DDS02.1-W015-DS01-01

The DDS02.1-W015-DS01-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Designed for multi-axis automation stations, the unit modulates power from a regulated DC bus and feeds it to a compatible servo motor. In production lines it coordinates torque, speed, and position through a closed control loop, allowing accurate movement while conserving cabinet space.

This controller exchanges set-point and diagnostic data over the SERCOS interface, so fiber-optic rings can integrate it with a central motion PLC. A continuous output of 15 A defines how much motor phase current the power stage can supply without thermal derating. During repetitive acceleration phases this current margin prevents voltage sag on the shared DC link and keeps power devices within their safe operating area. Thermal energy is expelled by internal air cooling, meaning cabinet airflow must move across the heat sink instead of relying on an external blower. For rotor position and velocity feedback the unit relies on digital servo feedback, allowing single-turn or multiturn encoders to close the position loop directly inside the drive.

Within the DDS architecture the drive belongs to Line 02, and its firmware expects Function ID 01 with Function ID Version fixed to build revision 1. These fixed identifiers lock parameter ranges so replacement units remain electrically interchangeable. The product is classified as a Digital AC Servo Drive Controller, a category that pairs with Indramat MDD, MKD, or similar synchronous motors. Because it remains part of the DDS Drive Controllers series, the module inherits standardized bus rails and front connectors, allowing quick slide-in installation and shared DC link operation with adjacent axes.
