TDA 1.1-100-3-D00

The Bosch Rexroth Indramat TDA 1.1-100-3-D00 from the TDA Main Spindle Controllers series delivers precise spindle management with a rated current of 100 A and a continuous effective current of 70 A. It accepts a digital command value interface and features a 16-bit parallel digital command value channel for high-resolution speed control. Weighing just 10.5 kg, the TDA 1.1-100-3-D00 combines compact design with robust performance for intelligent control of 1MB and 2AD spindle motors. Its rugged construction and optimized airborne cooling method ensure reliable operation in modern NC machine environments.

The controller is powered by a 24 V load voltage source with a rated current of 1.4 A and includes a dedicated 15 V test voltage output rated at 160 mA for sensor and auxiliary device verification. Heat is efficiently removed by the air generated within its control cabinet, eliminating the need for external fans and reducing maintenance points. Integration is streamlined through the standard digital speed command interface, enabling seamless connection to PLCs even over long cable runs with minimal signal degradation. The absence of additional encoder inputs or interfaces simplifies wiring diagrams and reduces potential failure modes in complex machine tool setups.

Built for demanding industrial environments, the unit carries a protection type IP10 rating and is classified under humidity class F for resilient operation in humid conditions. It can operate at up to 1 000 meters above sea level without derating and tolerates ambient storage and transport temperatures from –30 °C to +85 °C. As a safety precaution, servicing and installation must be performed only by qualified technicians, ensuring long-term reliability and avoiding moisture condensation by maintaining a tightly sealed cabinet enclosure.
