DM 45K 4101-D

The Bosch Rexroth Indramat DM 45K 4101-D drive from the DM Servo Drives series delivers a robust Input Voltage of 670 V and features an Analog, 16 bit resolution interface for precise control. This Servodyn-D module is equipped with a Standard encoder interface and operates using a VeCon chip-based cascade for position, speed, and current control. Housed in a 75 mm width profile weighing 6.7 kg, the compact three-phase module integrates seamlessly into industrial switchgear. Its fully digital controllers provide consistent performance across demanding motion profiles.

Featuring selectable Switching Frequencies of 4 kHz and 8 kHz, the DM 45K 4101-D supports a Rated Current of 35.5/25.5 A₍rms₎ and a Maximum Current of 23.5/16.5 A₍rms₎, ensuring ample drive capability for SF, SR, DU, and synchronous linear motors. The device rectifies a 3×400–460 V AC supply into a regulated DC link voltage of 670 VDC (regulated)/715 VDC (non-regulated) via its 24 V auxiliary supply. Hysteresis-free operation is maintained by a 16-bit analog interface coupled with the DSS-D commissioning and service system, streamlining parameter adjustments and firmware updates.

Engineered for a permissible ambient temperature range of 0 to +45 °C, with a derating slope of 0.6/0.5 A per K up to +55 °C, the drive meets Climatic Category 3K3 standards and withstands vibrations from 2 to 150 Hz. Its IP20 protection category requires installation in an IP54-rated cabinet to safeguard against dust and moisture ingress. Backed by a one-year warranty from Wake Industrial, the DM 45K 4101-D offers reliable servo drive performance for global automation applications.
