Product Description:

The DDS02.1-W150-DS01-02-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. As a digital servo drive, it provides the power and control link between an Indramat power supply module and a compatible synchronous or induction motor. In automated machinery and material-handling systems, it converts DC-bus power into regulated motor output so axes can follow commanded torque, speed, and position profiles. The controller is intended for multi-axis equipment where accurate motion is needed across conveyors, transfer units, and positioning assemblies.

Communication with higher-level CNC or PLC hardware is handled through a SERCOS interface, allowing cyclic command and diagnostic data to travel over a fiber-optic ring with other drives on the machine. Motor position data return through digital servo feedback, so the controller can close the motion loop internally and respond quickly to changing load conditions. Because the control loop closes in the drive, the host controller can issue motion commands without handling every encoder correction directly. The continuous armature current is rated at 150 A, which indicates the steady output the power stage can supply without thermal overload under normal operating conditions. Cooling is provided by internal cabinet air cooling, so the control cabinet must provide enough airflow to remove heat from the power electronics.

The unit belongs to Line 02, which places it in the corresponding DDS design line and keeps it consistent with related modules of the same line. It is Version 1, identifying the first revision of this controller. The controller carries Function ID 01, and its function set is fixed at the factory for this configuration. It is a digital AC servo drive controller with DC-bus coupling and a three-phase IGBT output stage rather than an analog amplifier circuit. This arrangement supports coordinated servo applications that require stable current control and integrated motion regulation.
