Product Description:

The DDS02.1-W025-RA02-00 is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. It commands three-phase servo motors in industrial automation cells by modulating voltage and current according to reference signals from a PLC or motion card. Acting between motor feedback and higher-level sequencing, the unit supplies regulated power, monitors axis conditions, and exchanges status data during packaging, material-handling, and machining tasks. It is suited to axis modules that rely on dedicated drive hardware rather than separate external amplifiers, which helps keep motion control functions concentrated in one cabinet location.

This controller delivers a continuous output of 25 A, so it can supply that phase current during normal duty cycles without derating. Command signals enter through an analog interface, which allows velocity or torque setpoints to be sent as voltage or current levels instead of network telegrams. Heat is removed by internal air cooling, so cabinet air must move across the heat sink to keep the power section within its intended operating range. The IP20 enclosure is intended for protected control cabinets, where contact with conductive dust or liquids is avoided. Position and speed are closed through resolver feedback, which gives the drive a stable motor angle signal for commutation and closed-loop regulation.

The drive belongs to Line 02 and is supplied as Version 1, placing it within an established DDS product generation. It can be mounted up to 1000 m above sea level without output reduction, which suits most standard factory installations. Reliable operation is specified at ambient temperatures from 0 to 45 °C, while storage is permitted between -30 and 85 °C when the unit is not in use. The stated storage range helps protect electronic components during warehousing and shipment before installation.
