KDA 3.1-100-3-LY0-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-LY0-U1 is part of the distinguished KDA Spindle Drives series and represents a high-performance solution for main spindle control in modern machining centers. Designed and manufactured by Bosch Rexroth Indramat, this spindle drive delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring robust power delivery. As a dedicated spindle drive, it excels at maintaining precise rotational speed and torque under varying load conditions, making it ideal for applications requiring high stiffness, accurate positioning, and an extensive speed range.

Incorporating forced cooling via a heatsink blower, the drive maintains optimal operating temperatures even under continuous load. The Heatsink Blower AC Supply of 115 VAC powers the integrated blower unit, ensuring efficient heat dissipation. The drive interfaces with motion controllers through a SERCOS speed command interface, providing deterministic real-time data exchange and synchronization. Auxiliary and synchronous inputs are supported through an Aux Encoder Input, enabling high-resolution feedback and seamless integration with external encoders. With a Series Number of 3 and Design code of 1, the KDA 3.1-100-3-LY0-U1 aligns to strict product family specifications to simplify selection and compatibility with existing KDA drive modules.

Built around the proven Product Family architecture of the KDA series, this spindle drive is engineered for reliability and long-term stability in industrial environments. The forced cooling method guarantees temperature stability, reducing thermal stress on power components and extending service life. Compliance with the SERCOS interface standard ensures compatibility with a broad range of CNC controllers and automation systems, streamlining commissioning and maintenance. The combination of high current capacity, standardized communication protocols, and robust cooling strategies culminates in a spindle drive that enhances machining precision, reduces cycle times, and optimizes throughput in demanding manufacturing operations.
