KDA 3.1-100-3-DP0-W1

KDA 3.1-100-3-DP0-W1, Bosch Rexroth Indramat, KDA Spindle Drives delivers a robust solution for high-precision spindle control. It provides a Rated Current of 100 A alongside a stable DC Bus Voltage of 300 V, ensuring consistent torque delivery across a wide speed range. Classified under Design category 1 and identified as Series 3, this 1-unit drive module combines high structural stiffness with precise positioning features. Its rigid frame and dynamic response characteristics are optimized for demanding CNC machining tasks where mechanical resonance and vibration must be minimized.

Equipped with an AC Supply Source for Heatsink Blower of 220 VAC, the drive’s Cooling scheme features a forced-cooled heatsink blower that maintains thermal stability during continuous operation. The advanced Speed Command Value input accepts a Digital 16-Bit Parallel signal, enabling sub-microsecond resolution for rapid speed adjustments. A dedicated Aux. Encoder Input supports feedback from the spindle or a second motor, delivering accurate position and speed monitoring. The absence of an Aux. Interface option reduces wiring complexity and enhances signal integrity, while the drive’s integrated power electronics ensure minimal electromagnetic interference.

Seamless integration into modern machine tool architectures is achieved via standardized power and feedback connections, accelerating commissioning and changeover. The forced cooling and robust electrical specifications guarantee high reliability under heavy-duty cycle profiles, reducing maintenance intervals and unplanned downtime. Ideal for milling, turning, and grinding centers, the KDA 3.1-100-3-DP0-W1 maximizes spindle performance to deliver superior surface finishes and stringent tolerance control.
