Inertia Ratio - This parameter is the ratio between the reflected inertia of the load and the inertia of the motor rotor. For

assistance in calculating the Inertia ratio, see the Determining Tuning Parameter Values section of this manual.

PLS View

Use this view to setup Programmable Limit Switches (PLS), if the application requires them. They are assigned in the same

way as the Assignments views in Step 3 below.

Step 3: Making Assignments

The Assignments view is found by expanding the I/O Setup group in the Hierarchy Tree. The Assignments define how the

system operates. Sources, located on the left side of the view, are functions or events that activate based on drive/motor

activity. Destinations, located on the right side of the view, are functions that need to be triggered or activated (i.e. Index

Initiate, Program Initiate, etc.).

The example application requires initiating three indexes using three separate hardware inputs. Therefore, the Input Sources

need to be assigned to the Index Initiate Destinations.

To make an assignment, position the mouse pointer over the Source that will be assigned to a Destination, click and hold the

left mouse button. While still holding the button, drag the mouse pointer over to the Destination and release the button. The

“Assigned To” and the “Set From” columns should then reflect the assignments that have been made. Figure 103 shows the

Assignments view with these assignments made.
