9.3 Controller Error

WARNING:

DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM

COMPONENTS WITH POWER APPLIED.

9.3.1 Spindle Dual Port RAM Abnormal

An Axis Unit Dual Port RAM Error occurred while attempting communications between the

Axis Unit and the Main Unit.

1. Check the connected Axis Units for indications of abnormality. A locked-up display, an

illuminated Abnormal LED, and failure to count down are all possible indicators of a

malfunctioning Axis Unit. If all Axis Units appear to be functional, the problem is likely to

be found in another System component. Use the Axis Unit (if applicable) connected

directly to the Main Unit ribbon cable to perform the following inspections.

2. Turn off the power and verify the communication bus ribbon cable is in good condition and

is properly connected to both the Main Unit and the Axis Unit.

3. Remove the Main Unit Multi PCB, and verify the software is compatible with the Axis Unit

PCB. This may be of concern if a component has been replaced.

4. Verify correct installation of all removable IC chips on both the Axis Unit and Multi PCB.

5. Reinstall the Multi and Axis Unit PCBs, as necessary. Ensure that the boards are properly

seated.

6. Ensure that the Main Unit and Axis Unit are not located near any strong electrical or

magnetic fields.

7. Verify correct input voltages and ensure the power cables are properly connected.

8. Turn on the power. If problem persists, replace the Multi PCB. (Refer to Section 8.3)

9. If problem still exists, replace the affected AXIS UNit (if applicable). (Refer to Section 8.3)

10. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)

9.3.2 Preamp EEPROM Read Abnormal

Data error detected in the tool EEPROM information.

1. Check the connected Axis Units for indications of abnormality. A locked-up display, an

illuminated Abnormal LED, and failure to count down are all possible indicators of a

malfunctioning Axis Unit. If all Axis Units appear to be functional, the problem is likely to

be found in another System component. Use the Axis Unit (if applicable) connected

directly to the Main Unit ribbon cable to perform the following inspections.

2. Turn off the power and verify the communication bus ribbon cable is in good condition and

is properly connected to both the Main Unit and the Axis Unit.

3. Verify the homerun cable is in good condition and is properly connected to both the Axis

Unit and the tool (preamp / sensor).

4. Remove the Main Unit Multi PCB, and verify the software is compatible with the Axis Unit

PCB. This may be of concern if a component has been replaced.

5. Verify correct installation of all removable IC chips on both the Axis Unit and Multi PCB.
