KDA 2.1-100-3-LY0-W1

The KDA 2.1-100-3-LY0-W1, Bosch Rexroth Indramat, KDA Spindle Drives identifies a high-performance main spindle drive engineered for demanding machining and milling applications. Delivering a continuous Rated Current of 100 A and a robust DC Bus Voltage of 300 V, this unit harnesses precise digital control to achieve rapid acceleration and stable torque under load. Its compact packaging and integrated drive electronics streamline installation in multi-axis machine tools. A sealed, rugged housing protects sensitive components against contaminants in harsh industrial environments.

Designed for rigorous duty cycles, the KDA 2.1-100-3-LY0-W1 incorporates a forced cooling system via a Heatsink Blower with a dedicated Heatsink Blower AC Supply Voltage of 220 VAC to maintain optimal thermal performance. The drive supports a bidirectional Encoder Input Type with both Auxiliary & Synchronous channels, enabling accurate feedback for closed-loop positioning. Communication relies on a high-speed Speed Command Interface through SERCOS, ensuring deterministic motion control and low-latency synchronization with CNC controllers. The internal power stage conforms to the Product Model specification KDA Series 2, while the drive’s design classification Design 1 meets global machine safety standards. With an Auxiliary Interface of None, the system minimizes peripheral dependencies and reduces wiring complexity.

Integration into existing Bosch Rexroth systems is seamless, leveraging standardized mounting and parameterization through the familiar Rexroth toolchain. Proven reliability under continuous operation makes the drive ideal for high-stiffness spindles where precision, repeatability, and uptime are critical. Users benefit from reduced commissioning time and simplified maintenance, as the KDA 2.1-100-3-LY0-W1 offers plug-and-play connectivity and a durable, service-friendly layout conducive to rapid troubleshooting and long-term productivity gains.
