3.1 Test Run
In the TEST RUN mode of operation the TNC checks programs and
program sections for the following errors (without moving the machine
axes):
• Geometrical incompatibilities
• Missing information
• Impossible jumps
• Violation of the machine's working space
The following functions can be used in the TEST RUN operating mode:
• Blockwise test run
• Interrupt test at any block
• Block skip
• Blockwise transfer of very long programs from external storage media
• Graphic simulation
• Measurement of machining time
• Additional status display
To run a program test:
• If the central tool file is active, the tool table with which the program test is to be run must have status S
(see page 1-31).
• With the MOD function DATUM SET, you can activate work space monitoring for the test run (see page 10-6).
