Product Description:

The DDS02.1-W150-DS04-03-FW is a servo drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. As a closed-loop amplifier, it regulates the current, torque, and speed of connected servo motors so they can carry out precise positioning tasks in automated machinery and material-handling cells. The unit is installed in a control cabinet and works with modular supply units to form multi-axis drive stacks. This arrangement is commonly used in packaging lines, robotics, and printing equipment where coordinated motion is required across several axes.

Communication with a higher-level PLC takes place through the SERCOS interface, allowing deterministic fiber-optic command and feedback cycles. The unit uses internal air cooling, so enclosure air passes across the heat sink without the need for external ducting. A continuous output of 150 A is the rated motor phase current the drive can deliver without derating, which makes it suitable for direct control of large-torque servomotors. Position data from the motor returns through digital servo feedback, allowing the controller to maintain accurate closed-loop regulation during motion. The drive is part of line 02, which identifies its design line within the series.

The unit is a Digital AC Servo Drive Controller, so operating parameters are stored electronically rather than by fixed hardware settings. It carries Version 1, which means its diagnostics and parameter structure follow the first release of this platform. Application-specific functions are provided through a separate software package that is inserted into the front loading slot. This layout keeps the power section and the application layer organized within the same chassis while allowing the drive to be adapted for different control tasks.
