9.3.5 SELECTED SEQUENCE DOES NOT EXIST
<ERROR DESCRIPTION>
Sequence programs that are not entered as valid (preset) are being selected by an external
device (such as a PLC).
<CHECK ITEMS>
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. Ensure that a valid (preset) sequence number is being output to the ISA Main Controller.
4. ensure that the ISA Main Unit is not located near any strong electrical or magnetic fields.
5. Confirm that the ISA Main Unit input power remains constantly within specifications:
200~230 VAC +/- 10%, 50/60 Hz, single phase.
6. Verify that the ISA Main Unit power cable is free from damage and is properly connected.
7. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
9.3.6 SPINDLE COMMUNICATION I/F ABNORMAL
<ERROR DESCRIPTION>
The ISA Main Unit and the Axis Unit are unable to communicate.
<CHECK ITEMS>
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 both the MAIN UNIt and the AXIS UNIT.
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. Verify that all power cables are in good condition and are properly connected.
6. If the problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3.3)
7. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
9.3.7 PARAMETER SET ABNORMAL
<ERROR DESCRIPTION>
Fastening presets are set-up incorrectly.
<CHECK ITEMS>
1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER
screens match the physical machine configuration.
