DDS03.1-W30-R

The DDS03.1-W30-R drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series is a precision digital AC servo drive controller designed for high-performance motion tasks. It accepts a nominal **24 Volts DC** input and delivers a continuous **30 Amps** rated current to the motor. The controller utilises a **300 Volts DC** bus voltage to feed power electronics optimized for dynamic response. Native resolver-based feedback ensures tight loop control for rotary and linear motors.

Mechanically, the unit measures **355 × 325 × 70 millimeters** and weighs **5.5 kilograms**, making it a compact solution for space-constrained cabinets. Its **IP20** rated housing permits vertical installation inside a control enclosure, with internal **air cooling** provided via bottom cold air inlets and top hot air outlets. Bosch Rexroth recommends **40 millimeters** of clearance at the front and **80 millimeters** above and below to maintain ambient temperatures between **0 … 45 °C**. The controller is identified as **Line 03, Version 1**, with a printed barcode sticker listing all key data for commissioning and spare ordering.

Seamless integration with LAR, LAF, MDD and MKD series motors simplifies system design and tightens motion synchronisation. The robust internal cooling scheme and IP20 protection deliver reliable operation in demanding industrial environments. As part of the DDS series, the DDS03.1-W30-R offers precision, consistency and ease of maintenance for modern automation applications.
