Product Description:

The DDS02.1-W050-RL02-01-FW drive controller is produced by Bosch Rexroth Indramat for multi-axis automation systems. It is a digital AC servo drive controller that works between an Indramat supply module and a synchronous or asynchronous servo motor. In operation, the unit regulates torque, speed, and position for one mechanical axis by processing command values and motor feedback in a closed loop. This arrangement lets the controller serve as the power and control stage for precise machine motion. It converts supply power into controlled motor output during repeated production cycles. That role makes it suitable for automated machinery that requires stable servo regulation and coordinated sequencing from a higher-level controller.

The controller has a rated output of 50 A, so the power supply and cabling must support continuous current at that level. Motion commands are handled through single-axis position control, which means the device is intended to manage one axis rather than coordinate several axes internally. Motor feedback is read through resolver feedback, allowing the controller to calculate rotor position and speed from the connected transducer. Heat is removed by internal cabinet air cooling, so the enclosure must maintain airflow to avoid thermal derating during operation. Cabinet ventilation therefore remains important when the drive operates under sustained load.

The controller carries Function ID 01, belongs to Line 02, and uses Version 1 for this product variant. These identifiers indicate the design line and revision level and affect connector arrangement and compatible option support. In a larger drive system, the unit works with separate supply hardware and external motion control rather than serving as a standalone multi-axis controller. Its digital processing helps maintain repeatable response during speed changes and varying load conditions.
