Product Description:

The DDS2.1-W150-DA01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. This unit converts regulated DC energy from a shared supply rail into controlled three-phase output for servo motors, allowing precise speed and torque regulation in automated machinery. By integrating with a central supply and motion bus, it acts as the link between CNC or PLC commands and electromechanical movement in packaging lines, printing equipment, and assembly stations.

The drive’s power section is rated for continuous operation at 80 A and can accept transient demands up to 150 A. These current ratings indicate the motor load the unit can support without thermal derating. Energy is drawn from a DC link held at 300 VDC ±15%, and the controller requires external DC bus rails to share this voltage with other axes. Brake release circuitry is powered from a dedicated 24 VDC ±10% line, which keeps that function separate from the main converter supply. Control electronics inside the basic unit draw 500 mA from the machine’s +24 V utility supply, and a 1.5 W start-lockout coil helps prevent unintended energization. Parameterization and diagnostics are performed through the V24, RS 232C service interface, enabling local access without proprietary adapters.

Installation is permitted in cabinets where the ambient temperature remains between 0 – 45 °C, and the unit can be stored or transported at temperatures from -30 – 85 °C. The protection category of IP20 means the drive needs enclosure protection against dust and fluids during operation. Acceptable mounting altitude extends to 1000 m, and operation is permissible at up to 95% relative humidity with absolute moisture limited to 25 g/m³. The drive also supports a continuous current capability of 65 A at the maximum permissible peak setting without exceeding thermal limits.
