DMA 085B 8001-D

The Bosch Rexroth Indramat DMA 085B 8001-D drive module is a core component of the DMA Servo Drive Modules series, engineered for seamless integration into the Servodyn-D fully digital inverter backplane. This three-phase module supports a nominal Input Voltage of 670 V and delivers a regulated Output Voltage of 400 V, with a 24 VDC current input of 1.35 A. Designed for both synchronous and asynchronous motor applications, it provides robust power delivery and precise control in modular inverter configurations for demanding industrial automation environments.

The DMA 085B 8001-D excels in technical performance with a maximum switching frequency of 85 kHz and a compact module width of 100 mm, optimizing rack space and thermal management. Its versatile supply module features integrated energy recovery and a mains-friendly in-feed, ensuring efficient handling of regenerative power and stable line interaction. A built-in DC link connection enables hot-swap installation of the inverter module, while dedicated air cooling (backplane mechanics) maintains optimal operating temperature without auxiliary fans. The module ships with an in-built software package to simplify commissioning and to support advanced diagnostic functions.

Additional capabilities include an onboard analog interface with 10-bit resolution and U/f characteristics, allowing high-precision analog control. The integrated processor board delivers full regulation of speed, current, and position, enhancing dynamic response and repeatability. Although there is no extra option slot or dedicated encoder interface, the module is fully compatible with standard asynchronous motors equipped with external encoders to manage U/f control profiles. Its standard variants are globally shippable, backed by a one-year warranty. These features provide industrial users with modular flexibility, enhanced reliability, simplified maintenance, and measurable efficiency gains, making the DMA 085B 8001-D an ideal choice for modern production and automation systems.
