The KDA 3.1-150-3-DQ0-W1, Bosch Rexroth Indramat, KDA Spindle Drives model delivers robust performance for main spindle applications. It features 150 A of rated current and a 300 V DC bus voltage to support high torque and wide speed ranges. The design emphasizes precise positioning with a Digital 16-Bit Parallel speed command interface. Forced cooling via an integrated heatsink blower ensures thermal stability under heavy loads.
Engineered with an AC Supply Source for Heatsink Blower of 220 VAC, the drive maintains constant thermal management via its Forced Cooled by Heatsink Blower system, drawing ambient air across the power stage heatsink. It accepts an Aux. Encoder Input for high-resolution feedback with a 1 V sinusoidal encoder, facilitating precise spindle speed control, while its auxiliary interface is provided Without additional digital I/O modules, simplifying system architecture. The compact Design 1 chassis houses power electronics optimized for continuous operation on a 300 V DC bus, delivering the nominal 150 A current at full load. This Series 3 product generation features modular installation, front-panel adjustments, and service-friendly access to replaceable components.
Seamless integration with CNC controllers and PLC networks allows the KDA 3.1-150-3-DQ0-W1 to deliver synchronized spindle motion and precise indexing. The drive’s proven reliability and high stiffness characteristics reduce mechanical resonance and enhance process stability. Ideal for milling, grinding, or drilling spindles, this unit streamlines machine tool productivity with minimal downtime.
