WARNING:

DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM

COMPONENTS WITH POWER APPLIED.

9.4.11 tOOL TYPE MISMATCH ABNORMAL (axis Unit display code "a3")

PRESet tool type and connected tool type are mismatched.

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. Verify that the Axis Unit and connected tool type are compatible. (Refer to Section 2.4)

4. Check the connected Axis Unit(s) 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. In that case, use the Axis Unit connected directly

to the ISA Main Unit ribbon cable to perform the following checks.

5. Verify that the communication bus ribbon cable is in good condition and is properly

connected to both the ISA MAIN UNIt and the AXIS UNIT.

6. ensure that the ISA Main and Axis Units are not located near any strong electrical or

magnetic fields.

7. Verify that the input power specifications (200~230 VAC +/- 10%, 50/60 Hz) are met for

both the Axis Unit (3-phase) and the ISA Main Unit (single phase).

8. Verify that all power cables are in good condition and are properly connected.

9. If the problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3.3)

10. If the problem persists, replace the affected tool. (Refer to Section 8.3.4)

9.4.12 DUAL PORT RAM ABNORMAL (no axis Unit display code)

An Axis Unit DUAL PORt RAM error occurred while attempting communications between the

AXIS UNIt and the ISA MAIN UNIT.

1. Check the connected Axis Unit(s) 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. In that case, use the Axis Unit connected directly

to the ISA Main Unit ribbon cable to perform the following checks.

2. Verify that the communication bus ribbon cable is in good condition and is properly

connected to the ISA MAIN and AXIS UNITs.

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

magnetic fields.

4. Verify correct Axis Unit input voltage and ensure that the power cable is properly

connected.

5. If the problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3.3)

6. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
