Product Description:

The DDS02.1-W050-DS27-01 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts command data from the machine control into regulated three-phase output so that connected servo motors operate at the required torque and speed. The device is intended for installation inside a control cabinet, where it serves as the link between the PLC motion kernel and the motor. This arrangement makes it suitable for metal-cutting cells, pick-and-place gantries, and other automated equipment that require coordinated axis control.

The drive is rated for 50 A of continuous output current, allowing the power stage to support normal duty without exceeding its thermal capacity. Communication with the higher-level controller takes place through the SERCOS interface, which uses a fiber-optic ring for real-time setpoints and status exchange in multi-axis systems. The unit uses internal air cooling, so cabinet airflow must remove the switching losses generated by the IGBTs. For position verification, the controller processes digital servo feedback, which supports high-resolution closed-loop operation without an added converter module. The housing has an IP20 rating, so it helps prevent finger contact with live parts but still requires protected cabinet mounting.

The controller is intended for installations up to 1000 m above sea level, where cooling performance remains within the stated operating range. During operation, it supports ambient temperatures from 0 to 45 °C, and when powered down it can be stored between -30 to 85 °C. The parameter structure corresponds to Function ID 01, matching the configuration used for line 02, version 1 units. These limits support use in industrial environments where cabinet-mounted servo electronics must handle varying site conditions and storage climates.
