5.12 How To Proceed When Something Happens
5.12.1 How to Cancel a Cutting Program
1. Stop the machine movement and cutting by pressing TORCH ON/OFF or STOP BACKUP button.
2. Use the left mouse button to click the CANCEL PROGRAM button located at the top of the current job screen.
3. Wait until a new dialog box opens telling that the machine must return to 0,0-point. Click OK and machine runs back to 0,0-point
(original starting point of the cancelled program).
If you want to terminate the program during the rapid movement, the procedure is mainly the same. The only difference is that you stop the
machine using STOP BACKUP button instead of the TORCH ON/OFF.
5.12.2 Diffi culties While Piercing
NOTE
If the piercing fails in Plasma Mode, the machine will stop.
1. Adjust the speed slower with the SPEED knob if necessary.
2. Drive slowly backwards by pressing and holding STOP BACKUP and the machine will reverse on program path.
3. Stop the movement after passing the missed piercing point by releasing STOP BACKUP again.
4. Turn the speed back to 100%.
5. Start the program again by pressing MOVE AHEAD.
If the piercing fails at the fi rst prgrammed piercing point, the manchine runs using this prodedure backwards only to that piercing point and
stops. Start a new piercing with start delays by pressing TORCH ON?OFF.
Please notice that the movement backwards without cutting may be adjusted so that the speed is automatically reduced.
5.12.3 If the Cutting Fails
If the cutting is terminated e.g. for too high speed:
1. Stop the movement and cutting by pressing TORCH ON/OFF or STOP BACKUP.
2. Adjust the speed slower with the SPEED knob if necessary.
3. Drive slowly backwards by pressing and holding STOP BACKUP and the machine will reverse.
4. Stop the movement by releasing STOP BACKUP.
5. Turn the SPEED back to 100%.
6. Click on READJUST CUT PARAMETERS button on the Current Job screen.
7. Readjust cutting speed to a lower value by clicking inside the box and use the mouse wheel to enter new value and click OK.
8. Start the cutting delays and the cutting with TORCH ON/OFF. After the start delays, machine movement starts automatically.
9. Adjust the starting speed with the SPEED knob if required.
10. While cutting, the cutting speed can be easily readjusted by pressing the blue SPEED UP/DOWN buttons. Every short press increases
or decreases the speed about 1/2 ipm (10 mm/min).
