Product Description:

The DDS02.1-W150-DS24-03-FW is a drive controller manufactured by Bosch Rexroth Indramat in the DDS Drive Controllers series. Serving as a digital AC servo drive controller, it converts high-level motion commands into regulated three-phase output for synchronous or induction servo motors on automated machinery. Within an automation cell, the unit coordinates torque and speed so each axis follows the motion profile sent by a supervisory PLC or CNC with repeatable accuracy. This type of controller is used where closed-loop motor control is needed for positioning, speed regulation, and coordinated motion on production equipment. It forms the power and control stage between the machine command system and the connected motor.

A fiber-optic communications port using the SERCOS interface lets the controller exchange real-time setpoints and feedback with the motion master over a deterministic bus. The power stage supplies up to 150 A of continuous output current, which suits high-torque motors that accelerate heavy loads. Heat is removed by air from inside the control cabinet, so cabinet airflow must be maintained to avoid thermal derating. The housing has an IP20 rating, which provides finger protection but no sealing against water, so the unit is intended for clean, dry enclosures. Reliable operation is permitted between 0 to 45 °C, keeping the electronics within their intended temperature range on the factory floor. Position verification comes from digital servo feedback, allowing high-resolution encoder data to close the velocity and position loops without external converters.

Installation limits include a maximum mounting altitude of 1000 m, where the cooling assumptions for cabinet operation remain valid. When the machine is idle or in transit, the hardware tolerates ambient temperatures from -30 to 85 °C, which helps protect the circuitry during storage or shipping. The drive is part of Line 02, and application software is supplied separately for the required control task. The altitude limit applies to mounted operation rather than storage. The storage temperature range applies when the unit is not operating.
