application. This meas that the files on the PLC are overwritten at each login.
File name	Requirement: Compile mode is File. Default: $ObjectName$.cnc. This default value represents a placeholder that is replaced by the object name of the CNC object (effective file name) at login. When you specify a file name, please note that only the characters [a-zA-Z0-9$_.] are permitted for file names. The field for the file name must not be blank or start or end with a dot. Moreover, a dot must not be part of the path in the file name.
Queue size	Default: 100. The size setting does not have any effect on the size of the generated SMC_OutQueue data structure (when this mode is selected). The size of SMC_OutQueue is determined by the number of path objects only. However, the parameter sets the buffer size of the preprocessing FBs (e.g. SMC_NCDecoder, SMC_RoundPath) which are used internally and define the size of the lookahead buffer.

Default values
Velocity (F) [u/s]	This value is used if the value if the velocity is not set (in the F word) in the CNC program. In path units per second. Value range: [0, 1e9]. Default: 0
Acceleration (E+) [u/s²]	This value is used if the value of the acceleration is not set (in the E word with positive value). In path units per second squared. Value range: ]0, 1e9]. Default: 100
Deceleration (E-) [u/s²]	This value is used if the value of the deceleration is not set (in the E word with negative value). In path units per second squared. Value range: ]0, 1e9]. Default: 100

Default values for positioning (G0)
Velocity (FF) [u/s]	This value is used if the value if the velocity is not set in rapid feed (in the FF word) in the CNC program. In path units per second. Value range: [0, 1e9]. Default: 0
Acceleration (EF+) [u/s²]	This value is used if the value of the acceleration in rapid feed is not set (in the EF+ word with positive value). In path units per second squared. Value range: [0, 1e9]. Default: 0
Deceleration (EF-) [u/s²]	This value is used if the value of the deceleration in rapid feed is not set (in the EF- word with negative value). In path units per second squared. Value range: [0, 1e9]. Default: 0

3D mode	Requirement: Implementation DIN 66025, translation mode CNC_REF, and OUTQueue : 3D mode is the default value.
Offline values of variables	Variables: If offline values are defined, then the Set variables dialog box opens. In this dialog, editable variables are displayed.
Start position	Default: 0
