Single-Axis Series AC1120Si
Inertial System Rate Table – Rotary Stage

AC1120Si V1.0, V2.0 and V3.0

Major Features
The drive assembly is mounted on a cast iron angle bracket
for use in horizontal or vertical orientation.
It is equipped with a direct drive brushless motor providing
high torque and smooth rates over a wide operating range.
Table support points are precision-machined perpendicular orparallel to the table axis. For small payloads the table can beused freestanding.
High dynamic applications and/or large payloads require thetable to be bolted to a rigid support surface.
A 30-way slip ring connects the Unit Under Test (UUT) to thetable base. The lines terminate in two D-SUB connectors on
the table top and corresponding connectors on the table base.
The rate table is operated from a host computer via RS-232
or optional USB interface. Other interfaces installed are
analog Inputs, digital Inputs/Outputs and CanBus.
Other optional interfaces are available on request.

• Designed to test inertial components, instruments and 		MEMS sensors• Used for development, production, in-process test,calibration and final inspection• Simulates environmental conditions when used in
combination with a thermal chamber• Horizontal axis for accelerometer testing or roll-oversensor testing• Precise positioning, smooth rate with zero drift and accurate
instantaneous rate stability• Easy customer software implementation• Short, ex-stock delivery of 3 standard configurations

The Graphical User Interface (GUI) allows the user to selectmodes, command motion set points, monitor systemvariables, and query status.
The GUI is used to customize the system configuration and toinitiate tuning and calibration procedures.
Analog signals may be entered, scaled, and summed with thedigital demands in position and rate mode of operation.
