Product Description:

The DDS02.1-A150-DA01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. As a drive controller, it supplies regulated current and velocity commands to compatible servomotors, forming the closed-loop axis modules used in machining centers, packaging lines, and material-handling cells. It works as the power stage between the machine control and the motor, converting incoming commands into controlled motor response during speed and position changes. The unit carries Function ID 01 and belongs to Line 02, which places it within the second DDS design line for analog command applications.

This unit delivers a rated current of 150 A, giving it the capacity to energize medium-to-high torque motors without current foldback during dynamic moves. Its protection housing is classified as IP20, so it must be mounted in an enclosed cabinet to reduce exposure to dust and accidental contact. Thermal management uses air from outside the control cabinet, meaning fresh airflow passes across the heat sink and exits the enclosure instead of recirculating warm air. Command and diagnostic signals enter through an analog interface, making it suitable for legacy PLCs that issue ±10 V speed references. Rotor position is returned through digital servo feedback, allowing high-resolution commutation and tight velocity control. This combination supports accurate speed regulation while still accepting conventional analog control signals from existing machine systems.

Ambient service limits extend from 0 to 45 °C, supporting full-load operation on the factory floor without derating. When powered down, the electronics remain intact across storage temperatures of -30 to 85 °C, which supports warehouse storage before installation. Installation is permissible up to 1000 m elevation, matching standard plant altitudes without extra cooling measures. The controller is built as Version 1, which maintains compatibility with established rack layouts while using the diagnostics assigned to this revision.
