Product Description:

The DDS02.1-W025-DS04-01 is a Digital AC Servo Drive Controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It governs three-phase servo motors in automated machinery by converting command data into precisely timed current and voltage patterns that match the connected motor. Inside an automation cell, the unit operates as the drive-axis node, linking the higher-level PLC to the motor and closing torque and velocity loops required for accurate positioning.

Communication with the motion controller is handled over the SERCOS interface, a deterministic fiber-optic bus that transports real-time setpoints and diagnostics. Thermal management depends on air drawn from inside the control cabinet, so the device must be installed where internal airflow is unobstructed. The power stage delivers a continuous phase current of 25 A, giving adequate headroom for medium-torque servomotors while staying within semiconductor limits. The enclosure has an IP20 rating, which allows finger-safe access but does not provide liquid sealing, making it suitable for cabinet installation. Operation is permitted up to a maximum elevation of 1000 m; above this height, derating is required because reduced air density lowers cooling effectiveness and insulation strength.

Motor position data is returned through digital servo feedback, allowing the control loops described earlier to close with high resolution and low latency. For preassembled panels that may face storage or transit extremes, the unit withstands temperatures from -30 to 85 °C without loss of function once powered under normal operating conditions. The unit carries Function ID version 01 and belongs to line 02. Continuous duty is permitted in ambient temperatures from 0 to 45 °C, provided internal cabinet ventilation remains within the stated limits.
