Product Description:

The DDS02.1-W015-RA01-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Positioned between the supply module and a servo motor, it converts command references into regulated three-phase currents that move and hold machine axes. By regulating current inside a control cabinet, the unit gives the connected motor stable response during acceleration, holding, and direction changes. This role suits repeatable torque and speed control in automated assembly, packaging, and material-handling equipment.

Command values reach the control electronics through an analog interface, so standard ±10 V PLC outputs can drive the velocity or torque loop without protocol converters. This arrangement is useful in systems that rely on conventional analog motion commands instead of network-based control. The power stage delivers up to 15 A of continuous motor current, which suits mid-range Indramat motors in cabinet-based installations. Rotor position arrives through resolver feedback, an electromechanical sensing method that preserves rotor angle information after power cycling. This feedback method supports reliable commutation and steady operation across changing load conditions. Heat from the IGBT stack is removed by air from inside the control cabinet, so the enclosure fan tray must maintain steady airflow across the heat sink. With a protection category of IP20, the housing is finger-safe but still requires installation inside a sealed control cabinet.

Continuous operation is permitted between 0 to 45 °C, and long-term storage is allowed from -30 to 85 °C without damage when the unit is not energized. Installation altitude may reach 1000 m before output or cooling must be derated because thinner air removes less heat. The drive is part of Line 02 in the DDS range, and it carries Function ID 01 with Version 1 for this control and power configuration. Storage at that range supports indoor spare inventory where seasonal temperature swings occur.
