KDA 3.1-150-3-LY0-U1
KDA Spindle Drives
The Bosch Rexroth Indramat KDA 3.1-150-3-LY0-U1 from the KDA Spindle Drives series is a high-performance drive controller engineered for demanding industrial automation tasks. It accepts a balanced 3 x 380-460 V AC input at 50/60 Hz and delivers a continuous current rating of 150 A with a peak capability of 450 A for dynamic load requirements. Featuring an IP20 protection class and air cooling system, it ensures reliable thermal management without auxiliary infrastructure. With both digital/analog control interfaces and SERCOS-based speed command value, the unit integrates seamlessly into multi-axis control environments.
Detailed specifications include a DC bus voltage of 300 V, allowing stable power conversion and minimal ripple under load. An optional communication module provides expanded network connectivity, while integrated auxiliary encoder inputs support synchronous feedback with AS 35 protocols. The compact, panel-mount design eases installation in control cabinets, and the unit operates continuously within an ambient range of 0 °C to 45 °C. Built-in monitoring tracks internal temperature, current, and operating status, enabling predictive diagnostics and overcurrent protection.
By embedding advanced control and monitoring functions directly in the drive, the KDA 3.1-150-3-LY0-U1 minimizes reliance on external controllers and reduces system complexity. Its robust design and self-diagnostic capabilities enhance uptime and simplify maintenance planning. Ideal for high-precision turning, milling, and multi-axis robotic applications, this spindle drive delivers consistent performance and rapid fault response in industrial automation environments.
