DDS02.2-A100-BE33-01-FW

The DDS02.2-A100-BE33-01-FW is a drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It converts DC bus energy from a shared supply into controlled three-phase output so that connected servomotors follow precise command values. Within industrial automation lines this unit forms the axis amplifier, closing the speed and position loops required for coordinated motion in material handling, printing, or pick-and-place stations. It supports both synchronous and asynchronous motors and includes diagnostic LEDs for rapid status checks.

The controller communicates with the master via the SERCOS interface, an optical ring that transmits real-time setpoints and feedback at high baud rates. Its power stage is rated for 100 A, allowing it to drive medium-frame motors that demand substantial peak current during acceleration. Thermal limits are managed by Air, from outside control cabinet (external) cooling, meaning ambient air is drawn through the housing instead of recirculating warm cabinet air. Position signals are processed through Digital servo feedback, while a resolver channel offers redundancy; these encoded values are sampled and forwarded in every SERCOS telegram. Hardware Version 2 adds expanded parameter memory so that application data stays resident after firmware updates.

Operational characteristics that depend on software are supplied separately, because Firmware must be ordered as a separate subitem; this lets users select the exact feature set required for each machine. Drive behavior is locked by the 01 function ID version, ensuring uniform response curves across replacements, and cabinet integration aligns with series 02 line dimensions. As a Digital AC Servo Drive Controller, the module also accepts resolver feedback, stores tuning parameters in non-volatile memory, and interlocks with system safeties through configurable I/O.
