TDA 1.1-050-3-API

The Bosch Rexroth Indramat TDA 1.1-050-3-API from the TDA Main Spindle Controllers series is engineered for precision digital control in demanding spindle applications. This main spindle controller delivers a rated current of 50 A with a continuous effective current of 35 A, ensuring consistent torque output and dynamic response. Utilizing an analog command value interface, it seamlessly integrates with existing NC controllers to regulate spindle speed and position. At a compact weight of 10.5 kg, the unit conserves cabinet space while maintaining robust construction for industrial environments.

Crafted for high reliability, the TDA 1.1-050-3-API features an internal position loop with an additional encoder input for precise feedback in C-axis or thread-cutting modes. It accepts a 300 VDC supply via the L- and L+ terminals and powers the motor through A1, A2, and A3 connections, simplifying wiring and reducing installation time. All operational parameters are entered on-site via the integral control-panel keypad and stored in a plug-in programming module for swift commissioning. The controller’s air-vent cooling system dissipates heat into the cabinet environment, maintaining stable operation within its specified temperature range.

Ideal for pairing with 1 MB frameless and 2AD asynchronous main spindle motors, the TDA 1.1-050-3-API offers high operational reliability and directional flexibility, with support for vertical mounting and a maximum installation altitude of 1000 meters. Drive diagnostics and fault codes are displayed directly on the control panel, expediting troubleshooting and minimizing downtime. Backed by a one-year replacement warranty, this controller represents a dependable solution for precision machining centers and automated manufacturing lines.
