DM 8K 1301-D

The Bosch Rexroth Indramat DM 8K 1301-D from the DM Servo Drives series is a high-performance module engineered to deliver precise position, speed, and current control. This three-phase system operates on a regulated DC link voltage of 670 VDC or a non-regulated 715 VDC, drawing power from a 670 V supply via a native SERCOS interface. It employs a robust Resolver encoder as its direct position measuring system and supports sine/cosine encoders up to an 800 kHz frequency limit. Designed as part of the Servodyn-D family, the DM 8K 1301-D integrates seamlessly with backplane modules and inverters in compact automation architectures.

Performance at the DM 8K 1301-D’s core is defined by an optimized switching frequency of 4 kHz (f_s), allowing rapid current adjustments. The unit delivers a peak overload current of 10 A and sustains a continuous overload current of 9.6 A, while its nominal rated currents reach 2.1 A (peak) and 5.6 A (continuous). Thermal resilience ensures no current derating up to 45 °C, with a controlled derating slope of 0.1 A/K between 45 °C and 55 °C ambient. Pre-set parameters and comprehensive drive-data simplify commissioning, and inherent performance stability keeps the module’s operational characteristics virtually unaffected by typical factory environment variations.

Weighing just 6 kg and occupying a 50 mm panel width, the DM 8K 1301-D achieves an exceptional power-density ratio for its class. Its compact dimensions and modular design facilitate high-density cabinet layouts and streamlined service access. As a fully integrated subsystem within Bosch Rexroth’s Servodyn-D inverter ecosystem, this drive delivers reliable, precision control for demanding automation applications in packaging, material handling, and machine tool industries.
