Product Description:
The DMA 030A 5111-D servo drive module is manufactured by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. Designed as a three-phase module for synchronous and asynchronous motors, it supplies regulated energy to a single mechanical axis while coordinating motion through internal positioning functions. In industrial automation cabinets, the device links to the supply unit through a common DC bus and communicates setpoints with 24 V control signals to close the motion loop.
The module operates from a DC link that can rise to 715 VDC in non-regulated operation and is maintained at 670 VDC when the supply is in regulated mode; these voltages provide the energy buffer for dynamic motor currents. At a carrier frequency of 4 kHz, it can deliver a peak phase current of 35 Arms, while the same load profile at 8 kHz is limited to 32 Arms. Thermal limits are managed by air cooling through the backplane and a derating gradient of 0.46 A per kelvin. Internal switching and magnetics dissipate up to 180 W of power, a figure that must be removed by enclosure airflow to keep semiconductor junctions below their design temperature.
Mechanical integration is supported by a mass of 7.3 kg, a slim 50 mm front width, and a cabinet depth allowance of 504 mm so the unit can be dismounted without disturbing adjacent hardware. The overall height reaches 521.5 mm, permitting direct stacking with matching drives on the same backplane rail. Absolute encoder data from connected motors are processed with 32 bits of multi-turn resolution, while a separate 20-bit channel covers single-turn feedback to support the built-in one-axis positioning function. Control electronics draw only 1.23 A from the 24 V supply, leaving headroom for I/O modules that share the auxiliary bus and helping the drive fit dense cabinet layouts.
