Product Description:

The DDS02.1-W150-DS37-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and included in the DDS Drive Controllers series. As a closed-loop motor controller, it governs synchronous or induction servomotors in automated machinery and provides precise torque and speed regulation for coordinated multi-axis motion. In production systems, it converts regulated DC bus power into controlled motor current so axes can respond quickly to commands from a higher-level control. The unit is part of Line 02 and Version 1 in the series. This makes it suitable for machine tools, handling systems, and other equipment that depends on repeatable axis coordination.

This controller exchanges real-time process data with a PLC over a SERCOS interface, enabling deterministic command and status cycles. This communication method supports synchronized updates between the controller and the automation system during motion. The power stage supplies up to 150 A of continuous output current, allowing large motors to run at rated load without derating. Its housing carries an IP20 protection rating, so live parts are finger-safe when the unit is mounted inside a cabinet. Reliable operation is maintained across an ambient range of 0 – 45 °C, which matches typical control panel conditions. Position and velocity loops obtain rotor angle information from digital servo feedback, avoiding the resolution limits associated with analog transducers.

For thermal management, the drive uses internal air cooling drawn from inside the control cabinet, so no external fan modules are required. Cabinet airflow must therefore be arranged so warm air can move away from the heat sink area. Installations up to 1000 m above sea level can use the unit without current reduction. When equipment is stored or shipped, the controller withstands temperatures from −30 to 85 °C and can return to service after normal power-up conditions are restored. The controller uses Function ID Version 01, which sets the applicable parameter set for this model. This helps keep software setup aligned with the supported control functions of the drive.
