TDA 1.3-100-3-APD

The Bosch Rexroth Indramat TDA 1.3-100-3-APD from the TDA Main Spindle Controllers series delivers high-performance spindle control in a compact, industrial-grade package. This main spindle controller features a rated current of 100 A and a continuous effective current of 70 A, driven by an analog command value interface for smooth, precise regulation. Weighing just 10.5 kg, the unit supports 2AD asynchronous motors and 1MB frameless motors with a continuous power range of 3 kW to 10 kW, making it suitable for a variety of machining spindles. Engineered for advanced motion applications, it combines robust construction with dynamic responsiveness for demanding industrial use.

Beyond its core power ratings, the TDA 1.3-100-3-APD incorporates a smart internal position control loop that delivers a spindle positioning accuracy of 1/4 000 000 revolutions. Rotor position can be detected and controlled at extremely low speeds with an accuracy of 1/2 000 000 revolutions, supporting high-precision C-axis operations such as thread cutting. The controller provides an incremental encoder output interface for direct position feedback and a serial interface for loading and saving drive parameter sets via computer. A one-year warranty ensures dependable support and worldwide service availability.

Designed for seamless integration into multi-axis systems, this spindle controller can operate in conjunction with feed-axis drives or as a standalone main spindle unit. Its high-stiffness response and fine current loop tuning minimize overshoot and vibration, optimizing surface finish and tool life. Combining compact form factor, advanced positioning features, and versatile interfaces, the TDA 1.3-100-3-APD is a precision solution for modern CNC and automation systems.
