Product Description:

The DDS02.1-W150-DG02-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. It converts DC bus power from a supply module into regulated three-phase output for a matched servo motor, while processing encoder signals to close the position and speed loops. In modular automation cabinets, this controller forms the axis interface that allows packaging stations, material-handling gantries, and machining centers to execute precise, programmable motion profiles. Because the power stage and feedback processing are combined in one unit, the drive can regulate motor response quickly during acceleration, deceleration, and position correction.

The unit relies on internal air cooling, so ambient air already inside the cabinet is pulled across the heat sink and the enclosure must provide sufficient clearance for airflow. It has a continuous output capability of 150 A, which is the maximum motor phase current the drive can deliver without derating and makes it suitable for high-torque axes. Its housing carries an IP20 rating, which indicates touch-safe openings but no protection against sprayed liquids, so enclosure mounting is required. Reliable operation is maintained across ambient temperatures of 0 to 45 °C when cabinet cooling is present. Command and diagnostic data from the motor arrive through digital servo feedback, enabling fine current vector control and high-resolution position monitoring.

When the machine is powered down, the electronics and power devices remain stable in storage temperatures from -30 to 85 °C, allowing safe shipment or warehouse staging without climate-controlled rooms. Installation altitude is limited to 1000 m because thinner air above that height reduces heat dissipation and requires current derating. The controller is Version 1. It belongs to Line 02 in the DDS series. This storage range also supports transport and extended indoor storage before installation.
