Product Description:

The DDS02.1-W015-RL02-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. In an automation cabinet, it converts DC bus energy into three-phase current so a servo motor can follow programmed motion profiles. By closing the torque and velocity loops internally, the unit reduces the processing load on the central PLC and supports deterministic motion in material handling, packaging, and light machining applications. This local control approach helps maintain smooth acceleration, stable speed regulation, and repeatable stopping behavior on coordinated machine axes. It is intended for cabinet-based servo systems that need predictable axis response without placing every control task on the higher-level controller.

This controller operates with a rated output of 15 A, supplying continuous phase current for medium-power synchronous motors used on secondary axes. Cooling uses air intake from inside the control cabinet, so the surrounding panel must manage internal airflow around the heat sink and adjacent power components. The housing has an IP20 rating, which means the unit is intended for installation inside a closed panel rather than direct exposure on the machine. Command exchange is handled through a single-axis position control interface, allowing the motion system to send direct position commands to the drive. Reliable operation is maintained across an ambient range of 0 to 45 °C, and the product is part of Line 02.

Installation is permitted up to 1000 m above sea level before additional derating measures are required. When the drive is not operating, it can be stored between -30 to 85 °C without harming internal components during transport or indoor storage. Position and speed loops use resolver feedback, which provides stable rotor angle information and supports low-speed operation where signal robustness is important. This feedback method also resists electrical noise better than many purely digital sensing arrangements in harsh industrial environments. The unit is version 1, matching the parameter structure and diagnostics used by first-generation DDS controllers.
