Product Description:
The DMA 30A 6311-D drive module is produced by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. Designed for rack installation inside machine cabinets, the module supplies regulated three-phase power to one motor axis by drawing energy from a shared DC bus. In industrial automation cells, it closes the speed and torque loop for synchronous or asynchronous motors so that conveyor sections, rotary tables, and pick-and-place heads follow programmed motion profiles with repeatable accuracy during normal operation. Its single-axis layout also suits compact multi-axis systems that share common power infrastructure within the same cabinet.
Thermal management relies on backplane air cooling, which transfers heat through the rear panel into the cabinet airflow path. Motor feedback is accepted through a resolver interface, giving rotor position information across the full speed range without battery backup. For plant-wide coordination, the module offers an option slot that supports PROFIBUS-DP, enabling real-time setpoint exchange and diagnostic reporting to PLCs. The housing occupies only 50 mm of width on the mounting rail, conserving space in multi-axis racks. Integrated firmware enables one-axis positioning, allowing indexed moves or homing sequences without an external motion card.
The hardware is classified as a three-phase module for synchronous and asynchronous motors. Its electrical flexibility allows it to energize permanent-magnet and induction machines within the same platform. Internally, the unit carries the identifier of the Servodyn-D series, which matches it to compatible backplane-cooled supply and brake modules in that family. This unit is supplied in the Standard Variant, providing the baseline option set used on typical machine-tool and handling axes. Bosch Rexroth Indramat uses uniform connectors, menu structures, and diagnostic codes across this product range, which helps keep integration consistent from one axis to another.
