Product Description:

The DM 15K 7101-D is a servo drive module manufactured by Bosch Rexroth Indramat within the DM Servo Drives series. Installed between the machine control network and the motor power leads, it converts setpoint data into modulated phase currents that govern torque, speed, and position for industrial axes. In automation systems, the unit allows packaging machines, assembly robots, and conveyor systems to execute repeatable motion profiles while preserving the dynamic response expected from modern servo motors.

Control electronics inside the drive draw 0.89 A from the 24 V cabinet supply, so logic fuses and wiring can be sized accordingly. With a 4 kHz switching frequency, the continuous output is 11 Arms, and short-term events are supported up to 18 Arms. Raising the carrier to 8 kHz lowers the ratings to 7.4 Arms nominal and 15 Arms peak because the higher frequency increases transistor losses. The worst-case heat that must be removed is 121 W, and current capacity falls by 0.32 A per kelvin at 4 kHz or 0.23 A per kelvin at 8 kHz, so ambient temperatures directly limit continuous drive output. Motion commands are received through the CANrho setpoint interface, allowing integration with Indramat controllers.

The electronics have an IP20 protection class, which prevents accidental contact but relies on a closed cabinet for particulate shielding. A vertical outline of 445 mm by 50 mm conserves panel space, and the module weighs 6.0 kg, allowing straightforward handling during installation. Feedback channels support a single-turn resolution of 20 bits and a multi-turn depth of 32 bits, giving the controller fine position granularity over long linear or rotary movements. Compliance with shocks up to 15 g helps maintain calibration during transport, and the design also supports vibration encountered on moving machine frames.
