D7 - overload
(Abnormal will clear after depressing the RESet switch):
<CHECK ITEMS>
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)
