Product Description:

The DDS02.1-W015-DS01-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Classified under line 02 and delivered in hardware version 1, the module fits into multi-axis power racks where several drives share a common DC bus. Its role in industrial automation is to translate motion commands from a host controller into precise voltage and current patterns for a connected motor. In coordinated machinery, it helps maintain stable speed and position control throughout the machine cycle, especially where several axes must respond predictably to centralized control.

Communication with higher-level PLCs is established through the SERCOS interface, providing deterministic fiber-optic data exchange for synchronized axes. The drive supplies a rated continuous output of 15 A, which is the available phase current during continuous operation without thermal derating. Heat is removed by air drawn from inside the control cabinet, so the enclosure must provide enough internal airflow for steady operation. Rotor position is returned to the control loop by digital servo feedback, allowing high-resolution interpolation at the drive level. The housing has an IP20 rating, so the unit must be installed in a closed electrical cabinet away from liquid spray and fine dust. Because the cooling air is taken from the cabinet interior, the thermal condition of nearby components can influence drive temperature during extended duty.

The permissible ambient range for active service is 0 – 45 °C, while transit or warehouse storage can occur between -30 – 85 °C without damage to electronic components. Reliable operation is specified up to 1000 m above sea level; installations at greater heights require output derating because thinner air reduces cooling effectiveness. The unit carries function code 01, which sets the fixed operating profile for this drive type. Ambient temperature, altitude, and cabinet ventilation should all be considered when the drive is integrated into sealed enclosures or other space-constrained control assemblies.
