D5/input voltage abnormal (high) errors

D6/input voltage abnormal (low) errors

1. Ensure that the Axis Unit is not located near any strong electrical or magnetic fields.

2. Verify Axis Unit input voltage and ensure that the power cable is properly connected.

3. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

9.4.14 Servo I/F Power Supply Abnormal (Axis Unit display code "A8")

The measured input power for the servo interface has exceeded limits.

1. Ensure that the Axis Unit is not located near any strong electrical or magnetic fields.

2. Verify correct Axis Unit input voltage and ensure the power cable is properly connected.

3. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

9.4.15 Servo Type Abnormal (Axis Unit display code "A8")

The Servo (Axis Unit) type is not compatible with the configured and/or connected tool type.

1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER

screens match the physical machine configuration.

2. Re-enter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET

PARAMETER screens or reload the Preset files from the PRESET FILE UTILITY screen.

3. 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 (Refer to Step 4). If some Axis Units appear to be

funtional, use an affected (abnormal) Axis Unit to perform the following inspections,

beginning with Step 12.

4. If all Axis Units appear to be affected, turn off the power. Remove the FC386 and Multi

PCBs from the Main Unit, and verify compatibility of software between the two (2) circuit

boards. This may be of concern if a board has been replaced.

5. Verify correct installation of all removable IC chips on both the FC386 and Multi PCBs.

6. Reinstall the FC386 and Multi PCBs. Ensure that the boards are properly seated.

7. Ensure that the Main Unit is not located near any strong electrical or magnetic fields.

8. Verify the Main Unit input voltage and ensure that the power cable is properly connected.

9. Turn on the main 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 one or some of the spindles (Axis Units), 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 PCBs. Ensure that the boards are properly seated.
