Okuma Alarm-A 1470 APA range XS-axis
Actual position reachea the soft-limit during synchronization operation (in other than learning).
During learning operation, actual position data exceeds the value which is the sum of the maximum position command value and the parameter setting (XS AXIS SYATEM PARAMETER NO.6) or becomes smaller than the value which is the difference between the minimum position command value and the parameter setting (XS AXIS SYATEM PARAMETER NO.6).
1->The actual position data exceeds the allowable range in the positive direction.
2->The actual position data is smaller than the smallest limit of the allowable range in the negative direction.
Probable Faulty Locations
The command given in the synchronization mode is too large.
The compensation data exceeds the proper amount during lerning operation.
Faulty position encoder.
Measures to Take
Review the cutting conditions.
Review the setting of the learning operation monitoring parameter (XS AXIS LEARNING CONTROL PARAMETER No.6).
Check the position encoder.
