TDA 1.3-050-3-A0S

The TDA 1.3-050-3-A0S, Bosch Rexroth Indramat, TDA Main Spindle Controllers combine to deliver precise spindle regulation for demanding machining centers. The controller supports a Command Value of analog format, ensuring compatibility with a broad range of analog command signals. With a Rated Current of 50 A and a Continuous Effective Current of 35 A, it maintains high torque stability across varying loads. Its compact form factor weighs only 10.5 kg, simplifying retrofit into existing machine architectures.

Specifications emphasize durability and adaptability: the unit features a Protection Degree of IP10 and a Humidity Class of F, allowing operation in moderate industrial environments. An integrated RS 232C serial interface provides reliable bidirectional communication for parameter editing and diagnostics. The controller’s Link Circuit Rated Voltage of 300 V supports direct DC link integration, while its Max Installation Height rating of 1000 m above sea level preserves nominal performance up to specified altitude. Ambient conditions from 5 °C to 45 °C are accommodated without derating, and the built-in programmable module enables rapid transfer of configurations to replacement units.

Engineers appreciate the TDA 1.3-050-3-A0S’s seamless integration with 2AD/1MB spindle motors and compatibility with other Rexroth axes controllers for multi-axis systems. Its robust analog command scheme and industrial-grade protection classes ensure reliable long-term operation in milling, drilling, and grinding applications. When paired with Rexroth’s automation suite, the controller enhances process stability, reduces commissioning time, and maximizes spindle uptime.
