KDA 2.1-150-3-AYD-U1

The KDA 2.1-150-3-AYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives presents a high-performance main spindle drive engineered for precision machining centers. This spindle drive delivers a stiff control loop with advanced positioning features and an extensive speed range, supporting continuous operation under demanding loads. Key specifications include a Rated Current: 150 A, a robust DC Bus Voltage: 300 V, and forced cooling via a heatsink blower to maintain thermal stability. Compact and modular by design, the unit integrates seamlessly into existing machine tool architectures while providing reliable torque delivery across varying speed demands.

Optimized for industrial spindle applications, the drive incorporates an Auxiliary Encoder Input: Auxiliary & Synchronous Inputs for high-resolution feedback and an Auxiliary Interface: 16-bit Digital Parallel Position Command that enables sub-micron positioning accuracy. The Cooling Method: Forced air (heatsink blower) ensures efficient heat dissipation, supported by a dedicated Heatsink Blower AC Supply: 115 VAC to power the fan unit. Control signals are managed through a precise Speed Command: ±10 V Analog interface, delivering smooth acceleration profiles and rapid response times. The unit’s Design: 1 chassis and Series Number: 2 identifier reflect a compact form factor optimized for rack-mounted installations, while the declared Product Series: KDA denotes compatibility with Rexroth’s suite of automation controllers.

Designed for seamless integration, the KDA 2.1-150-3-AYD-U1 thrives in multi-axis milling and turning centers, delivering consistent torque under transient loads. Its forced-air cooling and rugged construction promote uninterrupted operation in high-duty-cycle environments, minimizing maintenance intervals. Engineers benefit from reduced commissioning time and proven reliability, making this spindle drive an ideal choice for precision manufacturing applications demanding both performance and robustness.
