Product Description:

The Bosch Rexroth Indramat DM 15K 1101-D belongs to the DM Servo Drives series and functions as a compact single-axis drive controller for synchronous and asynchronous servo motors in factory automation. Inside a coordinated multi-drive system, it converts a stabilized DC bus into controlled three-phase output, allowing precise velocity and torque regulation for machine tools, packaging lines, and material-handling stages. The module is engineered for direct integration with SERCOS motion networks, giving PLCs deterministic command of motor position and speed while maintaining feedback integrity through its standard encoder channel.

Electrically, the drive operates from a DC link of 670 VDC and generates motor phase currents through an internal IGBT bridge that switches at a default carrier frequency of 8 kHz. Under continuous duty, the module supplies a phase current of 7.4 A rms, while short-term overload events can be handled up to 15 A rms. If the cabinet temperature rises above its reference point, the output is reduced by 0.23 A for every kelvin according to the stated current derating. Logic and control electronics draw 0.89 A from the auxiliary 24 V supply. All terminations are enclosed within an IP20 housing that is intended for protected cabinet mounting and helps prevent direct finger contact with live parts.

The remaining operating envelope is set by the unit’s thermal and mechanical limits. The design dissipates a maximum of 121 W as heat, so enclosure airflow must remove this loss to maintain rated current. With a module width of 50 mm and a mass of 6.0 kg, multiple units can be installed side by side on a cold plate without excessive weight loading. The unit withstands shocks up to 15 g and is validated for vibration and temperature changes within climatic category 3K3. Correct performance is maintained up to 1000 m installation altitude, with current capacity decreasing above this height.
