1291BL Single Axis Rate Table

The Model 1291BL Single Axis Rate Tables are designed to provide precise position, rate, and acceleration motion for development or production testing of commercial or military inertial sensors. The 1291BL was specifically designed for testing today’s considerably smaller inertial sensors and systems.

Accurate and reliable motion control of the 1291BL Test Table is achieved with a servo-controlled system consisting of a direct-drive brushless torque motor, a precision absolute optical encoder, and an internal microprocessor-based motion control card.

Position, rate, and acceleration, as well as motion profiles, are commanded remotely from a host PC (not provided) via the standard RS-232 communication interface. The user can utilize an Ideal-provided LabVIEW™, application program or their own communication software package with Ideal’s software command set to precisely control the 1291BL. The 1291BL utilizes the latest controller technology, configured in a 19-inch rack-mountable servo controller that interfaces to the host PC.
