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 Motor category, click Commutation Diagnostics.

2.

Set the parameter Test Current to 25%.

3.

Click Start Test.

The slider will move approximately 60 mm (2.4 in.).

4.

Verify that the Test Status displays Test Success.

5.

Verify that the Recommended Changes displays No Change Required.

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.

From the Workspace, select Tuning.

2.

Click Autotuning.

3.

Set the parameters to the following values.

4.

Click Start Autotune.

The Velocity Regulator Gains changes to reflect autotune values.

The Autotune Complete status indicator turns yellow.
