KDA 3.1-150-3-LQS-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-LQS-W1 from the KDA Spindle Drives series offers precision spindle control and robust performance in a compact design. Built under Design 1 standards and labeled as Product KDA within Series 3, this drive supports a Rated Current of 150 A and a DC Bus Voltage of 300 V for consistent torque and power delivery. It features an industry-standard Aux. Interface Serial Interface RS 232 C for configuration and diagnostics, and accommodates a Aux. Encoder Input for 1V Sinusoidal Signals to ensure high-resolution feedback. The drive’s modular build simplifies integration into milling, turning, and grinding machines.

The KDA 3.1-150-3-LQS-W1 excels under demanding thermal loads with its Cooling Forced Cooled by Heatsink Blower system, powered by a dedicated AC Supply Source for Heatsink Blower at 220 VAC. This forced-cooling arrangement maintains optimal operating temperatures even at full load, minimizing thermal drift and prolonging component life. The simplification of the enclosure and the use of rugged materials contribute to an elevated protection level suitable for industrial shop floors. Maintenance access is optimized through front-panel interfaces, reducing downtime during service cycles.

Position and speed control are governed via the Speed Command Value SERCOS–Interface, delivering deterministic real-time communication and seamless synchronization in multi-spindle configurations. High stiffness and a wide speed range enable rapid acceleration and deceleration, supporting complex machining cycles with continuous power output. With its professional-grade design, the Bosch Rexroth Indramat KDA 3.1-150-3-LQS-W1 drive represents a reliable solution for precision spindle applications where stability, repeatability, and endurance are paramount.
