Product Description:

The DM 15K 9101-D servo drive is built by Bosch Rexroth Indramat and belongs to the DM Servo Drives series. As a compact current and velocity regulator, it supplies controlled power to synchronous or asynchronous motors so that automated lines, packaging systems, or material-handling axes follow commanded profiles with repeatable accuracy. The unit accepts motion setpoints from upper-level controllers and converts them into precise motor currents, integrating seamlessly into distributed machine architectures.

The drive uses an IGBT stage that switches at 8 kHz and modulates the DC link into sinusoidal phase currents. Under 4 kHz carrier operation, it provides a continuous output of 11 Arms. For short overloads, it delivers up to 18 Arms while protecting itself with thermal monitoring and derating logic. Convection removes heat because the power section is air-cooled; this method simplifies cabinet design but requires unobstructed airflow. The housing carries a protection rating of IP20, so installation must be inside an electrical enclosure free from conductive dust. Feedback can be processed through STG or MTG interfaces, and an internal resolver channel supports 12-bit position capture, allowing the controller to close high-resolution loops without external converters.

Only 0.89 A is drawn from the 24 V control supply, leaving ample margin for auxiliary logic rails in multi-axis racks. During maximum thermal load, the inverter dissipates 121 W, a value that helps determine cabinet ventilation needs. With a module height of 430 mm and a compact mechanical design, the unit saves panel space while still providing 32-bit MTG and 20-bit STG feedback resolution for fine interpolation. Motion commands reach the drive through the CANopen and CANrho setpoint interface, keeping wiring minimal and enabling synchronized, deterministic communication across the machine network.
