Product Description:

The DDS02.1-W100-DS68-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. As a closed-loop drive unit, it supplies and regulates three-phase motors in automated machinery. It translates commands from higher-level motion controllers into precise torque and speed outputs. This allows the connected axis to respond accurately during positioning, feed, and speed-control tasks. Because regulation occurs inside the drive, motor current can be adjusted quickly as load conditions change.

Communication with the machine control network is handled through the SERCOS interface, enabling synchronous transfer of setpoints and diagnostic data on a single fiber-optic ring. Thermal management relies on internal air cooling, so the drive must be mounted where unrestricted cabinet airflow can pass through its heat sink. The unit is part of Line 02, which identifies the design line for this controller. It modulates the DC bus into three-phase output pulses for permanent-magnet or induction motors. The power stage is designed for continuous operation at 100 A of output current, allowing use with medium- to high-torque actuators without thermal derating during normal operation.

Axis accuracy is supported by the integrated digital servo feedback channel, which accepts high-resolution encoder signals and forwards position data to the drive's control ASIC for real-time current vector adjustment. This feedback path supports stable speed regulation and accurate rotor position tracking during continuous operation. The required software package is provided as a separate subitem, so the controller can be matched to the intended motion task instead of being locked to one fixed software set. The unit is Version 1. It also integrates with modular supply units used in the Indramat cabinet system, which helps maintain consistent electrical and mechanical fit within a DDS-based installation.
