Product Description:

The DDS02.1-W100-RA02-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and included in the DDS Drive Controllers series. In automated machinery, this unit provides closed-loop speed and torque regulation for synchronous and induction servomotors, acting as the intermediate power stage between the motion controller and the motor windings. By regulating current in response to command signals and motor feedback, it helps the axis maintain stable motion under changing load conditions. It is suited for multi-axis equipment such as packaging lines, printing presses, and material-handling gantries where coordinated motion is required.

This controller exchanges setpoints and feedback through an integrated analog interface, a format commonly used when the host CNC or PLC provides ±10 V velocity or torque commands. This approach supports integration with motion systems that use traditional analog reference channels instead of digital fieldbus communication. Cooling is handled by air from inside the control cabinet, so steady cabinet airflow must remove switching losses from the heat sink. Rotor position is monitored by resolver feedback, enabling sinusoidal commutation without relying on a digital encoder. The power section is rated for a continuous motor current of 100 A, allowing sustained torque output without exceeding thermal limits. All live parts sit behind an IP20 barrier, which provides finger protection in enclosed panel spaces and requires the cabinet to provide broader enclosure protection.

Proper ambient control keeps the drive within its functional envelope of 0 to 45 °C during operation and -30 to 85 °C during storage. The storage range applies when the unit is not energized and helps protect insulation materials and internal components. Installations are permitted up to 1000 m above sea level, and higher elevations require current derating because lower air density reduces cooling effectiveness. The unit belongs to Line 02 and build Version 1. These identifiers distinguish the product generation used for this drive type.
