Product Description:

The DDS02.2-A100-B is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. The unit interfaces between a machine's power distribution and its servo motors, converting DC link energy into precisely timed three-phase outputs while processing digital or resolver feedback to close the motion loop. It is used as the power stage and control interface for coordinated servo axes that must respond quickly to changing load conditions. This arrangement lets the drive regulate torque, speed, and position in automated assembly lines, packaging equipment, and machining centers.

Electrically, the controller delivers a continuous phase current of 100 A, which suits medium-to-high torque axes that require strong acceleration reserves. Its intermediate circuit operates at a nominal DC link of 300 V, and the power section tolerates fluctuations of ±15%, so normal plant supply variation does not interrupt stable motion. Thermal regulation uses air from outside the control cabinet, which helps keep warm enclosure air from circulating back through the power section. The housing has an IP20 rating, so the controller is intended for installation inside a closed cabinet while still allowing access to terminals and status indicators. These electrical characteristics support stable operation in systems that demand repeatable servo response over long production cycles.

The unit can deliver full current output at ambient temperatures up to +45 °C. Above that level, derating is required, although operation remains permissible up to +55 °C. Performance data apply at installation heights up to 1000 m above sea level, where reduced air density still provides sufficient cooling. Electronic assemblies tolerate non-condensing relative humidity up to 95 %, which suits humid production areas as long as moisture does not condense inside the cabinet. Separate storage limits and the auxiliary 24 V control supply are also part of the installation data for this drive.
