Product Description:

The DDS02.2-W100-BA03-01-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a digital AC servo drive controller, it supplies regulated power to compatible servo motors and exchanges status data with higher-level PLCs so automated axes can follow position and speed commands. In a machine control system, it serves as the power stage between the cabinet supply and the motor while supporting closed-loop motion control. The controller responds to changing command signals during acceleration, deceleration, and steady-speed operation in packaging, handling, and other industrial equipment that depends on repeatable axis movement.

This controller communicates through an analog interface, allowing continuous signal modulation for torque and speed references. To remove internally generated heat, it uses internal air cooling, so airflow is taken from inside the control cabinet and routed across the heat sink. The power section is rated for 100 A of output current, so conductor sizing and protection devices must match that load. Electrical parts are protected to IP20, which guards against finger contact and objects larger than 12.5 mm. The permitted ambient operating range is 0 to 45 °C; above this range, the drive must be derated or provided with additional cooling.

During extended shutdown or shipping, the drive may be stored from -30 to +85 °C if temperature changes remain gradual enough to prevent condensation. Installation altitude is limited to 1000 m so internal temperatures and insulation performance remain stable as cooling air becomes less dense. The controller can process digital servo feedback or resolver signals, which gives flexibility when pairing it with different motor types. Resolver support is useful for motors that return analog rotor signals, while the encoder-based option supports direct electronic position feedback. The unit is part of Line 02 and uses Function ID 01 with Version 2.
