Product Description:

The DDS02.1-K025-D belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As a modular axis amplifier, it sits between the shared supply module and a matched servo or induction motor, receiving motion commands from a PLC or CNC and regulating phase current accordingly. By executing closed-loop control inside the cabinet, the controller maintains commanded torque, speed, and position on packaging lines, assembly stations, and machine tools. Its control functions are integrated in the drive, so the cabinet does not need separate external regulators for routine axis operation.

The controller can deliver a continuous output of 25 A, providing adequate current for mid-frame motors in multi-axis systems. Its housing meets the IP20 protection category, so the installation cabinet must provide the dust and splash shielding that the device itself does not. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, and additional airflow may be needed near the upper end of that range to prevent thermal derating. Position data are processed through digital servo feedback, which supports accurate interpolation and avoids the offset issues associated with analog feedback signals. Mounting is permissible at elevations up to 1000 m above sea level, and the unit is part of Line 02, so its connector placement and frame depth match other second-generation DDS modules.

When the drive is stored or transported, the electronics tolerate temperatures from −30 to 85 °C, allowing warehouse storage without damage when the unit is not in operation. The unit is Version 1, which keeps parameter handling and diagnostics consistent with matching drives in the same release. Classified as a Digital AC Servo Drive Controller, it exchanges current commands and status data over the same system bus used by companion drives. That shared bus structure simplifies wiring between multiple axes and the central control hardware.
