KDA 3.3-050-3-DPS-U1

KDA 3.3-050-3-DPS-U1, Bosch Rexroth Indramat, KDA Spindle Drives delivers precise spindle control with a robust drive design suited for demanding machining applications. This main spindle drive features advanced positioning functions and an extensive speed range, ensuring optimal performance in milling, drilling, and high-precision turning operations. Its stiff control loop and digital command processing minimize oscillations and enhance surface finish quality. Integrated diagnostics monitor drive status in real time, reducing the risk of unexpected downtime.

Incorporating a Rated Current of 50 A and a DC Bus Voltage of 300 V, the unit sustains continuous torque under heavy loads. Cooling is provided by a Forced Cooled by Heatsink Blower system powered from an AC Supply Source for Heatsink Blower of 115 VAC, maintaining stable temperature even at peak output. The drive accepts a Digital 16-Bit Parallel Speed Command Value and supports feedback via an Aux. Encoder Input for spindle or secondary motor signals. Communication with higher-level controls is handled through an Aux. Interface: Serial Interface RS 232 C, while the rugged enclosure conforms to the Design 3 specification in the Series 3 lineup.

Engineers benefit from seamless integration with Bosch Rexroth CNC controllers and PLC platforms, streamlining commissioning and parameter tuning. The drive’s high rigidity, digital control precision, and forced cooling ensure reliable operation in continuous-production environments. Ideal for high-speed spindles and multi-axis machining centers, the KDA 3.3-050-3-DPS-U1 elevates throughput and accuracy in modern manufacturing.
