Product Description:
Bosch Rexroth Indramat manufactures the DM 8K 1301-D as part of the DM Servo Drives series. The module converts a common DC bus into three-phase motor power while exchanging motion commands over a fieldbus. In automated gantries, packaging lines, and assembly stations, it forms the closed-loop interface between a SERCOS motion controller and the motor resolver. This allows the axis to maintain commanded speed and position with high repeatability during synchronized motion. Its design is intended for cabinet installation, where forced air cooling helps keep internal temperature within the permitted range.
The 24 V control rail draws 0.89 A, supplying logic circuits and enabling functions during main-bus shutdowns. The DC link accepts regulated 670 VDC and continues up to 715 VDC when the supply is unregulated, providing headroom for regenerative peaks. With a carrier frequency of 4 kHz, the open-loop stage can deliver a peak motor current of 10 Arms for acceleration events, while the closed-loop limit is 5.7 Arms for continuous duty. This separation between peak and continuous current supports short acceleration demands without exceeding steady-state thermal limits. Thermal loading during operation produces a maximum power dissipation of 96.5 W, which is removed by the built-in air cooling fan. Incremental encoder feedback is processed up to 1 MHz, and resolver signals are decoded at 12-bit resolution to support accurate position control. Sine and cosine encoder channels are accepted up to 800 kHz and 50 kHz respectively.
The housing width is 50 mm, which helps with side-by-side cabinet mounting, and the drive weighs 6.0 kg. The narrow housing is useful where several axes must be mounted in the same enclosure with limited lateral space. Position data are buffered internally with a multi-turn resolution of 32 bits, while single-turn detail reaches 20 bits for fine interpolation across long strokes. Command values arrive through the SERCOS setpoint interface, and resolver-based commutation supports stable axis control across the available feedback ranges.
