4.3  Executing a trail program run 
When testing a program, the system can interrupt the machining of the workpiece after each 
program block, which triggers a movement or auxiliary function on the machine. In this way, 
you can control the machining result block-by-block during the initial execution of a program 
on the machine.  
 
 
Note 
Settings for the automatic mode 
Rapid traverse reduction and dry run feed rate are available to run-in or to test a program.
