Program test

You can test a part program using three different methods before machining pieces.
Testing the program with dry run
With dry run, all programmed motion commands are replaced by a defined dry run feedrate (refer to Section "Setting the
JOG data (Page 204)"). Before executing the dry run, first remove the workpiece from the machine.
Proceed as follows to test a part program with dry run.

Each block is decoded separately, and a stop is performed at each block. However, for the thread

Performs program test before real machining by checking the axis movement on the machine. It
disables the output of setpoints to spindles and suppresses all auxiliary functions.
After activating this option, the icon "AFL" appears immediately in the program status bar and this
softkey is highlighted in blue.
Note that the display is toggled between "AFL" and "PRT" by pressing the corresponding softkey.

5. Press this key on the MCP to close the door in the machine (if you do not use this function,
just close the door in the machine manually).
6. Make sure the feedrate override is 0%. Check that correct tool is in spindle before continu-
ing.
7. Press this key on the MCP to run the program.
