KDA 3.1-100-3-DQD-U1

KDA 3.1-100-3-DQD-U1, Bosch Rexroth Indramat, KDA Spindle Drives This high-performance main spindle drive delivers precise motion control with exceptional stiffness and positioning accuracy. It supports an extensive speed range with continuous power capabilities, making it an ideal choice for demanding machining applications. Equipped for heavy-duty operation, it maintains stable performance even under rapid speed changes or sustained load conditions. The drive’s robust architecture and advanced electronics ensure reliable, repeatable spindle behavior across a variety of industrial processes.

The unit is rated for a Rated Current: 100 A and operates on a DC Bus Voltage: 300 V backbone, delivering consistent torque for high-inertia spindles. Thermal management is handled by a Cooling: Forced Cooled by Heatsink Blower arrangement, requiring an AC Supply Source for Heatsink Blower: 115 VAC to drive the blower motor. Feedback and synchronization are achieved via an Aux. Encoder Input: With Aux. Encoder Input for 1V Sinusoidal Enc., while motion commands are accepted through an Aux. Interface: Position Command Value Digital 16-Bit Parallel port. Users can also employ the Speed Command Value: Digital 16-Bit Parallel interface for direct velocity control. Internal component layout (Design: 1) and modular construction (Product: KDA; Series: 3) facilitate straightforward installation and service.

Integration into CNC and automation environments is seamless, leveraging industry-standard parallel command protocols. The drive’s fan-forced heat dissipation and high-current bus capability enhance operational reliability, even in harsh workshop conditions. Whether driving milling, grinding, or drilling spindles, the KDA 3.1-100-3-DQD-U1 combines precise control with robust performance for mission-critical applications.
