Figure 61: Tuning View

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 the FM-3 Reference Manual.

PLS View

Use this view to setup Programmable Limit Switches (PLS), if your application requires

them. They are assigned in the same way as the Assignments views in Step 3 of this guide.

Step 3: Making Assignments

The Assignments view is found by expanding the I/O Setup group in the hierarchy. 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 your mouse pointer over the source you wish to assign to a

destination, click and hold the left mouse button. While still holding the button, drag your

pointer over the destination where you wish to assign this source, and release the button. The

“Assigned To” and the “Set From” columns should then reflect the assignment that has been

made. Figure 7 shows how these assignments are made.
