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.
5. 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).
6. Ensure that all power cables are in good condition and are properly connected.
7. If the problem still exists, replace the tool (homerun) cables with a set that is known to be
good. A spare cable set is normally provided with each System. (Refer to Section 8.3.5)
8. If the problem still exists, replace the affected tool. (Refer to Section 8.3.4)
9. If the problem persists, replace the affected AXIS UNit. (Refer to Section 8.3.3)
10. If the problem is still not corrected, replace the entire Main Unit. (Refer to Section 8.3.1)
WARNING:
DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM
COMPONENTS WITH POWER APPLIED.
9.3.3 PRESET SPINDLE DOES NOT EXIST
<ERROR DESCRIPTION>
This Abnormal will typically output when either the System Preset spindle number does not
match the connected Axis Unit's spindle number dip switch setting, or the System cannot
sense the Axis Unit due to an improper communication ribbon cable connection.
<CHECK ITEMS>
1. Verify that the communication bus ribbon cable is in good condition and is properly
connected to the ISA Main and Axis Units.
2. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER
screens match the physical machine configuration.
3. Re-enter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET
PARAMETER screens (or reload the Preset files from the PRESET FILE UTILITY
screen).
4. ensure that the ISA Main and Axis Units are not located near any strong electrical or
magnetic fields.
5. 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).
6. Verify the Axis Unit spindle number dip switch setup. (Refer to Section 4.9)
7. If problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3.3)
8. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
9.3.4 CONTROLLER EEPROM WRITE ABNORMAL
<ERROR DESCRIPTION>
DAta write error occurred while communicating to the Multi2 PCB EEPROM.
<CHECK ITEMS>
1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER
screens match the physical machine configuration.
