DMA 45A 5111-D

DMA 45A 5111-D, Bosch Rexroth Indramat, DMA Servo Drive Modules represents a high-performance three-phase drive module designed for precise speed, torque, and position control in industrial automation. This module features an advanced IGBT inverter output stage that securely stores drive data and supports cascade control of current, speed, and position regulators. Compact yet robust, the drive houses a dedicated supply module for energy recovery and a backplane plug connector for seamless integration with additional Servodyn-D axis and supply units. Its modular architecture ensures rapid commissioning and adaptation to diverse motor types, while the built-in protective functions guard against overvoltage and electrical noise.

Within its narrow 50 mm width and 521 mm height enclosure, the DMA 45A 5111-D accepts an Input Voltage of 670 V and delivers a regulated Output Voltage of 400 V. The drive’s 24 VDC current input rating of 1.32 A powers internal controls and diagnostics, while an optical Sercos interface ensures deterministic communication via waveguide isolation. The module’s fast response time processes actual values and setpoints within a single control cycle, eliminating latency in high-speed applications. An integrated energy-recovery supply module captures braking energy, reducing external resistor requirements and improving overall system efficiency. Rugged mechanical design and high-density power electronics enable sustained performance under demanding load profiles.

Engineered for fault-tolerant operation, the DMA 45A 5111-D leverages optical isolation in its Sercos link to maintain signal integrity in electrically noisy environments. Its plug-in backplane connectivity simplifies system upgrades and spare-parts replacement, minimizing downtime in multi-axis setups. Ideal for integration with asynchronous, synchronous, or linear servo motors, this drive module delivers reliable, high-precision control across packaging machines, metal-forming lines, and robotics applications.
