Product Description:

The DDS02.1-A200-DS03-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. In automated machinery, the unit modulates three-phase power so that synchronous and induction servomotors follow precise torque and velocity commands from a motion control system. It serves as the power stage for closed-loop motion tasks that require accurate acceleration, stable speed regulation, and repeatable axis behavior. The controller also helps reduce panel space and supports coordinated operation in multi-axis systems used in pick-and-place gantries, packaging lines, and machining centers.

For networked drives, the controller communicates via the SERCOS interface, a fiber-optic ring that supports cyclical telegram timing and error detection across multiple axes. The power section is sized for a continuous output of 200 A, enabling it to energize high-torque motors without derating under normal operating conditions. The enclosure has an IP20 rating, so the unit is intended for installation inside an electrical cabinet. Thermal management relies on external air from outside the control cabinet, and fresh air is drawn through the heat sink so internal cabinet temperature is not elevated. Reliable operation is permitted in ambient temperatures from 0 to 45 °C. This operating range suits most enclosed industrial installations when airflow to the heat sink remains unobstructed.

Position loop resolution is maintained through digital servo feedback, allowing the drive to process encoder data directly and close velocity loops without additional hardware. This feedback method helps the controller respond quickly to changing load conditions during positioning and speed control. Mounting is permitted up to 1000 m above sea level, which supports rated insulation spacing and cooling performance at typical plant elevations. Storage and non-operating conditions are covered by a range of -30 to 85 °C, helping protect the unit during shipment or warehousing. The unit is part of line 02, and the design is classified as version 1.
