KDA 3.1-100-3-LPD-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-LPD-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a rated current of 100 A and a DC Bus Voltage of 300 V. Designed for robust industrial operation, the drive features an AC Supply Source for Heatsink Blower of 115 VAC and is forced cooled by heatsink blower to maintain optimal thermal stability under continuous load. Integration is simplified through a SERCOS - Interface Speed Command Value input, ensuring high-resolution speed regulation across its extensive range. A 16-bit parallel position command value digital auxiliary interface further enhances synchronization capabilities in multi-axis arrangements.

Precision positioning is supported by an auxiliary encoder input accommodating spindle or secondary motor feedback, enabling closed-loop control with sub-micron accuracy. The unit’s Design 1 architecture combines high stiffness and rigidity, minimizing torsional deflection during rapid acceleration and deceleration. With a compact profile and consistent mounting footprint, the KDA 3 series product slots effortlessly into existing machine tool frameworks. The drive’s dedicated digital interfaces provide deterministic communication and low-latency command execution for high-speed machining processes.

Engineered for demanding CNC applications, this spindle drive balances continuous power delivery with dynamic responsiveness, making it ideal for drilling, milling, and grinding operations. Its robust construction and advanced cooling system ensure reliable performance even under extended duty cycles. The KDA 3.1-100-3-LPD-U1 represents a high-performance solution for manufacturers seeking precision, versatility, and longevity in spindle drive technology.
