KDA 3.1-100-3-DPS-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-DPS-W1 from the KDA Spindle Drives series offers a robust solution for high-precision machine tool applications. Designed and manufactured by Bosch Rexroth Indramat, this main spindle drive delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V to ensure continuous power under varying load conditions. Featuring a Digital 16-Bit Parallel Speed Command Value, the drive achieves superior positioning accuracy and extremely low speed ripple across its extensive speed range. With a compact Design 1 housing and forced cooling via an integrated heatsink blower, this unit balances performance and serviceability in modern CNC systems.

Engineered for industrial environments, the KDA 3.1-100-3-DPS-W1 incorporates an AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal thermal conditions. The Aux. Encoder Input with support for spindle or second motor feedback allows dual-loop control for synchronized axis performance. Communication is handled through the Aux. Interface Serial Interface RS 232 C, streamlining parameterization and diagnostic access. Forced cooling by heatsink blower and the rugged Product: KDA construction enable reliable operation at elevated ambient temperatures without derating. The drive’s Series 3 configuration ensures consistency with other KDA models, simplifying spare parts management.

This spindle drive is ideally suited for high-stiffness, high-dynamics machining centers, where precision and repeatability are critical. Its comprehensive feature set—including digital speed command, dual encoder feedback capability, and serial communication—reduces commissioning time and enhances overall system diagnostics. The KDA 3.1-100-3-DPS-W1 stands out as a high-performance spindle drive platform that meets the rigorous demands of modern manufacturing.
