Parameter Interpretation
The parameters listed in the following partly represent the characteristics of the C505 and partly its
demands on the system. To aid in interpreting the parameters right, when evaluating them for a
design, they are marked in column “Symbol”:
CC (Controller Characteristics):
The logic of the C505 will provide signals with the respective characteristics.
SR (System Requirement):
The external system must provide signals with the respective characteristics to the C505.
