Modulo axis
A modulo axis is an axis with an in󹪝nite traversing range, e.g.:
• Rotary table
• Conveyor belt
• Roller conveyor

The converter maps the modulo range on the position actual
value. If the load position leaves the modulo range, then the
value range of the position actual value repeats in the convert‐
er.
Setting the modulo range
Requirements
• You are online with Startdrive.
• You have selected the "Mechanical system" screen.
Procedure


1. Enable the modulo correction.
2. De󹪝ne the modulo range.
Example 1: In the case of a rotary table, one load revolution corresponds to 3600 LU. In this
case, the modulo correction is also 3600.
Example 2: For a roller conveyor, 100 motor revolutions corresponds to one production cycle.
For a resolution of 3600 LU per motor revolution, the modulo range is 360000 LU.
