Product Description:

The DDS02.1-W050-DL22-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Mounted between a compatible power supply module and an Indramat synchronous motor, it translates velocity and position commands from higher-level motion controllers into regulated three-phase current. Within automated cells, this device provides closed-loop drive control so that a single mechanical axis follows programmed profiles with repeatable accuracy. Because current regulation occurs inside the controller, the connected motor can respond quickly to command changes and load disturbances during repeated motion cycles. This arrangement also helps the drive maintain stable torque production during acceleration, deceleration, and holding phases.

Position instructions enter the drive through the single-axis position control interface, allowing the axis to run independently of neighboring modules in a multi-axis cabinet. During continuous duty, the controller can deliver 50 A to the motor windings, so associated conductors and protection devices must support that load. Thermal energy produced by the output stage is removed by air from inside the control cabinet, which means enclosure airflow must pass across the heat sink. Exposed surfaces carry an IP20 rating, so the unit must be installed inside a grounded electrical enclosure. Rotor angle is returned through digital servo feedback, enabling the regulator to correct position and speed deviation during operation.

The allowable ambient range of 0 to 45 °C supports full output during operation, while storage is permitted from -30 to 85 °C when the controller is not energized. Installation is permitted up to 1000 m above sea level before additional cooling or insulation measures are needed. The unit carries Function ID 01, which identifies the application class used by this controller. It is built in line 02 and version 1, keeping connector arrangement and diagnostic behavior aligned with the matching DDS platform. These operating limits should be considered when planning cabinet ventilation and installation height.
