Bosch Rexroth DDS02.1-W100-DA02-01 Digital Servo Drive

Product Description The DDS02.1-W100-DA02-01 is a high‑power modular digital AC servo drive from Bosch Rexroth (Indramat) DDS02.1 series (DIAX02 system). It features cabinet internal air cooling, 100 A continuous current, DA02 enhanced digital+analog feedback interface, and hardware version 01 (base firmware included). Designed for heavy‑duty dynamic motion control, it pairs with MDD/MKD synchronous motors and LAR/LAF linear motors, providing higher‑resolution analog emulation than DA01 models.

Core Functions

High‑current three‑loop control (current/speed/position) for heavy‑load dynamic response

DA02 interface provides enhanced encoder emulation (higher resolution, lower latency) compared to DA01, ideal for high‑precision analog system retrofits

Integrated firmware (version 01) enables out‑of‑the‑box commissioning without separate FW ordering

Compact internal cooling saves cabinet space; modular design supports flexible expansion

Full protection: overvoltage/undervoltage, overcurrent, short circuit, overheating, feedback loss

Supports torque/speed/position control modes for high‑power motion applications

Application Scenarios

Heavy‑duty CNC machine tools (milling/turning centers, grinding machines)

High‑power robotics and automated assembly lines

Packaging, printing, and textile machinery

Metalworking and material handling equipment

High‑precision multi‑axis retrofits requiring enhanced analog‑digital integration

Usage and Maintenance

Install vertically with adequate cabinet ventilation; avoid blocking airflow

Operate within 0–45 °C ambient temperature; derate at higher altitudes

Complete DC bus, control power, motor, and DA02 feedback wiring before commissioning

Configure parameters via IndraWorks; firmware pre‑integrated (no separate FW module needed)

Clean fan/heat sink every 6 months; inspect terminals and cables periodically

Calibrate control loops every 2 years to maintain stability
