Hookup Test
Run the hookup test before the linear thruster loads or fixtures are installed. Vertical loads or
external forces of more than 10% of the rated load may prevent the hookup test from passing,
even though the unit is wired correctly.
Follow these steps to do the hookup test for the linear thruster.
1. From the Hookup Axis Properties tab enter the following
2. Click Test Command & Feedback.
Tune
The linear thruster is a direct drive actuator. Tuning the linear thruster establishes a stable axis.
Follow these steps to tune the linear thruster.
1. Attach your application load to the linear thruster.
2. From the Tune tab enter the following recommended tuning parameters.
3. Click Start Tuning.
You can fine tune the linear thruster for your specific application requirements by using
the suggestions made in the next section.
