DMA 140D 1101-D

DMA 140D 1101-D, Bosch Rexroth Indramat, DMA Servo Drive Modules. The DMA 140D 1101-D is a high-performance three-phase servo drive module engineered for both asynchronous and synchronous motors from multiple manufacturers. This device features a width: 200 mm chassis and must be installed by qualified personnel. It complies with the 73/23/EEC low voltage directive and is factory-tested to rigorous safety standards. Direct connection to the power supply and approved spare parts ensure consistent, approved maintenance practices.

This servo drive delivers robust electrical performance with a Rated Current: 42 A and a Maximum Current: 142 A at a Switching Frequency: 4 kHz. The module operates on an Input Voltage: 670 V bus and produces an Output Voltage: 400 V, while its 24 VDC Current Input: 1.58 A powers control electronics. Weighing 19.3 kg, it integrates both supply and axis modules on an RMD/DM backplane and accommodates motors of Frame Size: 160. Redundant two-channel safety architecture, certified by RSU, works in tandem with air cooling for continuous operation. Standard encoder and SERCOS Interface with fault-resistant optical fibers provide real-time communication and multi-vendor interoperability.

Engineered for seamless integration, the DMA 140D 1101-D supports digital closed-loop control to regulate torque, speed, and position with high precision. Its modular plug-in personality unit allows in-field software updates without interrupting production. Rugged construction and global delivery options ensure dependable deployment across diverse applications—from machine tools to complex automation lines—where uptime and safety are paramount.
