Product Description:

The DMA 30A 6111-D is a drive module manufactured by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. It serves as the power section for one motor axis, converting three-phase mains power into controlled output for synchronous or asynchronous servo motors used in industrial handling, packaging, and assembly stations. Integrated logic allows the module to execute motion commands issued by a higher-level controller, making it suitable where compact single-axis control is required.

This module uses backplane air cooling. Heat sinks vent through the rear, so cabinet airflow must be directed across the rack. The housing is only 50 mm wide, enabling dense installation of multiple axes inside a standard 19-inch frame. Communication with decentralized I/O and PLCs is possible through the PROFIBUS-DP option card, which provides deterministic fieldbus exchange for command, status, and diagnostic words. For stand-alone systems or indexing tables, the built-in motion block supports One Axis Positioning, so homing, target moves, and velocity profiles can be executed without an external motion card. Electrically, the unit is a three-phase module for synchronous and asynchronous motors, supplying the current waveforms and regenerative handling needed by both motor types during acceleration and braking.

Feedback from the motor is evaluated through a standard interface, allowing common incremental or absolute encoders to close the servo loop. Within larger Servodyn racks, it operates as part of the Servodyn-D series, using compatible wiring and a common parameter structure across axes. This unit is the standard variant, so its safety relays and monitoring circuits match the base catalog configuration. When integrated with other axes, the same cooling direction, fieldbus behavior, and feedback handling help keep cabinet layout and setup consistent.
