TDA 1.3-100-3-D0D

The Bosch Rexroth Indramat TDA 1.3-100-3-D0D from the TDA Main Spindle Controllers series delivers precision spindle control with a rated current of 100 A and a continuous effective current of 70 A. This main spindle controller utilizes a digital command value interface to achieve rapid response and repeatable positioning. At a weight of 10.5 kg, the drive balances compact installation with robust construction. Seamless integration into machining centers is facilitated by its proven reliability and industry-standard mounting envelope.

Engineered for demanding environments, the TDA 1.3-100-3-D0D features a link circuit rated voltage of 300 V within the control cabinet and supports installation at up to 1000 m altitude without performance degradation. Its auxiliary power requirements include 1.4 A at +24 V load voltage and 160 mA at ±15 V test voltage, ensuring stable electronics operation. Ambient tolerances span +5 to +45 °C at nominal ratings, with a maximum permissible ambient of +55 °C under reduced load to maintain optimal thermal performance.

To safeguard longevity during logistics, the controller tolerates storage and transport temperatures from –30 to +85 °C. Designed for high-speed machining, this spindle controller offers automatic position control with micro-revolution resolution and proven compatibility with existing Indramat ecosystems. Durable, precise, and backed by Bosch Rexroth Indramat’s field support network, the TDA 1.3-100-3-D0D ensures uptime in even the most rigorous applications.
