Program test

Several control functions are available for testing a new part program. These functions are
provided to reduce danger at the machine and time required for the test phase. Several
program functions can be activated at the same time to achieve a better result.
Test options
The following test options are described below:
● Program execution without setpoint outputs
● Program execution in singleblock mode
● Program execution with dry run feedrate
● Skip part program blocks
● Block search with or without calculation.

Program execution without setpoint outputs

Function
In the "Program test" status, a part program is executed without the output of axis or spindle
setpoints.
The user can use this to check the programmed axis positions and auxiliary function outputs
of a part program. This program simulation can also be used as an extended syntax check.
Selection
This function is selected via the operator interface in the "Program control" menu.
The selection sets the following interface signal:
DB21, ... DBX25.7 (program test selected)
This does not activate the function.
