Product Description:

The DDS02.1-W025-R is a digital AC servo drive controller produced by Bosch Rexroth Indramat and placed within the DDS Drive Controllers series. The unit provides closed-loop control for matched Indramat servo motors in automated machinery, translating motion commands from a higher-level PLC into precise current and voltage for the motor windings. By combining power electronics with position and velocity feedback processing, the controller maintains stable shaft torque and speed in pick-and-place axes, packaging equipment, and material-handling stations. Its function is to regulate motor operation accurately during acceleration, deceleration, and steady-state movement so the connected axis follows the commanded motion profile.

The drive delivers a continuous output current of 25 A, which is the amount of motor phase current it can supply during normal operation without exceeding thermal limits. Heat generated by the power stage is removed through internal air cooling, so cabinet air moves across the heat sink instead of relying on an external blower. The enclosure has an IP20 rating that provides touch protection for live parts, so the controller is intended for installation inside a control cabinet. Position data is processed through resolver feedback, which provides rotor angle and speed signals that support stable torque control at low speed and at standstill. The permitted ambient temperature is 0 to 45 °C, so the controller should operate within that range for normal performance.

The controller can be mounted at elevations up to 1000 m above sea level without derating, which covers most factory installations. When de-energized, it can be stored or transported in temperatures from -30 to 85 °C. Within the product range, the unit belongs to line 02 and is released as version 1. These identifiers indicate the product generation used for this controller and help distinguish it from other versions in the same series.
