Product Description:

The DDS02.2-W200-BE21-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed between the motion control system and a synchronous or induction motor, it modulates current and voltage so the motor follows position or velocity commands in automated machinery. By matching the current loop response to the attached motor and load, the unit maintains precise axis performance in packaging cells, printing lines, and material-handling stations.

This controller can deliver a continuous output of 200 A, allowing it to run medium-to-high power servo motors without current derating inside its specified thermal window. Command and diagnostic data are exchanged over the SERCOS interface, which standardizes cyclic setpoint transfer and real-time status reporting between multiple drives on the same fiber-optic ring. Component ingress protection is rated at IP20, so the device must be mounted in a control cabinet where only limited dust contact is expected. Safe operation is specified for ambient temperatures between 0 to 45 °C. Within this range, the drive uses internal air cooling, so cabinet airflow handles heat dissipation instead of an attached heat sink.

The permitted installation height is up to 1000 m above sea level, allowing full current capability before thinner air reduces convection inside the enclosure. Position and speed loops can be closed with digital servo feedback or resolver feedback, so the unit can work with older resolver-equipped motors or newer encoders that transmit serial data. During extended storage or transport, the electronics remain stable between -30 to 85 °C, which allows flexible handling before installation. The unit is part of product Line 02, which identifies its design line within the series.
