KDA 3.3-100-3-L0D-W1

KDA 3.3-100-3-L0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives is a robust main spindle drive designed for precision machining and industrial spindles. Its compact chassis houses advanced power electronics and high-stiffness components, delivering continuous torque with minimal mechanical compliance. The drive's architecture emphasizes smooth speed transitions and precise positioning, ensuring consistent performance across its entire operating range. Integrated diagnostic interfaces and fault indicators allow rapid fault isolation and maintenance planning, reducing unscheduled downtime.

Featuring a Rated Current of 100 A and a DC Bus Voltage of 300 V, the unit sustains high dynamic loads and supports a broad speed spectrum. Forced cooling is handled by a Cooling system with a dedicated AC Supply Source for Heatsink Blower of 220 VAC, maintaining stable thermal conditions even under peak output. Command signals are received via a Speed Command Value input over the SERCOS - Interface, while position feedback utilizes a Position Command Value Digital 16-Bit Parallel Aux. Interface. The drive omits an auxiliary encoder input (Aux. Encoder Input>: Without) to streamline configuration, and its Design emphasizes modularity for easy integration into multi-axis systems.

Engineers will appreciate the KDA 3.3-100-3-L0D-W1's seamless compatibility with standard spindle motors and SERCOS networks, enabling plug-and-play integration within existing CNC architectures. Its forced-air heatsink blower design enhances reliability by preventing thermal overloads in continuous-duty applications. Ideal for high-precision milling, turning, and grinding operations, this spindle drive optimizes machine uptime, repeatability, and machining quality.
