Product Description:

The DDS02.1-W015-RA01-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. It converts low-level command signals into controlled three-phase motor output for regulating the speed, torque, and position of connected servo motors. The module plugs into a modular power supply rack and shares a common DC bus with neighboring drives. Closed-loop regulation allows the controller to respond to changing loads during acceleration, deceleration, and holding phases. This arrangement supports coordinated axis control in pick-and-place heads, conveyors, servo presses, and machining modules installed in central control cabinets.

The drive exchanges reference values through an analog interface, so a ±10 V command from a PLC can directly set the operating point. Its power stage supplies 15 A of continuous current, which suits medium-frame Indramat motors used in steady-duty applications. Heat from the power section is removed by internal cabinet airflow rather than external ducting. Personnel safety is supported by an IP20 housing, which helps prevent accidental finger contact and requires installation inside an enclosure. Reliable commutation is handled with resolver feedback, and the electronic sections maintain rated accuracy within an ambient range of 0 to 45 °C. The resolver signals also provide the rotor position information needed for stable control at low and changing speeds.

Installation sites can be located up to 1000 m above sea level without current derating or changes to the cooling method. For storage or transport, the electronics tolerate temperatures from -30 to 85 °C, which helps protect the unit during seasonal shipping and warehouse conditions. The unit carries Function ID 01 and belongs to line 02. It is supplied as version 1, so its parameter numbering and diagnostic code format remain consistent with other first-generation controllers in the same product family.
