Product Description:
The DMA 85B 5311-D is a servo-drive power module manufactured by Bosch Rexroth Indramat as part of the DMA Servo Drive Modules series. It is intended for cabinet installation, where it forms the drive section of an automation axis and converts three-phase mains power into regulated output for motion tasks. When paired with a compatible control unit, the module manages current, velocity, and position loops for motors used in conveyors, packaging systems, and handling stations. Its role is to supply controlled power to the motor while the higher-level control handles overall axis coordination. This arrangement supports repeatable acceleration, deceleration, and stable motion during routine machine cycles.
This module is a three-phase converter that can energize synchronous and asynchronous motors without additional hardware changes. Position and speed feedback are processed through a dedicated resolver interface, allowing the drive to monitor rotor angle reliably even at zero speed. Thermal management relies on backplane air cooling, so heat is directed away through the rear heat sink rather than by front-mounted fans. Command inputs arrive as 24 V control signals, which supports direct connection to standard PLC I/O and keeps control wiring straightforward. The compact power section also helps maintain orderly multi-axis cabinet layouts where several modules are installed side by side.
A housing width of 100 mm leaves room on the mounting rail for adjacent protective or interface components in compact cabinets. The module supports single-axis positioning, allowing basic motion sequences to be handled locally while a higher-level controller supervises the machine process. Compatibility with the Servodyn-D series backplane allows power sharing and common DC bus operation among drives with different output ratings. The unit is supplied as a standard variant, which uses the base current range and default parameter set for general servo applications. This configuration suits installations that need straightforward integration with established servo hardware.
