Product Description:
The KDA 2.1-050-3-DYS-U1 spindle drive is developed by Bosch Rexroth Indramat to serve industrial automation functions. This model accepts ±10 V analog reference for torque or speed regulation. It enables indexing and spindle orientation through C-axis features. It offers coordinated motion through master-follower configuration capability.
The KDA 2.1-050-3-DYS-U1 spindle drive supplies a steady 50 A output current. Its output section uses a transistor-based amplification circuit. The Built-in thermal sensors detect overload and activate automatic shutdown. Its external airflow is powered by a 230 V AC cooling fan input. The dive requires upright mounting in enclosed electrical cabinets. Its Ventilation spacing is essential for maintaining airflow efficiency. Its operating environment must remain between 0°C and 45°C. The casing design allows installation in rack or panel assemblies. The input voltage range includes three-phase 230/400 V AC with a 10% margin. It includes a response system for short-circuit conditions as a protection feature. Its Integrated self-checks handle voltage levels and internal malfunction reports. Position feedback is accepted from resolver-based sensor encoders. The signal transmission uses direct analog wiring with no network interface. This model does not use any digital communication protocol.
The KDA 2.1-050-3-DYD-W1 spindle drive is tailored for machining equipment. It matches well with Bosch Rexroth 2AD motor systems in machine tools. Acceleration and braking curves are modified through internal slope control. It handles rotary spindle positioning for complex cutting operations. The speed and torque settings can be managed by external analog units. Its analog interface allows simple connection with conventional controllers. The Air-based heat dissipation ensures thermal control during extended use. It is compatible with systems requiring velocity and torque-based control. Its design typically conforms to the IP20 ingress protection class. The safety features monitor critical faults and manage the risk of component failure.
