Reading table values with TABDATA READ
Application
The function TABDATA READ allows you to read a value from a table and save it to a variable.
For example, the TABDATA READ function enables you to pre-check the data of the tool to be used to prevent error messages from occurring during program run.
Description of function
Depending on the type of column you want to transfer, you can use numerical or string parameters to save the value. The control automatically converts the table values to the unit of measure used in the NC program.
Input
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
