2.4 Program test
Testing part programs
Purpose
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.
2.4.1 Program execution without setpoint outputs
Functionality
In the "Program test" status, a part program is executed without the output of axis or spindle
setpoints.
The parts porgram in the active program test function through the interface signal:
DB21, ... DBX7.1 (NC start)
can be started and processes,
i.e., by means of auxiliary function outputs, wait times, G function outputs etc.
The safety functions such as software limit switch, working area limits continue to be valid.
No axis motion
The only difference compared to normal program operation is that an internal axis disable is
set for all axes (including spindles). The machine axes do not move, the actual values are
generated internally from the setpoints that are not output. The programmed velocities
remain unchanged. This means that the position and velocity information on the operator
interface is exactly the same as that output during normal part program execution.
The position control is not interrupted when this function is active, so the axes do not have to
be referenced when the function is switched off.
