TDA 1.1-100-3-L0S

TDA 1.1-100-3-L0S, Bosch Rexroth Indramat, TDA Main Spindle Controllers opens a new chapter in high-precision spindle control with its robust SERCOS interface command link and a Rated Current of 100 A. Engineered by Bosch Rexroth Indramat for seamless integration into advanced CNC systems, this controller weighs only 10.5 kg while delivering industrial-grade performance. It bridges the gap between asynchronous and frameless motors—such as 2AD and 1MB types—transforming standard drives into high-accuracy servo axes with consistent torque over wide speed ranges. Native compatibility with the TDA Series ecosystem ensures plug-and-play commissioning and uniform control logic across multi-axis installations.

In continuous operation, the unit sustains a Continuous Effective Current of 70 A at a 24 V load voltage, drawing a modest 1.4 A power consumption for its logic circuits. The controller supports spindle power outputs from 3 kW to 10 kW, delivering dynamic responses with a control resolution of 1/4 000 000 of a revolution. An incremental encoder interface elevates position tracking to 360 000 increments per revolution in C-axis mode, enabling nanometric positioning accuracy. High-speed closed-loop feedback continuously compares actual spindle parameters against programmed setpoints, ensuring a stiff, jitter-free response to load transients.

Beyond raw performance, the TDA 1.1-100-3-L0S excels in reliability and system integration. Its industrial design meets stringent long-term stability requirements, minimizing drift and maintenance intervals. As part of the TDA Main Spindle Controllers line, it effortlessly pairs with Rexroth HMI and PLC platforms for centralized supervision, fault diagnostics, and recipe management. Ideal for high-end CNC lathes, milling centers, and grinding machines, this controller guarantees precision, repeatability, and uptime in the most demanding manufacturing environments.
