Product Description:

The DDS02.1-W015-RA11-00 is a drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Deployed inside multi-axis cabinets, it supplies regulated three-phase power to servomotors so automated machinery can follow precise torque, speed, or position commands from higher-level motion processors. The model follows the modular DDS platform, letting each axis use a suitable current rating and feedback type while keeping a shared DC bus and an identical mechanical footprint. Because the housing uses the same overall form factor as related DDS modules, the controller can be arranged beside other axes in the same cabinet row without changing rack spacing.

The drive has a rated current of 15 A, which is the continuous phase current the power stage can deliver without derating. Command and diagnostic data reach the drive through an analog interface, allowing ±10 V velocity or torque references from legacy PLCs. That input method fits control systems that do not use a serial motion bus. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink instead of an external blower. Rotor position is evaluated through resolver feedback, which the controller reads with a transformer-based circuit for commutation and speed regulation. The unit is a Digital AC Servo Drive Controller, so current regulation and fault logic are executed digitally. By combining analog command input with resolver evaluation, the controller supports servo systems that use traditional feedback hardware rather than digital networked encoders.

This unit is part of the 02 line, so its dimensions match other second-generation frames with common bus bars and shared I/O pinouts. It is listed as version 1, indicating the first release for this current class and feedback option. The common mechanical format helps the unit fit mixed-axis racks that use the same module spacing and connector positions. This also helps maintain a consistent panel layout when one machine includes several drives with different current ratings or motor feedback arrangements.
