KDA 3.1-150-3-DPS-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-DPS-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat integrates a Rated Current of 150 A with a DC Bus Voltage of 300 V to deliver precise spindle control. Featuring a Digital 16-Bit Parallel Speed Command Value and Forced Cooled by Heatsink Blower configuration, this drive ensures stable thermal performance under heavy loads. Its AC Supply Source for Heatsink Blower: 220 VAC and robust Cooling: Forced Cooled by Heatsink Blower system maintain optimal operating temperatures even during continuous duty cycles. With support for Aux. Encoder Input for spindle or second motor feedback and a flexible Aux. Interface: Serial Interface RS 232 C, the KDA 3.1-150-3-DPS-W1 is designed to integrate seamlessly into diverse CNC and machine tool environments.

This spindle drive’s core architecture (Design: 1) and modular Product: KDA platform enable high stiffness and precise positioning throughout an extensive speed range. The built-in digital speed command interface enhances response times, while the Series: 3 design family ensures uniform mechanical dimensions and installation procedures across similar drives. Forced cooling via heatsink blower supports sustained output without derating, and the encoder input path allows direct real-time feedback for advanced position and speed regulation. Serial communications over RS 232 C simplify parameter configuration, monitoring, and diagnostics during commissioning and maintenance.

Optimized for main spindle applications in milling, turning, and grinding centers, the KDA 3.1-150-3-DPS-W1 drive provides continuous power delivery, tight speed stability, and reliable performance under cyclical loads. Its combination of high current capacity, digital command precision, and efficient cooling makes it an ideal choice for demanding machine tools requiring superior torque control and thermal endurance.
