Glossary
Tool radius compensation
To directly program a desired → workpiece contour, the control must traverse an equistant
path to the programmed contour taking into account the radius of the tool that is being used

Transformation
Additive or absolute work offset of an axis.
Traversing range
The maximum permissible traversing range for linear axes is ± 9 decades. The absolute
value depends on the selected input and position control resolution and the unit of
measurement (inch or metric).
User interface
The menus and dialog boxes that the software displays on the monitor to aid the user in
operating a program. It features horizontal and vertical softkeys.
User memory
All programs and data, such as part programs, subroutines, comments, tool offsets, and zero
offsets/frames, as well as channel and program user data, can be stored in the shared CNC
user memory.
User program
User programs for the S7-300 automation systems are created using the programming
language STEP 7. The user program has a modular layout and consists of individual blocks.
The basic block types are:
● Code blocks
● Data blocks
User-defined variable
Users can declare their own variables for any purpose in the → part program or data block
(global user data). A definition contains a data type specification and the variable name. See
→ System variable.
Variable definition
A variable definition includes the specification of a data type and a variable name. The
variable names can be used to access the value of the variables.
