Product Description:
The DMA 85B 9101-D servo drive module is produced by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. It occupies a single slot on the system backplane and converts the shared DC link into individually regulated three-phase outputs for coordinated motion. Within an automation cell, the module follows higher-level commands to start, stop, and position motors that move loads, tooling, or product carriers. This arrangement allows each axis to receive controlled power while remaining part of a multi-axis drive system.
Thermal management relies on backplane air cooling, which transfers heat through the rear mounting plane where filtered cabinet air removes it from the heat sink. Fieldbus connectivity is provided through CANopen and CANrho, allowing status, parameter, and command data to move between the drive and the controller without additional option cards. The internal resolver and encoder port uses a standard interface, so compatible feedback devices can be connected without adapters. Cabinet layout is also shaped by the fixed front-panel width of 100 mm, which sets slot spacing and helps maintain consistent airflow between neighboring drives.
This unit has no additional functions, so no braking chopper, safe torque off, or I/O expansion is installed at the factory. Its classification as a 3-phase module for synchronous and asynchronous motors confirms compatibility with both permanent-magnet and induction motor designs without hardware changes. It is grouped under the Servodyn-D series, and it is described within that platform as one of the available axis modules. The unit is the Standard Variant, which indicates the default current rating and connector set used for this model. These traits keep the module aligned with the established layout and operating format used across the platform.
