Reading a table value

The function TABDATA READ allows you to read a value from a table
and save it to a Q parameter.
Depending on the type of column you want to transfer, you can use
Q, QL, QR, or QS to save the value. The control will automatically
convert the table values to the unit of measure used in the NC
program.
The control reads from the tool table that is currently active. You can
read a value from a compensation table only if you have activated
the table concerned.
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.
