KDA 2.1-100-3-LQD-U1

KDA 2.1-100-3-LQD-U1, Bosch Rexroth Indramat, KDA Spindle Drives set a new standard in main spindle control with a robust enclosure and high-stiffness design. This drive delivers a continuous Rated Current of 100 A into a DC Bus Voltage of 300 V, ensuring powerful torque delivery across the full speed range. High-precision positioning features and an extensive speed band facilitate rapid acceleration and deceleration for complex machining cycles. Native support for digital and parallel interfaces streamlines integration into modern CNC and motion-control systems.

Built around the proven Design 1 framework of the Product KDA family, this unit employs a Position Command Value Digital 16-Bit Parallel Aux. Interface and an advanced SERCOS - Interface Speed Command Value input to achieve sub-microsecond response times. The drive’s Aux. Encoder Input accepts a 1 V sinusoidal signal for closed-loop feedback, while an onboard heatsink blower provides Forced Cooled by Heatsink Blower thermal management powered by a dedicated AC Supply Source for Heatsink Blower at 115 VAC. All control electronics are conformally coated to withstand harsh shop-floor environments, and dual internal fans ensure consistent thermal performance under peak loads.

Engineers benefit from the drive’s plug-and-play compatibility with Bosch Rexroth Indramat controllers, reducing commissioning time and cabling complexity. Robust forced-cooling and high overload capacity guarantee reliable operation in continuous-duty applications, while modular construction simplifies maintenance and upgrades. Ideal for high-speed milling, drilling, and grinding spindles, the KDA 2.1-100-3-LQD-U1 excels in precision manufacturing environments demanding accuracy, repeatability, and uptime.
