Product Description:

The DDS02.1-W025-DS24-04-FW is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It is a digital AC servo drive controller used to supply regulated three-phase power to matched servomotors. In industrial automation cells, it receives motion commands from higher-level control systems and converts them into controlled motor output for positioning and speed regulation. The controller is intended for cabinet-mounted servo systems where accurate axis response and stable closed-loop motion are required during normal machine operation.

The drive delivers a continuous output of 25 A, which is the current the power stage can sustain during normal operation without thermal derating. Heat is removed by air drawn from inside the control cabinet, so the enclosure must provide steady internal airflow around the unit and must not trap hot exhaust near the heat sink. An enclosure classification of IP20 limits the controller to protected indoor panels and provides basic finger-safe protection rather than resistance to dust or water. The permitted ambient temperature range is 0 to 45 °C, and the installation altitude is limited to 1000 m above sea level to preserve cooling effectiveness and insulation performance.

System integration is handled through the fiber-optic SERCOS interface, which provides deterministic cycle timing for coordinated multi-axis motion and reliable data exchange with the higher-level controller. Rotor position data returns via digital servo feedback, allowing the controller to close velocity and position loops without external converters and to react quickly to command changes. The drive requires separately ordered firmware in its memory before operation. For storage or shipment, the unit can remain between -30 to 85 °C without damage to electronic components, making it suitable for unpowered transport and warehouse storage.
