Maintenance and Diagnostics
Troubleshooting
Motion issues
• Motion is erratic.
• An axis “runs away”.
• No motion is observed.
• There is a high number of position errors.
• Parts may not be to tolerance.
Serial communication issues
• Processes and information communicated through the serial ports are not operating properly.
• P-S link fail messages are occurring.
• Unable to download files over a configured serial port.
• HPR-link fail messages are occurring when using serial communications to the HPR.
Using the serial port tester:
Note: This test only works with RS-422 configured ports. Refer to Utility and serial isolation board (141307) on
page 126 for information on how to determine whether the port is set up for RS-422.
1. In Phoenix, choose Setups > Diagnostics > Machine Interface > Enter the Machine password.
2. Test each of the serial port connectors on the back of the CNC by pressing one of the serial port connectors on the
touch screen and following the on-screen instructions.
3. If the test passes, verify that the ports are set up for RS-422 or RS-232, as needed by the external components
connected to the serial port.
4. If the test fails, replace the following items, one at a time and re-run the tests after each replacement:
a. Utility and serial isolation board (141307)
b. Ribbon cable (229245, 229459, or 229250)
The CNC is not recognizing a device in a USB port
1. In Phoenix, choose Setups > Diagnostics > Machine Interface > Enter Machine password or Setups >
Diagnostics > Operator Interface screens.
2. Press the USB port on the front panel or rear panel on the touch screen and follow the on-screen instructions.
3. If the test fails, re-run the test with a different USB memory stick.
4. If the test fails again, re-run the test using the other USB port (front or back).
5. If the test fails again, contact Technical Service. The problem is with the motherboard, the USB ports on the CNC or
the connection cables.
Cut quality or plasma performance issues
Press the “Cutting Tips” button on the Main screen and follow the on-screen instructions to improve cut quality.
The CNC feels excessively warm
1. Verify that the external fan is running. If it is running slowly, clean the fan.
2. If the fan is not running and ambient temperature is above 70° F (20° C):
a. Verify that the internal harness is connected from the fan to the Utility board.
b. Remove the fan shroud and verify that the connections to the fan are in place.
c. Replace the external fan (428007).
3. If the external fan is running and the CNC is still excessively warm, open the front door of the CNC and verify that the
internal fan is running. If the fan is not running, replace the internal fan (228474).
