Product Description:

The DDS02.1-A150-DA02-00 drive controller is manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As a digital AC servo drive controller, it governs three-phase servo motors in automated machinery, translating motion commands into regulated current so that positioning, velocity, and torque targets are met under closed-loop control. Its control loop continually compares commanded values with returning motor data, helping the axis remain stable when load and speed conditions change during operation. This type of drive is commonly used on machine axes that need controlled acceleration, repeatable stopping behavior, and consistent speed regulation through changing duty cycles.

The controller can supply a continuous output of 150 A, which is the maximum steady-state current available to the connected motor windings. Command data enter through an analog interface, enabling the drive to follow reference voltages or currents generated by a PLC or motion card. Rotor position signals return via digital servo feedback, giving the controller high-resolution information for precise speed and position regulation. That feedback channel allows the drive to correct speed error and maintain repeatable positioning during changing load conditions. Thermal management uses external air cooling, which moves ambient air from outside the cabinet through a managed airflow path to remove loss-generated heat. An enclosure rating of IP20 provides finger-safe protection, so the unit is intended for installation inside a suitable control cabinet rather than in an exposed machine location.

The electronics must operate inside 0–45 °C during normal use. Storage or shipment is permissible between -30 to +85 °C, which helps protect the unit from temperature-related stress while it is powered down. Full power is available up to 1000 m above sea level, so most industrial sites do not require altitude derating. The controller is Version 1, which identifies the product revision used for this unit.
