TDA 1.3-100-3-DP0

The TDA 1.3-100-3-DP0, Bosch Rexroth Indramat, TDA Main Spindle Controllers delivers precision control for high-performance spindle applications. This main spindle controller features a Rated Current of 100 A with a Continuous Effective Current of 70 A and a DC Link Circuit Rated Voltage of 300 V. The unit weighs 10.5 kg, making it easy to install in compact machine tool cabinets. Native support for a digital command value ensures crisp, noise-resistant speed regulation over long cable runs.

Built for exacting motion control, the controller detects rotor position with a Motor Feedback Resolution of 1/2 000 000 revolutions and includes an Additional Encoder Input for dual-feedback schemes. The Speed Command Interface is a 16-bit parallel digital bus, seamlessly integrating with PLCs. It operates across an Ambient Temperature Range of +5 °C to +45 °C (max 55 °C) and up to 1000 m elevation. Rated Humidity Class F per DIN 40040 and Protection Rating IP10 per DIN 40050, it withstands solid contaminant ingress down to 50 mm class.

Designed for reliability and simple integration, the TDA 1.3-100-3-DP0 plugs directly into existing DC link and feedback infrastructure without additional interfaces. Its robust IP10 enclosure and Humidity Class F qualification ensure consistent uptime in dry, hot, or cold shop environments. Ideal for CNC main spindles, drilling heads, and rotary tables, it combines precision, ruggedness, and straightforward PLC connectivity for accelerated machine commissioning.
