The function of each Sink parameter has been pre-defined and cannot be
changed. For example, Parameter 151 (Logic Cmd 2) has been specifically
set aside for the function of drive logic control. Because each Sink
parameter has been defined for a specific use, each Sink parameter will
have a specific data type and units of measure.
For example, Parameter 151 (Logic Cmd 2) is a 16 bit word where each bit
has been defined for a specific function such as Start, Stop, Close
Contactor, etc. A description of each parameter is provided in Chapter 7.
The specific external control devices which can be interfaced with the
drive are defined by the type of Adapter Boards connected to Microbus
Ports A and B on the Main Control Board. For example, the drive could be
controlled by discrete hardware such as push buttons and pots. In this case,
a Discrete Adapter Board would be required to interface the discrete
control hardware to Port A. If interface with a PLC is desired, a Node
Adapter Board is required in Port B.
Each Adapter Board also has Sink parameters associated with it as shown
in Figure 5.2.
