1. Verify that the tool is properly secured to the mounting plate, and that there are no signs of

stress or misalignment. Ensure that the socket is not engaged on a fastener and that

there is no tool movement while the self-check is being performed.

2. CHECk the spindle assembly to verify there are no worn bearings, and ensure there is no

binding or excessive prevailing torque.

3. Turn off the power. Verify the homerun cables are in good condition and are properly

connected to the Axis Unit and the tool.

4. ensure that the Main Unit and Axis Unit are not located near any strong electrical or

magnetic fields.

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

6. Turn on the power. If problem still exists, replace the tool cables with a known good set.

A spare set of cables is normally provided with each System.

7. If problem still exists, replace the affected tool. (Refer to Section 8.3)

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

9.4.4 Preset Data Abnormal (Axis Unit display code "A9")

The preset data for fastening is incorrectly set up.

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 previously 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.

15. Ensure that the Main Unit and Axis Unit(s) are not located near any strong electrical or

magnetic fields.
