TDA 1.1-050-3-LP0

TDA 1.1-050-3-LP0, Bosch Rexroth Indramat, TDA Main Spindle Controllers opens a new chapter in high-performance spindle control with a robust, digitally native platform. This controller delivers precision regulation to both INDRAMAT asynchronous spindle motors and 2AD frameless main spindle motors, supporting up to 10 kW of continuous power output. Engineered in a modular form factor, the device integrates power, motor/NC, and auxiliary electrical connections into a streamlined housing. Weighing 10.5 kg and measuring 360 mm in length, the unit offers a compact footprint without sacrificing performance.

Bosch Rexroth Indramat’s TDA 1.1-050-3-LP0 features a Rated Current of 50 A alongside a Continuous Effective Current of 35 A to drive demanding machining spindles. A SERCOS interface Command Value ensures deterministic, real-time communication between controller and motor, while a Link Rated Voltage of 300 V underpins stable operation. The controller tolerates ambient conditions up to +55 °C and elevations up to 1000 m, protected within a rugged enclosure. Mounting considerations call for a minimum panel thickness of 3 mm steel or 6 mm aluminum to maintain thermal dissipation and mechanical stability.

Integration into automated systems is seamless: the SERCOS interface communication module synchronises spindle speed and torque feedback within multi-axis networks, eliminating jitter and phase drift. The modular design reduces mean time to repair, and global shipment is backed by a 1 year warranty for dependable uptime. In demanding industrial settings—from high-speed milling to precision grinding—the TDA 1.1-050-3-LP0 delivers consistent, reliable main spindle control to optimise throughput and quality.
