Product Description:

The DDS02.1-W100-DS51-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates torque, velocity, and position for synchronous or induction servomotors in automated machinery. By converting commanded setpoints from a motion control system into precise three-phase output, the unit acts as the link between higher-level PLC logic and the mechanical axis. This arrangement supports coordinated motion in packaging, material handling, and machining equipment where repeatable acceleration, braking, and positioning are required. The controller is suited to multi-axis systems that need stable closed-loop performance without a separate motion interface at each motor.

Communication with a master drive or PLC is handled through the SERCOS interface, which provides deterministic fiber-optic data exchange for real-time control updates. Fiber-optic communication also helps reduce susceptibility to electrical noise from nearby power wiring. Continuous output is supported by a rated current of 100 A, so the drive can be matched with medium- to high-power motors without parallel amplifiers. Thermal management uses internal cabinet air cooling, so the enclosure must provide enough airflow to carry away switching losses. The front housing has an IP20 rating for finger-safe access and is intended for installation inside a control cabinet rather than in open machine areas. Reliable operation is allowed at ambient temperatures from 0 to 45 °C, which suits normal industrial indoor environments.

Functional altitude is limited to 1000 m above sea level, and operation above that height requires derating. When the equipment is not in use, it can be stored from -30 to 85 °C without harming the electronic components. Motor position feedback is processed as digital servo feedback, allowing closed-loop commutation and accurate speed and position control during changing loads. This feedback method also supports consistent motor response at low speed and during positioning moves. The controller belongs to Line 02 and is Version 1.
