Product Description:

The DDS02.1-W050-DA02-01-FW drive controller is built by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Housed inside a control cabinet, it serves as the intermediary between a motion processor and a servomotor, shaping current and voltage so industrial axes can follow programmed velocity and position profiles. The cabinet-mounted format keeps the power electronics separate from the motor while allowing higher-level control hardware to send motion commands directly to the axis. This design supports coordinated motion in machining cells, handling gantries, and printing lines where rapid response and stable axis control are required.

The unit exchanges command data through an analog interface, allowing standard ±10 V speed or torque references from PLCs and CNC cards. Thermal energy is removed by internal air cooling, so cabinet airflow must be maintained to keep heat sink temperatures within limits. During continuous operation, the power stage can deliver a rated current of 50 A, which allows it to drive medium-frame servomotors without derating. Position verification relies on digital servo feedback, and the encoder signal is read directly by the controller for precise rotor alignment. This arrangement lets the drive close the control loop at the axis with accurate speed and position response. The unit is a Digital AC Servo Drive Controller, so PWM output, fault monitoring, and parameter storage are handled by microprocessor-based circuitry.

The internal parameter structure is tied to Function ID 01, and the drive belongs to Line 02. Hardware Version 1 identifies the first version of this DDS02.1 configuration. These codes distinguish this unit from other DDS variants that use different interface or power-stage combinations. The version code refers to the controller configuration rather than to the commanded motion profile.
