Product Description:

The DDS02.1-A050-RA01-00/S002 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It supplies regulated power and closed-loop control to synchronous or induction servo motors used in automated machinery and handling systems. In multi-axis cabinets, it serves as the power stage between the DC bus and the motor, while the internal regulator handles current, speed, and position response. The module belongs to Line 02 and is Version 1, so it fits DDS installations that use the same bus structure and operating scheme.

In normal operation, the controller delivers a continuous output of 50 A, a current level suited to medium-torque axes on packaging, printing, or material-forming lines. Command data reach the regulator through an analog interface, allowing setpoint voltages from legacy motion PLCs to be processed without protocol conversion. Rotor position is returned through resolver feedback, so commutation and velocity loops can continue to function in electrically noisy locations. To avoid heat accumulation, the unit relies on external air cooling, which means airflow from outside the control cabinet passes across its heat sink. Power sections, control electronics, and the terminal area are protected by an IP20 housing intended for installation inside a larger protective enclosure. This combination suits systems that use conventional analog commands and separate motor feedback rather than fieldbus-based control.

The drive maintains rated accuracy within an operating range of 0 to 45 °C, and it can be stored de-energized between -30 to 85 °C without damage to passive or active elements. Altitude capability reaches 1000 m above sea level before output derating is required. The unit carries Function ID 01, which fixes the operating function used by this controller type. Storage and altitude limits should be observed so thermal margin and insulation performance remain within the intended operating range.
