The LDAT linear thrusters display different suffixes depending on the
servo drive used. Systems with a 230V drive show linear thrusters with a
_A suffix and system with a 460V drive shows _B suffix.
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 can 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. When you tune a linear thruster, it
establishes a stable axis.
Follow these steps to tune the linear thruster.
