Product Description:

The DDS02.1-W050-DA11-01-FW belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As a closed-loop axis module, it conditions three-phase power and processes command signals so an automation system can adjust torque, velocity, or position on connected AC servomotors. Installed inside a motion cabinet, the device forms the link between the machine PLC and the motor, supplying regulated current while exchanging diagnostic data during operation. Because it works between the control system and the motor, the unit supports coordinated axis motion in automated production equipment.

This controller communicates with the higher-level control system through an analog interface, so setpoint voltages and actual-value feedback are transferred as ±10 V signals rather than fieldbus frames. During operation, it can deliver a continuous phase current of 50 A, giving it the capacity to run medium-frame Indramat motors without derating. Heat is removed by internal air cooling, so the surrounding enclosure must maintain adequate airflow. The housing carries a protection rating of IP20, which limits installation to dry, dust-controlled electrical rooms. Rotor position is resolved by digital servo feedback, allowing the unit’s microprocessor to calculate precise commutation angles. The drive is part of Line 02 and uses Function ID 01 with Version 1.

The thermal envelope of the drive spans ambient temperatures from 0 to 45 °C, so no output reduction is required within the normal operating range. It can be stored or transported between -30 to 85 °C without damage to internal components. Altitude capability reaches 1000 m above sea level, and operation above that height may require additional cooling review. The stated storage range also allows the unit to remain in unpowered transit or warehouse conditions without special thermal protection. These ranges cover normal cabinet operation, transport, and storage in controlled indoor industrial environments.
