Product Description:

The DDS02.1-A200-DS04-01 is a digital AC drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Installed between the power supply and a compatible Indramat servo motor, it modulates three-phase output to generate commanded torque and speed profiles. The device serves as the axis module in modular automation racks, allowing synchronized positioning, dispensing, or machining processes that depend on deterministic current regulation. This arrangement lets a central control system coordinate multiple motion axes while the drive handles the fast electrical response required at the motor. It is intended for multi-axis equipment where repeatable motion and compact cabinet integration are both required.

For networked control, the unit communicates through the SERCOS interface, a fiber-optic bus that carries cyclic setpoints and diagnostic data for synchronized motion control. The fiber-optic connection also helps isolate the command channel from electrical noise inside the cabinet. At the power stage, it can deliver up to 200 A of continuous output current, so it can drive large-frame synchronous motors without derating. Electrical parts are protected to IP20, which means the controller must be mounted inside a closed cabinet. Thermal energy is removed by external air cooling, with cooling air passing across the heat sink to keep semiconductor temperatures within limits. The electronics remain fully functional across an ambient range of 0–45 °C, permitting installation beside other heat-generating modules in a properly ventilated enclosure.

Rotor position is reported over digital servo feedback, letting the controller regulate current, speed, and position with precise motor feedback. This feedback format supports closed-loop operation with compatible servo motors. Rated performance is maintained up to 1000 m installation height, so standard drive data apply at typical factory elevations. When the unit is not in operation, it can be stored between -30 to +85 °C without damage to passive or active components, which supports unpowered storage and transport. The controller is supplied in Version 1 and uses Function ID 01 for this configuration.
