Product Description:

The DDS02.1-W015-RA02-02-FW is a servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. In an automation cell, this unit forms the power and regulation stage between a supply module and a synchronous or induction motor. It converts DC bus energy into controlled three-phase output so axes can be positioned, synchronized, or indexed as required by a PLC or motion computer. This arrangement lets the controller regulate motor current in real time during coordinated machine motion.

The drive exchanges setpoints and diagnostics through an analog interface, which suits retrofits where digital fieldbuses are unnecessary. This channel also allows command values to be integrated with control hardware that uses conventional analog signaling. Its power section is rated for a continuous output of 15 A, a current level suitable for small- to medium-frame motors used on feeders, loaders, and auxiliary tables. Rotor position is returned to the drive by resolver feedback, and this sensing method tolerates shock and electrical noise while providing angle information for commutation. Thermal energy is removed by internal air cooling, so cabinet air passes through the heat sink without external ducts. The unit is identified as Line 02, placing it within the corresponding DDS design line.

The drive uses a separate firmware subitem, so the software package is selected to match the motor type and application requirements. Hardware detail is marked as Version 1, which corresponds to this component layout and connector pinout. Its classification as a digital AC servo drive controller allows speed, torque, and position control from the same platform. This makes the unit suitable for different axis duties without changing the basic controller type. The unit is intended for installation in the control cabinet, where enclosure airflow supports cooling and helps keep contaminants away from the electronics.
