Product Description:
The DDS2.1-W025-DS03-01 belongs to the Bosch Rexroth Indramat DDS Drive Controllers series. Designed for multi-axis automation, this servo drive receives motion commands, modulates current, and monitors feedback to keep synchronous or induction motors on target for position and speed. It operates as the power and control stage in a multi-axis system, converting bus energy into regulated motor current for coordinated motion. By integrating power conversion, signal processing, and network communication in a compact frame, the unit helps conserve cabinet space in packaging machines, material handlers, and machining centers.
It exchanges real-time setpoints over the SERCOS interface, while a backplane link supplies the controller with a 300 VDC bus voltage. This arrangement allows the drive to work with centralized motion control while sharing power with adjacent axes. Digital servo feedback arriving on the X2 15-pin D-Sub supports closed-loop accuracy for speed and position control. The drive can deliver up to 25 A of motor phase current. Heat is removed by internal air cooling, and the housing has an IP20 rating that helps protect against accidental contact with internal parts. A V24, RS232C port is provided for service access and serial data exchange.
Ambient operation is allowed from 0 to 45 °C, with installation elevations up to 1000 m above sea level. The enclosure stands 390 mm high and weighs 7.5 kg, so adequate spacing and support are required inside the cabinet. Proper fastening requires 5 Nm of mounting torque, and incoming power lugs are tightened to 3 Nm. Control safety includes a lockout circuit that consumes 1.5 W and switches contacts rated 24 VDC at 1 A. Brake solenoids receive release power from 24 VDC for connected motor brakes. Storage is permitted from -30 °C to 85 °C when the unit is inactive, which supports transport and warehousing before installation.
