2.2 Functional Blocks

Figure 2-2 shows the functional block diagram of the IDDK. Dedicated processors provide the system with control, real-time connectivity, and safety functions. The control processor has a suite of position encoder interfaces and current sense interfaces. You can configure the controller to select the interfaces you want. Table 2-1 shows that each block is subdivided into macros representing a subfunction.
