TDA 1.3-100-3-API

TDA 1.3-100-3-API, Bosch Rexroth Indramat, TDA Main Spindle Controllers opens the door to precision digital control of asynchronous 2AD and frameless 1MB spindle motors. This Main Spindle Controller delivers intelligent drive management with an analog command value interface and is optimized for constant power ratings between 3 and 10 kW at the motor shaft. Weighing just 10.5 kg, it mounts easily within modern machine tool cabinets without compromising service access. The controller’s firmware enables high-accuracy position loops and seamless integration as a servo axis for demanding CNC applications.

In its compact package, the TDA 1.3-100-3-API consolidates robust electrical performance: it sustains a Rated Current of 100 A and a Continuous Effective Current of 70 A under nominal conditions. Auxiliary supply demands are modest—power consumption is 1.4 A at +24 V load voltage and 160 mA at ±15 V test voltage—while the DC link supports a Rated Voltage of 300 V. The permissible ambient temperature range spans +5 … +45 °C at sea level, and the unit can be installed up to 1000 m altitude without derating. Protective measures include overvoltage monitoring, integrated temperature sensors, and a rugged housing optimized for airflow inside the control cabinet.

Engineers benefit from parameter-driven tuning that matches spindle characteristics to specific machine dynamics, reducing commissioning time and variability. The TDA 1.3-100-3-API’s high-stiffness control loop ensures stable torque and speed across a wide range, enhancing surface finish consistency. Backed by Bosch Rexroth Indramat’s proven reliability and a one-year global warranty, this controller excels in high-precision machining, grinding, and milling applications where uptime and accuracy are critical.
