Product Description:

The DDS02.1-W025-DS01-01 is a servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Intended for cabinet-mounted motion axes, the unit converts command data from higher-level controls into regulated three-phase power for compatible Indramat synchronous motors. In a multi-axis system, it acts as the power stage between the control platform and the motor, translating motion commands into controlled current output. That controlled output allows coordinated motion profiles to be followed with repeatable response during indexing, transfer, and positioning tasks.

Communication with the machine control is established through a SERCOS interface, allowing real-time cyclic data exchange between the controller and the drive. During operation, the unit maintains a rated phase output of 25 A, which is the continuous current available to the connected motor without derating. This output suits mid-size axes that need steady torque during repeated starts, stops, and synchronized moves. Heat is removed by air from inside the control cabinet, so cabinet ventilation must carry away the dissipated losses. The enclosure has an IP20 protection category, which provides finger-safe access but does not seal the interior against moisture. Rotor position is reported through digital servo feedback, supporting high-resolution velocity and position loops without additional encoders.

The device can be installed up to 1000 m above sea level without output reduction, and it operates in ambient temperatures from 0 – 45 °C. When powered down, the electronics can be stored between -30 – 85 °C. Control behavior is tied to Function ID 01, which keeps the drive aligned with the intended control configuration. The product is part of line 02 and version 1, identifying the design generation used for this model. Storage across this temperature range allows the unit to remain protected during transport or warehousing before installation. These limits are important when the unit is mounted beside other heat-producing devices in an enclosed control cabinet.
