Product Description:

The DDS02.1-W150-RL01-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts motion commands from a PLC or CNC into regulated current and voltage for one motor, supporting controlled speed and position in packaging, printing, and material-handling equipment. By combining power electronics, resolver processing, and protective monitoring in one rack-mounted unit, the controller reduces external module count and keeps cabinet layouts compact. The drive is intended for installations that need a dedicated axis controller rather than a shared multi-motor power stage. Its closed-loop design helps maintain accurate motion during changing load conditions and repeated start-stop cycles.

The control interface supports single-axis position control, so one drive channel is assigned to one mechanical axis. Cooling is provided by internal air cooling, and the air inside the control cabinet must remain between 0 to 45 °C for normal operation. The power stage can supply up to 150 A of output current, which suits demanding acceleration and deceleration cycles on high-inertia loads. The enclosure has an IP20 rating, which helps protect against accidental finger contact but does not protect against water. Resolver feedback from the connected motor is used to close the speed and position loop, including at very low speed. Because cooling air comes from within the cabinet, the panel layout must allow steady internal airflow around heat-producing components.

The drive carries Function ID 01 and belongs to Line 02, and the platform version is 1. Maximum installation altitude is 1000 m, and output current must be reduced above that height because thinner air lowers cooling performance. When the unit is powered down, it can be stored within a temperature range of -30 to 85 °C without harming the electronics. These limits apply when the drive is installed in elevated facilities or kept in unpowered storage between periods of use.
