KDA 3.3-050-3-AQD-U1

KDA 3.3-050-3-AQD-U1, Bosch Rexroth Indramat, KDA Spindle Drives series main spindle drive delivers precision motion control with exceptional rigidity and dynamic performance. Designed for demanding machining applications, it offers continuous power transmission across an extensive speed range and incorporates advanced positioning features for accurate contouring. The unit’s robust DC Bus Voltage of 300 V and a Rated Current of 50 A ensure consistent torque output under varying loads. Forced cooling by a dedicated Cooling blower maintains optimal thermal stability even during prolonged high-speed operation.

Incorporating an AC Supply Source for Heatsink Blower rated at 115 VAC, the drive guarantees reliable heat dissipation via its heatsink blower system. An integrated Aux. Encoder Input supports 1 V sinusoidal encoder signals for high-resolution feedback, while the Aux. Interface offers a Position Command Value Digital 16-Bit Parallel input for precise trajectory control. Speed setpoints are managed through an Speed Command Value interface of Analog +/- 10V, enabling smooth acceleration profiles and fine speed adjustments. The drive conforms to Design level 3 within the Product family and aligns with Series 3 specifications for simplified integration into existing KDA frameworks.

Engineers benefit from seamless integration with CNC controllers and PLCs, leveraging the drive’s digital and analog control channels for synchronized spindle operation. The compact form factor and modular configuration reduce installation time, while the forced-cooled heatsink blower enhances reliability in continuous-duty cycles. Ideal for high-precision milling, turning, and grinding centers, the KDA 3.3-050-3-AQD-U1 combines rugged design with advanced control to optimize productivity and uptime.
