Product Description:

The DDS02.1-W015-RS04-00 digital servo drive is built by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. In a motion system, this unit converts low-level command data into regulated output currents for matched Indramat motors, providing closed-loop torque, speed, and position control in machine tools, packaging stations, and material-handling axes. Its compact card format slides into a modular drive rack where multiple axes share a common DC bus, which helps keep multi-axis installations organized inside the cabinet.

Command and status data are transferred over the SERCOS interface, giving deterministic fiber-optic communication between the drive and the central motion controller. The power stage delivers a continuous phase current of 15 A, so axes within the drive’s output range can accelerate without overcurrent tripping. The unit is part of Line 02 in the DDS family. Thermal energy is removed by internal cabinet air cooling, so the enclosure must provide steady airflow across the module rather than rely on a fan mounted on the drive itself. An IP20 housing restricts access to live conductors and requires installation inside a control cabinet. Operation is permitted in ambient temperatures from 0 to 45 °C, matching typical climate-controlled industrial spaces.

The drive accepts rotor position information through resolver feedback, enabling sinusoidal current control without requiring an optical encoder. It maintains its electrical ratings up to 1000 m above sea level, so most facilities can use it without altitude-related derating. For storage and transport, the electronics can withstand temperatures from -30 to 85 °C without condensation, which helps protect the circuit boards when the unit is not energized. The drive is Version 1, identifying the revision used for this model.
