DM 45K 6111-D

The Bosch Rexroth Indramat DM 45K 6111-D from the DM Servo Drives series is engineered for robust motion control with a 670 V input voltage and a high-speed PROFIBUS-DP interface. Featuring a Standard encoder interface, this drive supports precise position feedback for industrial automation. Its natural air cooling system dissipates heat efficiently without auxiliary fans, while the compact form factor maintains a net weight of 6.7 kg for simplified cabinet integration. With a modular design, it accommodates both supply and axis modules to match diverse application requirements.

The Servodyn-D inverter system employs digital control loops for current, speed, and position, and offers two selectable switching frequencies of 4 kHz and 8 kHz. At 4 kHz, the drive delivers a rated current of 23.5 A_rms with a peak current of 35.5 A_rms at 45 °C ambient temperature. The 8 kHz configuration provides a rated current of 16.5 A_rms and a maximum current of 25.5 A_rms under the same thermal conditions. Temperature derating is managed at 0.6 A/K above +45 °C for the 4 kHz model and 0.5 A/K for the 8 kHz variant, ensuring reliable performance up to +55 °C.

Safety and serviceability are paramount: the drive’s IP20 protection class requires installation within IP54-rated switch cabinets for dust and splash resistance. The design limits maximum power loss to 205 W, reducing thermal stress on surrounding components. A standardized encoder interface facilitates one-axis positioning, and a global one-year warranty from Wake Industrial offers peace of mind for maintenance and support.
