Program start and program run
When the program test function is active, the part program can be started and executed (incl. auxiliary function
outputs, wait times, G function outputs etc.) via the interface signal:
DB21, ... DBX7.1 (NC-Start)
The safety functions such as software limit switch, working area limits continue to be valid.
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.
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.
Note
Dry run feedrate
"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.
Note
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.
