Product Description:

The DDS03.1-W030-RL20-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in a control cabinet, it modulates stator current for matched Rexroth motors and converts motion commands from CNCs or PLCs into controlled switching sequences for industrial motion. This allows the drive to manage acceleration, deceleration, and steady-state speed in packaging machines, pick-and-place gantries, and other automated systems that require repeatable axis movement. The unit is part of Line 03 and uses Version 1.

During operation, the controller can deliver up to 30 A of continuous output current, so the connected motor must be matched to that current level. The housing has an IP20 rating, which means the drive is intended for installation inside a protective enclosure when dust or moisture is present. Heat is removed by internal air cooling, so the thermal condition inside the cabinet directly affects drive performance during continuous duty. The permissible ambient range is 0 to 45 °C, which fits typical factory environments when cabinet ventilation is adequate. The control mode supports single-axis position control, allowing the drive to regulate one mechanical axis directly without requiring an external axis card.

For non-operating periods, the electronics tolerate storage temperatures from -30 to 85 °C, which supports transport and warehousing across a broad range of conditions. Installation height is limited to 1000 m because reduced air density above that level lowers cooling effectiveness. Precise rotor angle data is processed through resolver feedback, so the drive can evaluate motor position and speed without a separate encoder converter. This feedback method also supports stable closed-loop operation in industrial environments where electrical noise can affect signal quality.
