CNC Systems - 6.9 CncSpindleType

This OPC UA ObjectType represents a CNC spindle. CNC spindles can be subordinated to channels. They can change channel affiliation during runtime. For that reasons Objects of type CncSpindleType may be referenced by Objects of CncChannelType to inform about their current channel affiliation. At the same time all spindle Objects of a CNC system must be subordinated to the CncSpindleList regardless of their channel affiliation.

Figure 17 shows an overview for the CncSpindleType. It is formally defined in Table 15.
