Traversing range
The maximum permissible travel 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 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
These blocks contain the STEP 7 commands.
• Data blocks
These blocks contain constants and variables for the STEP 7 program.
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.
Velocity control
In order to achieve an acceptable traverse rate in the case of very slight motions per block, an anticipatory
evaluation over several blocks ( → Look Ahead) can be specified.
WinSCP
WinSCP is a freely available open source program for Windows for the transfer of files.
Working area
Three-dimensional zone into which the tool tip can be moved on account of the physical design of the machine
tool. See → Protection zone.
