KDA 3.2-150-3-DYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives represents a high-performance main spindle drive engineered for precision machining and demanding automation tasks. This unit delivers a continuous Rated Current of 150 A into a robust DC Bus Voltage of 300 V, ensuring stable torque delivery across a broad speed range. Its high stiffness design optimizes dynamic response, while integrated positioning features support demanding contouring and indexing operations. With a digital interface and forced-cooling system, the drive maintains consistent performance under sustained load.



For thermal management, the drive employs a Cooling scheme of Forced Cooled by Heatsink Blower powered from an AC Supply Source for Heatsink Blower of 115 VAC, guaranteeing reliable heat dissipation. Position feedback and synchronization leverage the Aux. Encoder Input with auxiliary and synchronous signals compliant with AS 35 standards. Command integration is handled via the Aux. Interface using a Position Command Value Digital 16-Bit Parallel bus, while speed regulation is driven by a Speed Command Value Digital 16-Bit Parallel input. The device’s compact Design (Type 2) and modular form factor in the Series 3 framework simplify retrofit into existing machine tool architectures.



System integrators benefit from the drive’s seamless compatibility with Rexroth automation platforms and its proven reliability in continuous-duty applications. The forced-cooling blower and hardened electronics deliver high uptime even in harsh production environments. As part of the KDA Spindle Drives family, the KDA 3.2-150-3-DYD-U1 offers precise speed control, rapid acceleration, and durable construction ideal for CNC spindles, grinding machines, and high-speed milling centers.
