KDA 2.1-050-3-DYS-W1
KDA Spindle Drives
The Bosch Rexroth Indramat KDA 2.1-050-3-DYS-W1 from the KDA Spindle Drives series is a robust KDA Servo Drive designed to deliver precise control in demanding industrial automation environments. This main spindle drive supports 2 axes and operates at a rated current of 50 A, drawing power from a 3-phase, 220-230V AC supply with a DC bus voltage of 300 V. Communication is handled via SERCOS, ensuring deterministic, low-latency data exchange, while the air-cooled design and integrated heatsink fan maintain optimal temperatures across its 0°C to +55°C operating range. Housed in an IP20 protection enclosure, the unit weighs approx. 18 kg and fits within a compact footprint of 350 x 400 x 250 mm.
Engineered for seamless integration, the KDA 2.1-050-3-DYS-W1 features dual D-Sub connectors for encoder feedback and command signals, plus an Aux. Encoder Input with auxiliary and synchronous inputs to support high-resolution motion profiles. A versatile Digital 16-Bit Parallel Speed Command Value interface provides deterministic setpoint control, and the optional RS-232 port on terminal X11 allows secure parameterization and diagnostics. Status is conveyed through dedicated READY (green) and FAULT (red) LED indicators alongside a multi-digit display for real-time monitoring of error codes and operational metrics. The drive’s modular I/O architecture, including connectors X1–X5 for power and control wiring, simplifies installation and streamlines maintenance procedures.
Optimized for spindle and servo motor applications up to 10 kW output, this drive combines high-performance current regulation with encoder-supported closed-loop feedback for smooth acceleration and precise positioning. Its rugged design and front-panel controls enable rapid commissioning and on-the-fly parameter adjustments, reducing machine downtime and improving throughput. Ideal for CNC machining, milling centers, and other high-precision processes, the KDA 2.1-050-3-DYS-W1 delivers reliable power management and advanced motion control in industrial automation systems.
