Product Description:

The DDS02.2-W050-BE84-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates three-phase servo motors by generating pulse-width-modulated output and processing high-speed feedback signals. Installed next to a supply module on a shared DC bus, the unit distributes regulated power so that positioning tables, gantry axes, and packaging stations achieve deterministic motion cycles in industrial automation. This arrangement helps the controller maintain stable torque and speed response as load conditions change during operation.

Communication with the master controller occurs over the SERCOS interface, a fiber-optic network that delivers cyclic setpoints and status data with low jitter. The power stage is dimensioned for a continuous output of 50 A, allowing the drive to energize medium-inertia motors without thermal derating during rapid acceleration profiles. Thermal management is handled by internal air cooling, so cabinet air moves through the heat sink without the need for an external blower. Precise position information is accepted through digital servo feedback, which works with Indramat encoders to close the velocity and position loops at high resolution. The unit is part of Line 02, which matches the connector arrangement used with second-generation power supplies.

The optional secondary encoder channel accommodates resolver feedback, which is often used in high-temperature areas or in systems that do not require absolute position memory. The controller is Version 2, which supports shorter interpolation cycles and expanded error diagnostics. It carries Function ID Version 01, which keeps the parameter set aligned with this control variant. The operating code is supplied as a separate subitem, so the controller can be matched to the required axis functions without including unused software modules.
