Follow these steps to home the linear thruster.
1. From the Workspace, select Mode Configuration>Homing.
2. Set the parameters to the following values.
If linear thruster does not move to negative spring stop during homing,
it can be necessary to increase the Home Current Value.
3. From the Workspace, select Indexing.
4. Set the parameter Auto Start Index to Off.
5. Click Indexing Control Panel.
6. Click Enable Drive.
7. Click Start Homing.
The linear thruster moves to the negative spring stop and returns to the
home position.
The In Position and At Home status indicators turn yellow.
Setting Travel Limits Linear thrusters are designed to use the software overtravel limits available in
Logix Designer application and Ultraware software.
Overtravel limits must be set according to the maximum speed of the servo
drive system and the payload of the application. The Deceleration Distance
before the slide contacts the end-of-travel bumpers can be determined based on
the Deceleration Rate of the load, and the available peak force from the stage-
drive combination. Then use Motion Analyzer software to calculate the
minimum deceleration distance at the maximum speed of your application.

(1) Velocity and kinetic energy can be much higher due to uncontrolled, worst-case motion that is constrained only by the length of
stroke and the power capacity of the motor-drive pairing.
