Product Description:

The DDS02.1-W050-DA14-01-FW is a digital AC servo drive controller in the DDS Drive Controllers series from Bosch Rexroth Indramat. It regulates power between a supply unit and a compatible synchronous or induction motor so the axis can follow commanded speed and torque values from a higher-level PLC. In automated equipment, this lets the drive respond to rapid load changes without forcing the controller to manage low-level current regulation. By closing the current loop inside the module, the drive supports stable motor behavior during acceleration, deceleration, and steady-state operation.

This controller supplies a continuous output of 50 A, which is the motor phase current it can deliver without thermal derating under normal operating conditions. Command signals are received through an analog interface, allowing analog velocity or torque references to be converted directly into PWM control for the inverter stage. Heat is removed by air from inside the control cabinet, so the installation must provide steady airflow across the heat sink instead of relying on a sealed enclosure with stagnant air. The housing is rated IP20, which protects against accidental contact with live parts but is not intended for direct exposure to dust or liquids. Ambient air should remain within 0–45 °C to keep thermal behavior and controller operation within the intended range.

Position and speed signals are processed through digital servo feedback, allowing the drive to calculate control error quickly for accurate motor regulation and smooth response to changing load conditions. The controller is intended for operation at elevations up to 1000 m, where cooling performance and insulation characteristics remain within its stated limits. For storage, the unit can remain within -30–85 °C when it is not in use, helping protect electronic components before installation. The required function set is installed in the slot reserved for Function ID Version 01, allowing the drive to be matched to the axis application.
