Selection 
This function is selected via the operator interface in the "Program control" menu. 
This selection sets interface signal: 
DB21, ...DBX25.7 (program test selected). 
This does not activate the function.  
 
Activation 
The function is activated via interface signal: 
DB21, ... DBX1.7 (activate program test)  
 
Display 
As feedback that the program test is active, the appropriate field on the operator interface is 
reversed and interface signal: 
DB21, ... DBX33.7 (program test active) 
is set.  
 
 
Caution 
The signals for exact stop: 
DB31, ... DBX60.6/60.7 (exact stop coarse/fine) 
mirror the actual status on the machine.  
They are only canceled during program testing if the axis is pushed out of its set position (the 
set position remains constant during program testing). 
With signal: 
DB21, ... DBX33.7 (program test active) 
both the PLC program and the part program can use variable  
$P_ISTEST 
to decide how to react or branch in response to these signals during testing.  
Program execution without axis motion can also be activated with the function dry run 
feedrate. With this function, part program sections with a small programmed feedrate can be 
processed in a shorter time. 
 
 
Tool management 
Because of the axis disable, the assignment of a tool magazine is not changed during 
program testing. A PLC application must be used to ensure that the integrity of the data in 
the tool management system and the magazine is not corrupted. The toolbox diskettes 
contain an example of the basic PLC program.
