9.3.1 SPINDLE DUAL PORT RAM ABNORMAL
The System is sensing a Dual Port Ram Abnormal in an Axis Unit which is unable to
communicate with 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 ISA Main and Axis Units are not located near any strong electrical or
magnetic fields.
4. 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).
5. Ensure that all power cables are in good condition and are properly connected.
6. If the problem persists, replace the affected AXIS UNit. (Refer to Section 8.3.3)
7. If the problem still exists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
9.3.2 PREAMP EEPROM READ ABNORMAL
A dAta error was detected in the tool EEPROM information.
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 UNIt and the AXIS UNIT.
3. Verify that the homerun cable is in good condition and is properly connected to both the
Axis Unit and the tool (preamp / sensor).
4. ensure that the ISA Main Unit and the Axis Unit are not located near any strong electrical
or magnetic fields.
