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

Figure 16 shows an overview for the CncAxisType. It is formally defined in Table 14.
