Operational Overview

Figure 22:

Indexes View

Indexes use acceleration and deceleration ramps which may or may not reach the specified velocity depending on the total distance and the ramp values. For example, a short move with long acceleration and deceleration ramps may not reach the target velocity entered.

Indexes cannot be initiated when any other motion (jogging, homing, or program) is in progress. Indexes can be aborted with the Stop destination found in the Ramps group on the Assignments View.

The FM-3 module supports five types of indexes: absolute, incremental, registration, rotary plus and rotary minus.
