Product Description:
The DMA 45A 6311-D is a servo drive module released by Bosch Rexroth Indramat within the DMA Servo Drive Modules series. Mounted on a common DC-bus rail, it supplies power conversion and closed-loop control for rotary or linear axes in automated machinery. The device translates motion commands from higher-level controllers into accurate motor currents, enabling precise positioning, speed regulation, and torque control on production lines. This arrangement lets the module serve as the electrical interface between machine control commands and motor response during coordinated axis operation.
Control functionality is centered on single-axis positioning, so the module can execute indexed moves or jogging sequences without an external motion card. Thermal management uses backplane air cooling; the heat sink contacts the cabinet backplane and relies on forced airflow through the rack rather than dedicated onboard fans. Position feedback is accepted through a Resolver interface, giving analog sine-cosine signals for rotor angle detection. Network communication is handled by the PROFIBUS-DP port, allowing cyclic data exchange with a PLC over shielded twisted-pair cabling. Physically, the housing occupies only 50 mm of panel width, which supports dense multi-axis arrangements. Parameter handling follows the conventions of the Servodyn-D series, keeping the setup structure consistent across mixed racks.
As a three-phase module for synchronous and asynchronous motors, the DMA 45A 6311-D synthesizes three output phases with adjustable frequency and amplitude for compatible motor operation. The unit shipped here is the standard version, meaning it uses nominal current ratings and default software options without integrated regenerative or safety add-ons. When connected to a plant fieldbus, the drive exchanges process data for velocity, torque, and status words while retaining its independent positioning capability. No additional width spacers or accessory coolers are required, which helps keep enclosure planning straightforward.
