Product Description:

The DDS02.1-W050-DS09-01-FW is a drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series for AC servo axes in multi-axis automation. It is intended for cabinet installation on a shared DC bus, which allows several DDS units to operate together in coordinated motion systems. In automated machinery, the controller converts bus power into regulated motor current so connected servo axes can follow commanded movement. Within the product line, the unit belongs to Line 02, carries Function ID 09, and is Version 1.

Communication with higher-level control is handled through the SERCOS interface, which supports cyclic transmission of velocity, torque, and position commands. This allows a central motion controller or PLC to synchronize the axis with other drives on the network. A continuous output current of 50 A indicates the motor phase current the drive can supply during normal operation without thermal derating. Heat is removed by internal air cooling, with cabinet air moving across the heat sink rather than through external ducting. The housing has an IP20 protection class against accidental contact, and the drive is intended for ambient temperatures from 0 to 45 °C. Because the cooling air is taken from the enclosure interior, the cabinet should provide unobstructed airflow around the unit.

Installation is permitted up to 1000 m above sea level without output reduction, and storage is allowed from -30 to +85 °C when the unit is not operating. Motor position and speed are exchanged through digital servo feedback, allowing the controller to close the servo loop with compatible encoder-equipped motors. This feedback path supplies the drive with the information needed for precise speed regulation and position control during operation. Altitude and storage limits should be observed in enclosed industrial installations where several axes share the same cabinet space.
