Product Description:
The DMA 140D 5111-D is a servo drive module produced by Bosch Rexroth Indramat in the DMA Servo Drive Modules series. Designed for multi-axis automation racks, the unit conditions the DC link supplied by a central supply module and delivers controlled three-phase output to synchronous or asynchronous motors used in positioning, packaging, and material-handling stations. Within these systems, it provides power conversion, fault monitoring, and closed-loop current regulation while accepting low-level command signals from the motion controller.
Internal bus capacitors stabilize a DC link of 670 VDC, giving the drive enough headroom for regenerative braking; during transient overshoot, the link may climb to 715 VDC without triggering a shutdown. At a switching frequency of 4 kHz, the module can supply a peak phase current of 141 Arms, while an 8 kHz carrier limits the peak to 117 Arms because of higher switching losses. Continuous housekeeping and logic circuits draw only 1.58 A from the 24 V cabinet supply, and all command and feedback lines use the same 24 V signal level, which simplifies wiring to the upper-level controller. These operating limits help match the drive to compatible motors.
Under continuous operation, the drive is rated for 42 Arms at 4 kHz or 25 Arms at 8 kHz, figures chosen to keep semiconductor temperatures inside the backplane air-cooling channel. The module supports one-axis positioning, so stand-alone moves can be executed without an external PLC. Absolute feedback from encoders up to 4096 rev and a word depth of 32 bits is processed alongside resolver data at 12-bit resolution, while the SERCOS interface captures stage positions with 20-bit fidelity. The housing measures 521 mm high by 200 mm wide and slides into the series backplane with standard latching, maintaining uniform airflow between adjacent modules.
