Product Description:

The DDS02.1-W025-DL41-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It forms the closed-loop link between a motion control system and a servo motor, regulating current and voltage so programmed moves are carried out with precision. In automated lines, the controller supplies drive signals, processes motor feedback, and manages dynamic braking so a single machine axis can accelerate, decelerate, and hold position as commanded by a PLC or CNC. This type of control is commonly used on feed axes, slides, and indexing mechanisms where repeatable motion is required.

This model delivers a continuous phase output of 25 A, which is the motor current the power stage can sustain continuously without thermal overload. The housing has an IP20 rating, which provides finger-safe protection for live parts and requires cabinet installation. Internal heat is removed by air from inside the control cabinet, so cooling depends on enclosure airflow rather than an external blower. Reliable operation is specified for ambient temperatures from 0 to 45 °C, which suits typical industrial enclosures. Motion data returns to the drive through digital servo feedback, allowing fine velocity and position control when the unit is paired with compatible motors. That feedback path helps the controller correct for load changes during acceleration, deceleration, and settling at standstill.

The command layer uses single-axis position control, which suits applications built around one mechanical axis. It is appropriate for machines where one servo axis is controlled independently rather than through a coordinated multi-axis module. Installation is permitted up to 1000 m above sea level without adjustment to current or switching frequency. When production pauses, the electronics can be stored at temperatures from -30 to 85 °C without damage to components or parameter memory. Application-specific behavior is loaded through firmware, and it must be ordered as a separate subitem.
