9. Turn on the power. If problem still exists, replace the Multi PCB. (Refer to Section 8.3)
10. If problem still exists, replace the FC386 PCB. (Refer to Section 8.3)
11. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)
12. If the problem only affects a single spindle, remove an affected Axis Unit PCB and the
Main Unit Multi PCB. Verify compatibility of software between the two (2) Units. This may
be of concern if a board or Unit has been replaced.
13. Verify correct installation of all removable IC chips on both the Axis Unit and Multi PCB.
14. Reinstall the Axis Unit and Multi PCB. Ensure that the boards are properly seated.
15. Ensure that the Main Unit and the Axis Unit(s) are not located near any strong electrical
or magnetic fields.
16. Verify correct Axis Unit input voltage and ensure the power cable is properly connected.
17. Turn on the power. If problem still exists, replace the affected AXIS UNit. (Refer to
Section 8.3)
18. If problem still exists, replace the entire tool. (Refer to Section 8.3)
9.4.12 Dual Port RAM Abnormal (No Axis Unit display code)
<ERROR DESCRIPTION>
An Axis Unit DUAL PORt RAM error occurred while attempting communications between the
AXIS UNIt and the Main Unit.
<CHECK ITEMS>
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 suspected Axis Unit PCB and Main Unit Multi PCB. Verify compatibility of
software between the two (2) units. This may be of concern if a board has been replaced.
4. Verify correct installation of all removable IC chips on both the Axis Unit and Multi PCBs.
5. Reinstall the Axis Unit and Multi PCBs. 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 Axis Unit input voltage and ensure the power cable is properly connected.
8. Turn on the power. If problem still exists, replace the Multi PCB. (Refer to Section 8.3)
9. If problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3)
10. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)
9.4.13 Input Power Over Abnormal (Axis Unit display code "d5, d6")
<ERROR DESCRIPTION>
The measurement of input power exceeds the set limit of 200~230 VAC ± 10% (180~253V).
When this error message is displayed on the CRT, the corresponding Axis Unit display should
be checked for an Abnormal code. Refer to Section 9.6 for more information regarding this
failure type.
