TDA1.3-100-3-A0I

TDA1.3-100-3-A0I, Bosch Rexroth Indramat, TDA Main Spindle Controllers offers a precision-engineered solution for main spindle drive systems. It delivers a Rated Current of 100 A with an analog speed interface and maintains a Continuous Effective Current of 70 A to ensure smooth torque delivery. The unit’s robust design weighs just 10.5 kg, simplifying cabinet integration and reducing support structure requirements. Built on Rexroth’s decades of motion control expertise, this controller is tailored for high-performance CNC applications.

Featuring an onboard internal position control circuit with a resolution of 1/4 000 000 of a revolution, the controller achieves ultra-fine spindle positioning and reproducible motion profiles. It supports a power output range of 3–10 kW, matching asynchronous and frameless motors across a broad spectrum of machine tools. Command inputs accommodate analog speed command, digital speed command, and Sercos interface connectivity for flexible integration into existing automation networks. The parameter-based operation stores critical drive settings in the programming module at commissioning, ensuring rapid device replacement and consistent performance.

Engineers benefit from seamless integration into Rexroth’s drive ecosystems, with preconfigured parameter sets reducing setup time and commissioning effort. The TDA1.3-100-3-A0I’s high-resolution feedback loop and sturdy hardware design deliver reliable, repeatable spindle control under dynamic loads. Ideal for precision CNC machining, this controller enhances throughput, minimizes downtime, and upholds Bosch Rexroth’s hallmark of industrial reliability.
