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 the problem still exists, replace the affected Axis Unit. (Refer to Section 8.3.3)
7. If the problem still persists, replace the affected tool. (Refer to Section 8.3.4)
D0 - Encoder Connection (Abnormal will not clear until the problem is corrected):
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. if the problem only affects a single spindle, perform an encoder test procedure as provided
in Section 8.2.2.
4. If the encoder test identifies a problem, then exchange the tool, cables, and/or the Axis
Unit until the cause of the problem is identified.
5. If the encoder test does not identify a problem, verify the 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 8.3.3)
7. If problem still exists, replace the affected tool. (Refer to Section 8.3.4)
D1 - Tool/Servo Mismatch (Abnormal will clear when the tool and Axis Unit are properly
matched):
1. Verify the correct tool is being used for the application. (Refer to Section 2.5)
2. Determine which Axis Unit type is required to operate the tool. (Refer to Section 2.4)
3. Replace components as required.
D7 - overload (Abnormal will clear after depressing the RESet switch):
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 affects only 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 8.3.3)
7. If problem still exists, replace the affected tool. (Refer to Section 8.3.4)
