Product Description:

The DDS02.1-W100-D is a servo drive controller produced by Bosch Rexroth Indramat for installations that use the DDS Drive Controllers series as the motion interface between power supplies and Indramat synchronous motors. Mounted inside a machine control cabinet, it converts reference commands from a PLC into timed three-phase output patterns that regulate torque, speed, and position. The module combines power electronics, signal processing, and fieldbus connectivity in one housing, which helps reduce cabinet complexity in packaging, printing, and material-handling equipment. This arrangement lets the drive respond quickly to setpoint changes while supporting coordinated axis motion during normal machine operation.

For its internal electronics, the controller draws 150 mA (-15 V) and 150 mA (+15 V), plus 500 mA on the +24 V service rail. These limited demands reduce the load on auxiliary supplies and help limit heat buildup inside the enclosure. Thermal management uses internal cabinet air cooling, so the device depends on airflow already present around adjacent modules rather than an external blower. During accelerations or abrupt command changes, it can deliver 100 A of peak phase current to the motor, providing short-term torque reserve for high-inertia loads.

Closed-loop regulation is achieved with digital servo feedback, allowing the drive to evaluate position data directly over a synchronous serial channel. As a Digital AC Servo Drive Controller, the unit uses oversampling current loops and programmable acceleration limits that suit Line 02 hardware. The unit is Version 1, which aligns parameter maps with the first-generation DDS tool set. Under steady load, it also supports continuous phase current for sustained output on demanding axes, provided cabinet airflow is sufficient for normal heat removal.
