PRODUCT OVERVIEW

Compact engineering.Production-ready control.

The FDA-113-ECO is a single-axis rate table intended for development, production, in-process testing, calibration, and final inspection of inertial components and instruments, including MEMS sensors.

The datasheet emphasizes user-friendliness and economic pricing. The system uses a highly reliable direct-drive servo architecture including a drive assembly, servo controller, and power amplifier.

Its drive assembly includes a direct-drive torque motor, optical encoder, precision-machined tabletop, and slip ring assembly. The absolute optical encoder is mounted directly to the axis for high-precision positioning.

All systems are supplied with the necessary interconnecting cables and mating connectors for the customer interface. The page uses the neutral catalog-supported term “direct-drive torque motor” because the source itself uses inconsistent brushed/brushless wording.
