Product Description:

The DDS02.1-A150-DS46-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. The unit belongs to Line 02 and is Version 1 within that design line. Installed in multi-axis machines, it provides precise current and speed regulation for AC servo motors and forms the power conversion stage between the control system and the motor. Because it handles regulated motor power directly, it helps motion axes respond accurately during positioning, speed changes, and coordinated machine movement.

Command and feedback data are exchanged over the SERCOS interface, which uses fiber-optic communication for fast cyclic synchronization between the master and the drive. Thermal management is handled by external air cooling, so cabinet design must allow outside airflow to pass across the heat sink instead of recirculating warm internal air. This cooling method helps remove heat from the power section during continuous operation. The power section can deliver up to 150 A of continuous output, supporting servo axes that require sustained torque. The unit has an IP20 protection category, so it is intended for clean enclosed panels rather than exposed machine locations. Reliable operation is supported in ambient temperatures from 0 to 45 °C, which suits typical indoor industrial environments.

Motor position is returned through digital servo feedback, allowing high-resolution closed-loop control for accurate speed and position regulation. When the machine is idle or stored, the electronics can tolerate temperatures from -30 to 85 °C, which helps protect the unit during transport and warehouse storage. Installation sites up to 1000 m above sea level are supported without reconfiguration, making the controller suitable for most standard facilities. The drive requires firmware ordered separately so the software can be matched to the intended motor and control application.
