Product Description:

The DDS03.1-W030-R is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed for cabinet installation, it interfaces with companion motor modules to regulate velocity and torque loops in automated machinery. By processing position signals and modulating output power, the unit links the motion control system to the mechanical load in assembly lines, packaging cells, and handling stations. This arrangement supports closed-loop axis control without requiring a separate standalone regulating stage at the motor.

The drive delivers a continuous phase output of 30 A, so steady-state motion and acceleration duty can be sized around that current level. The housing relies on internal air cooling, meaning it uses air already present inside the control cabinet and does not require external ducting. A protection rating of IP20 restricts the controller to clean, dry enclosures while still preventing accidental finger contact at the shielded terminals. For position verification, the device reads resolver feedback, which returns rotor angle signals for closed-loop regulation across the speed range. Safe continuous service is specified for ambient temperatures from 0 to 45 °C. The controller is intended for cabinet-mounted installations where airflow, enclosure protection, and feedback compatibility are planned together with the rest of the axis hardware.

Operation is permitted up to 1000 m elevation, so no derating is required for most factory floors. When power is removed, the electronics can be stored or transported in climates from -30 to +85 °C without damage to passive or semiconductor elements. The product is part of Line 03 and is Version 1. These identifiers keep the controller in the correct product revision for compatible mounting interfaces and parameter sets.
