The SpindleMonitoringType is a collection of information about the rotary process axis.

Depending on the actual context of the machine tool, this may for example be a tool-holding milling spindle or a workpiece-holding turning spindle.

The SpindleMonitoringType is formally defined in Table 20.

Subtype of the WorkingUnitMonitoringType defined in 8.3.3 i.e. inheriting the InstanceDeclarations of that Node.          
0:HasComponent Variable IsRotating 0:Boolean 0:BaseDataVariableType M, RO
0:HasComponent Variable Override 0:Double 0:AnalogUnitRangeType O, RO
0:HasComponent Variable IsUsedAsAxis 0:Boolean 0:BaseDataVariableType O, RO

IsRotating being True indicates if the spindle is rotating and has a valid commanded rotation speed.

Override is representing the current value of the spindle override.

IsUsedAsAxis being True indicates if the monitored element is used as an axis or, if False, as a spindle. If IsUsedAsAxis is True, the values of IsRotating and Override shall not be used by a client.
