KDA 3.1-150-3-DYD-U1

KDA 3.1-150-3-DYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives series excels as a robust main spindle drive, offering precision and reliability across diverse machining applications. It delivers a continuous Rated Current of 150 A and operates on a DC Bus Voltage of 300 V, ensuring sustained performance under heavy loads. The unit’s high stiffness design supports rapid acceleration and deceleration, while advanced positioning features enable micron-level accuracy. This spindle drive combines digital command flexibility with mechanical resilience to meet demanding production standards.

The drive incorporates a Forced (heatsink blower) Cooling Method paired with a dedicated Heatsink Blower AC Supply of 115 VAC, ensuring efficient thermal management during extended cycles. It features an Aux Encoder Input for auxiliary and synchronous feedback, alongside a Speed Command Input via 16-bit parallel digital signals for deterministic speed control. Position commands are handled through a 16-bit parallel position command Aux Interface, enabling seamless integration with CNC controllers. The compact Design 1 housing and modular Product Model KDA structure streamline installation into standard drive cabinets.

Engineers will appreciate the drive’s plug-and-play compatibility with Rexroth automation networks and its robust forced-cooling system for reliable operation in high-duty environments. Low-vibration construction and hardened components extend service intervals and minimize downtime. Ideal for high-speed spindles, milling, and turning centers, the KDA 3.1-150-3-DYD-U1 ensures consistent throughput and precision in modern machining applications.
