Product Description:

The DM 030K 1101-D servo drive module is engineered by Bosch Rexroth Indramat for its DM Servo Drives series. The unit converts the intermediate DC bus into precisely modulated three-phase voltages so that industrial motors follow commanded speed and torque profiles. By integrating into multi-axis machines, it acts as the actuator side of motion loops in material handling, printing, and coordinated axes.

In operation, the drive draws 1.03 A from the control-level 24 V supply that feeds its logic and gate circuits. The main DC link is maintained at 670 VDC when regulated and can rise to 715 VDC on an unregulated bus, providing headroom for fast torque steps. A factory switching frequency of 8 kHz shapes the pulse-width modulation, and the output can deliver up to 30 A rms at 2 kHz before thermal limits impose derating. At that 8 kHz carrier, the slope is 0.24 A/K, whereas a 4 kHz setting produces a larger 0.35 A/K drop per kelvin. Heat produced by the power semiconductors totals 156 W, so the enclosure must provide enough airflow to remove losses during sustained operation.

Control data reach the drive through the SERCOS fiber-optic setpoint interface, while a standard encoder connection accepts incremental feedback up to 1 MHz and dedicated sine reference signals to 50 kHz or combined sine and cosine tracks to 800 kHz. Internally, the motion controller interpolates positions with 32 bits of mounting resolution, 20-bit staging resolution, and 12-bit resolver conversion, supporting tight contour tolerances. The specified air cooling path evacuates switch-stage heat without liquid auxiliaries, so adjacent drives in a shared enclosure can rely on the same airflow. This combination supports precise, high-speed positioning in pick-and-place heads, feeders, and small machining centers.
