KDA 3.1-100-3-AQS-W1

KDA 3.1-100-3-AQS-W1, Bosch Rexroth Indramat, KDA Spindle Drives deliver a robust spindle drive solution designed for demanding machining and precision tooling applications. This main spindle drive features high stiffness and precision positioning capabilities, ensuring consistent performance across a wide speed range. The compact drive integrates seamlessly with existing CNC controller architectures, providing immediate responsiveness to speed and torque commands. Built on decades of Rexroth Indramat innovation, it combines proven reliability with advanced motion control functions.

Incorporating a Rated Current of 100 A and a DC Bus Voltage of 300 V, the KDA 3.1-100-3-AQS-W1 handles peak power demands with ease. The drive's Cooling system employs forced cooling by heatsink blower powered by a dedicated AC Supply Source for Heatsink Blower at 220 VAC to maintain optimal operating temperatures. Precision feedback is supported via an Aux. Encoder Input for 1 V Sinusoidal signals, while a robust Aux. Interface using Serial Interface RS 232 C simplifies parameterization and diagnostics. Engineers can command speed through an Analog +/– 10V Speed Command Value, enabling smooth acceleration and deceleration profiles. The KDA series architecture is identified by Design 1 and Product KDA elements in Series 3, ensuring consistent hardware and firmware compatibility across module upgrades.

Designed for seamless integration into machining centers and robotic spindles, this drive's modular interface and standardized control protocol reduce commissioning time. The forced-cooling heatsink blower enhances long-term reliability under continuous operation, while the analog speed command interface supports legacy and modern controllers alike. Ideal for high-precision drilling, milling, and turning applications, the KDA 3.1-100-3-AQS-W1 elevates throughput with minimal downtime and exceptional dynamic response.
