The documented DDS02.1-W200-D specifications give 200 A maximum/peak current and 65 A continuous output current, with a nominal 300 VDC DC bus and 24 VDC control supply. The “D” configuration is associated with digital servo feedback.
The DDS architecture is modular, so the exact drive assembly may contain additional interface or option modules. Communication and function identifiers should therefore be checked from the complete unit designation rather than assumed from DDS2.1-W200-D alone.
Product Introduction
The Bosch Rexroth Indramat DDS2.1-W200-D is a high-current digital servo control unit from the legacy DDS drive-controller family. It is intended for AC servo and main-drive applications where the controller receives digital motor-feedback information and regulates the associated drive system. The documd configuration is rated for up to 200 A peak current, with 65 A continuous output current.
This is not a standalone low-voltage servo amplifier with an independent AC input. The DD1- belongs to a modular drive architecture using a DC bus and separate control supply. Proper identification of the associated power supply, motor, feedback system, interface modules, and configuration is essential when replacing a field unit.

DDS2.1W200-D
Application Scenarios & Field Pitfalls
The D1- is most relevant to older machine-tool and industrial motion systems where the original Indramat DDS architecture remains in service.
Typical applications:
- CNC and machine-tool axes
- High-power AC servo motion systems
- Printing and converting machinery
- Textile machinery
- Packaging and production machinery
- Legacy multi-axis industrial automation equipment
Engineer’s checks before replacement:
- Confirm the exact type code.
DD1-and the commonly abbreviatedD1-refer to the same documented family designation, but additional suffixes can identify different configurations. Do not order from the shortened model alone when the original nameplate is available. - Check the DC-bus architecture. The documented unit uses a nominal 300 VDC bus with ±15% tolerance. It should not be treated like a modern standalone 230 VAC servo drive.
- Match motor feedback.e configuration uses digital servo feedback. The motor, feedback cable, feedback interface and drive configuration must be considered as one system.
- Verify continuous versus peak current requirements. The 200 A figure is not equivalent to 200 A continuous operation. Published technical data identifies approximately 65 A continuous output current and 200 A peak current. Thermal loading and machine duty cycle need to be checked accordingly.
- Do not assume modern communication protocols. Some secondary listings incorrectly attribute EtherCAT, PROFINET or other newer interfaces to this legacy DDS unit. Those claims should not be used for procurement without confirmation of the actual option module installed. The documented DDS configuration is modular and option-dependent.
- Back up machine parameters before replacement. Servo gains, motor data, feedback configuration, acceleration/deceleration limits and machine-specific drive parameters can be just as important as the hardware itself.

Procurement Note
For a replacement, specify 020-D together with the complete nameplate information, option cards, motor model, feedback type, associated power-supply module, machine/controller interface and firmware or parameter configuration.
One point deserves special attention: public listings contain technically incorrect descriptions of this model, including low-power 24–48 VDC servo-drive specifications and modern Ethernet-based interfaces. Those figures do not match the document1- configuration. For an actual replacement, use the original Rexroth/Indramat nameplate and complete type code as the final identification reference.
