Product Description:

The DDS02.1-W050-RA02-01 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As a digital AC servo drive controller, it coordinates power delivery and motion commands between an Indramat supply module and a compatible synchronous or asynchronous servo motor on automated axes. Within an automation cell, the unit converts commands from higher-level control hardware into regulated three-phase output for precise velocity, position, and torque control. This arrangement lets the controller serve as the regulation stage for stand-alone machine axes as well as coordinated multi-axis systems.

Electrical capacity is provided by a continuous output of 50 A, which is the maximum motor phase current the drive can supply without derating. Command data reach the power section through an analog interface, so speed or torque references are transmitted as standard voltage or current signals instead of a fieldbus stream. This setup fits control systems that use conventional reference wiring and separate signal channels. Thermal management relies on internal air cooling, meaning cabinet air moves across the heat sinks to remove semiconductor losses without an external blower. Protection is limited to IP20, so the unit requires installation inside an enclosure. For position feedback, the controller is matched to motors that use resolver feedback, which maintains reliable shaft-angle signals under shock and temperature variation.

The drive can operate at rated load in ambient temperatures from 0 to 45 °C. When powered down, storage is permitted from -30 to +85 °C if condensation is avoided. Installation altitude is limited to 1000 m above sea level so cooling and insulation performance remain within the intended range. The unit is Version 1, and it uses Line 02 with Function ID 01. These identifiers distinguish the product generation and control configuration within the DDS platform.
