KDA 2.1-050-3-AYS-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-AYS-W1 spindle drive is a high-performance member of the KDA Spindle Drives series, engineered to offer precise velocity and torque control in demanding industrial automation environments. Weighing Approx. 20 kg, this drive operates on a 220V/50-60Hz AC Supply Source (3-phase) and features air cooling through a forced heatsink blower for sustained thermal stability. With a Rated Current of 050 A and a Bus voltage of 300 V on a DC Bus Voltage Type, it delivers consistent power delivery under continuous load cycles. Communication is provided via an Serial interface RS 232 C for configuration, supplemented by analog or SERCOS protocols for real-time speed and position feedback. The compact mechanical design facilitates integration into a variety of rack-mounted and panel installations.

Technical specifications of the KDA 2.1-050-3-AYS-W1 are comprehensive and clearly defined. The drive supports Analog +/- 10 V Speed Command Value input and implements Analog velocity/torque control for smooth acceleration profiles. Auxiliary and synchronous signals are accommodated through the Aux Encoder input, enabling precise motor position monitoring. This unit is designed to interface directly with MAC and MK series motors, ensuring broad compatibility across Bosch Rexroth Indramat spindles. The external fan cooling system provides forced convection under the Cooling Method parameter, maintaining optimal junction temperatures during high-duty cycles. The drive’s bus voltage rating of 300 V DC is stabilized by integrated line filters and surge suppression components.

In operation, the KDA 2.1-050-3-AYS-W1 maintains excellent dynamic response thanks to its high-bandwidth control loop and low inertial coupling with connected motors. Thermal management is achieved via the dedicated heatsink blower, which sustains drive performance even under prolonged peak loading. The analog control interface affords smooth spindle acceleration and deceleration, minimizing mechanical shock and extending bearing life. With its robust design, the drive resists performance degradation in industrial environments, offering reliable operation across temperature and humidity variations. The drive’s modular architecture simplifies maintenance and reduces mean time to repair (MTTR) in the event of component replacement.

System integration is streamlined through standard RS-232C connectivity and support for both analog and SERCOS interfaces, enabling seamless incorporation into CNC, milling, and grinding machinery. The precise speed and torque control functions make this drive ideal for high-speed spindle applications, precision machining centers, and automated production lines requiring consistent spindle dynamics. Engineers can leverage parameter configuration tools to tailor performance envelopes to specific process requirements, while the robust mechanical footprint ensures compatibility with existing cabinet designs. Overall, the Bosch Rexroth Indramat KDA 2.1-050-3-AYS-W1 represents a turnkey solution for industrial automation systems demanding high reliability, precision, and integration flexibility.
