Product Description:

The DDS02.1-W025-DA14-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. In an automation cell, it links the higher-level control system with a servo or induction motor, regulating phase current and processing feedback so the axis follows programmed motion profiles during acceleration, constant-speed travel, and stopping. When mounted inside a protected cabinet, the unit works with compatible power supplies and motors to form a modular drive package for material handling, printing, and packaging equipment. This arrangement lets the controller serve as the power and regulation stage within a coordinated motion system.

This controller delivers a continuous output of 25 A, so its power stage can supply that current to the motor windings without thermal derating during rated operation. Command and diagnostic data enter through an analog interface, allowing simple ±10 V speed or torque references from legacy PLC hardware. This makes the unit suitable for motion systems that rely on straightforward hardwired control signals. Its housing carries an IP20 rating, so fingers and tools are guarded, but the installation site must remain free of airborne moisture or conductive dust. The controller is intended for ambient air temperatures of 0–45 °C; outside this range, component life and measurement accuracy decline. Position reporting relies on digital servo feedback, which transfers high-resolution encoder data to the controller for tight speed loops and fault detection.

The maximum installation altitude is 1000 m; above this height, reduced air density limits heat dissipation and the current rating must be lowered. Heat is removed by internal air cooling, which draws cabinet air across the heat sink, so the cabinet layout must provide unobstructed airflow. When the machine is stored or shipped, the drive withstands temperatures from -30 to 85 °C without damage to capacitors or solder joints. The unit requires a separate firmware order. It is part of Line 02 and uses Function ID Version 01 with hardware Version 1.
