TDA 1.3-050-3-L00

The TDA 1.3-050-3-L00, Bosch Rexroth Indramat, TDA Main Spindle Controllers deliver precise spindle management through a robust, front-mounted protective cover that remains securely screwed in during operation. The controller supports a Rated Current of 50 A and maintains a Continuous Effective Current of 35 A to ensure stable torque delivery across the full speed range. It employs an integrated Command Value via a SERCOS interface for high-speed communication and closed-loop control. With a total Weight of 10.5 kg, the unit balances solid mechanical design and compact footprint to fit into standard CNC machine tool cabinets.

The controller integrates a dedicated X3 connector for direct motor feedback, enabling the internal position control loop to close on signals from the main or optional spindle in real time. An optional Position Signal Output is compatible with incremental encoders, allowing secondary axes or measurement systems to share a common timing reference. Designed to withstand harsh production environments, it offers a Storage Temperature Range of -30 °C … 85 °C and tolerates up to 70% RH without performance degradation. Core power cables are factory-specified to be twisted, while sub-miniature D-type connectors screw firmly into place, eliminating loose connections under vibration.

Engineered for seamless integration, the TDA 1.3-050-3-L00 slips into machine tool centers with minimal cabinet modifications and communicates directly with existing SERCOS networks. Its rigid protective housing and controlled fastening torque guidelines prevent mechanical failures during high-speed operation, promoting long-term reliability. Precision rotor position detection at low speeds enhances surface finish quality and repeatability, making the controller ideal for demanding milling, turning, and multi-axis machining applications.
