1. Check the connected Axis Units for any abnormal indications. If all spindles appear to be

affected, the problem may be a result of some common item.

2. If the problem appears to be a common fault, verify correct input power to the Axis Units.

3. Turn off the power. Verify that the homerun cables are in good condition and are properly

connected to the Axis Unit and the tool.

4. Ensure that the Main Unit and Axis Unit are not located near any strong electrical or

magnetic fields.

5. If the problem only affects a single spindle, verify correct Axis Unit input voltage and

ensure that the power cable is properly connected.

6. Turn on the power. If problem still exists, exchange the tool cables with a known good set.

A spare set of cables is normally provided with each system.

7. If problem still exists, replace the affected tool. (Refer to Section 8.3)

8. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

9.4.8 Servo Alarm (Axis Unit display code "d0, d1, d3, d7")

An error has been detected in the Servo Drive portion of the Axis Unit. When this error

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

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

D3 - Servo Overtemp

1. Check the SET PARAMETER screens and verify that the settings do not result in a Duty

Cycle higher than 50%, and that the resultant Cycle Time is not less than 12 seconds.

2. Check the connected Axis Units for any abnormal indications. If all spindles appear to be

affected, the problem is likely to be found in another System component.

3. If the problem appears to be a common fault, verify correct input power to the Axis Units.

4. if the problem only affects a single spindle, check the affected spindle for binding and

excessive prevailing torque. If either condition is found, isolate and correct the cause.

5. If no binding or excessive prevailing torque is found, verify correct Axis Unit input voltage

and ensure that the power cable is properly connected.

6. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

7. If problem still exists, replace the affected tool. (Refer to Section 8.3)

Note: Abnormal will not clear until the affected Unit cools down

D0 - Encoder Connection

1. Check the connected Axis Units for any abnormal indications. If all spindles appear to be

affected, the problem may be a result of some common item.

2. If the problem appears to be a common fault, verify correct input power to the Axis Units.
