Starting The job list or start program must be selected and executed with NC
Start. The required execution times for the individual instructions are
added to the times per step and saved within the control.
Displaying time proportional
steps for multiple channels
Edit
workpiece
The multi-channel program display is opened when you press the
"Edit workpiece" softkey once the above listed preparations have
been completed.
Evaluation and optimization Reposition the steps or synchronization points (WAITM()) so that
multi-channel execution leads to better parallelness and therefore
shorter workpiece processing times.
Other information
After making changes to the program, you need to process the
workpiece again to compute the new times.
Programs which have been modified are marked with a red X until the
times have been updated.
If no time computation was performed, all steps in the program are
displayed with equal time lengths.
The computed times are saved in a .DAT file for each workpiece. The
file is compressed when the step editor is exited.
Multi-channel views There are 3 views:
- Standard view, all steps are the same length
- Time proportional steps
- Synchronized display
Synchronized display is possible without having performed the time
computation.
