Product Description:

The DDS02.2-W015-BE21-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It belongs to line 02 and is supplied as version 2, allowing it to fit modular multi-axis racks that share a common power supply. In an automation cell, the unit regulates the torque, speed, and position of connected servo motors, forming the closed-loop link between a motion control PLC and the mechanical load. Its module format also suits cabinet layouts where several coordinated axes are installed side by side.

The controller delivers a continuous output of 15 A, so the power stage can supply steady motor phase current during normal operation. An enclosure rating of IP20 limits installation to clean, protected cabinets while still permitting convection airflow. Command and status data are exchanged over the SERCOS interface, giving deterministic, fiber-optic communication with centralized controls. For position feedback, it accepts digital servo feedback and resolver feedback, so the drive can work with either encoder-based or resolver-based motor systems. The permissible ambient range of 0 – 45 °C covers most indoor machinery environments and helps keep the electronics within normal operating conditions.

Heat removal is achieved through internal air cooling, meaning cabinet air is drawn across the heat sink and exhausted back into the enclosure without external ducts. The drive may be mounted up to 1000 m above sea level, where standard cooling performance is maintained. When equipment is powered down, the unit can be stored between −30 – 85 °C, allowing transport and warehousing in unconditioned spaces. The drive requires a separate firmware subitem so the control functions match the intended machine task.
