COMPONENTS WITH POWER APPLIED.

9.4.13 input power over abnormal (axis Unit display code "d5, d6")

the input power exceeds specifications (200~230 VAC ± 10% , 50/60 Hz). When this error

message is displayed on the CRT, the corresponding Axis Unit display should be checked for

an Abnormal code. Refer to Section 9.6 for more information regarding this failure type.

D5/input voltage abnormal (high) errors

D6/input voltage abnormal (low) errors

1. ensure that the Axis Unit is not located near any strong electrical or magnetic fields.

2. Verify correct Axis Unit input voltage (3-phase).

3. Ensure that the power cable is in good condition and is properly connected.

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

9.4.14 Servo I/F power supply abnormal (axis Unit display code "a8")

the mEasured input power for the Servo (Axis Unit) interface has exceeded limits.

1. ensure that the Axis Unit is not located near any strong electrical or magnetic fields.

2. Verify correct Axis Unit input voltage and ensure the power cable is properly connected.

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

9.4.15 Servo type abnormal (axis Unit display code "a8")

the Servo (Axis Unit) type is not compatible with the configured and/or connected tool type.

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 the tool is connected to a compatible Axis Unit type. (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).
