TDA 1.3-100-3-D00

The TDA 1.3-100-3-D00, Bosch Rexroth Indramat, TDA Main Spindle Controllers is engineered for intelligent digital control of asynchronous main spindle motors. It supports motor power ratings from 3 kW to 10 kW and communicates via a digital command value interface. Weighing 10.5 kg and occupying a streamlined footprint, the controller simplifies installation in compact drive cabinets. Its robust housing with standardized mounting handles ensures safe handling during setup.

The device accepts a link circuit rated voltage of 300 V and delivers a rated current of 100 A with a continuous effective current of 70 A. Auxiliary power consumption at a +24 V load voltage is 1.4 A, while the ±15 V test voltage rail draws 160 mA. The controller operates reliably across a nominal ambient temperature span of +5 to +45 °C, with reduced rating up to +55 °C, and can be stored or transported between -30 to +85 °C. A sealed enclosure and optimized thermal management maintain performance under factory conditions.

Integration into existing Bosch Rexroth Indramat systems is seamless through its digital interface and standardized connectors. Built-in diagnostics and robust current handling enhance reliability, minimizing downtime in high-speed spindle applications. This controller is ideal for CNC machining centers, drilling rigs, and precision milling spindles requiring precise torque and speed control.
