Discrete Inputs in the Drive are used for Inputs 1 and Input 2. Output A, B, C,
and D are linked to DeviceLogix Scratchpad Registers. This allows further
flexibility to modify the values of these outputs.
The resulting output can be linked to a parameter and used in supporting drive
applications, such as configuring multiple preset speeds and point to point
positioning. In this example, it controls Preset Speed 1.
