KDA 3.1-100-3-LYI-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-LYI-W1 from the KDA Spindle Drives series delivers robust spindle control with a Rated Current of 100 A and a DC Bus Voltage of 300 V. Engineered for precision and rigidity, this drive employs a Speed Command Interface: SERCOS to achieve dynamic positioning and extensive speed range in continuous power applications. The drive features dual encoder support through an Auxiliary Encoder Input: Synchronous & Auxiliary port, paired with an Auxiliary Interface: Incremental Encoder Output for seamless feedback integration. With a Product Series: KDA base and Series Number: 3, its Design: 1 construction ensures consistent mechanical and electrical compatibility across Rexroth spindle platforms.

Precision thermal management is assured by a Cooling Method: Forced air via heatsink blower, drawing power from a dedicated Heatsink Blower AC Supply: 220 VAC circuit. This forced cooling system maintains optimal operating temperature even under prolonged high-current operation, reducing thermal drift and preserving spindle accuracy. The compact heatsink blower assembly integrates directly into the drive housing, minimizing cabinet footprint while delivering efficient heat dissipation. Continuous monitoring of current and voltage parameters safeguards against overload, supported by built-in diagnostics for rapid fault identification.

Ideal for CNC machining centers, grinding spindles, and high-speed milling operations, the KDA 3.1-100-3-LYI-W1 balances torque density with reliability. Its precise encoder interfaces and SERCOS network compatibility simplify commissioning and ensure repeatable motion control performance. Backed by Bosch Rexroth Indramat’s engineering pedigree, this spindle drive offers the performance and ruggedness required for demanding industrial environments.
