Using DeviceLogix Appendix C

Figure 89 - Two Input Four Position Selector Switch Logic Map

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.

Parameter Configuration

The following parameters are configured for this example:
