Product Description:
The DMA 45A 5111-D drive module is produced by Bosch Rexroth Indramat as a member of the DMA Servo Drive Modules series. It plugs into a Servodyn-D backplane and works as a three-phase power stage for one servo axis, supplying regulated current to synchronous or asynchronous motors. Within an automation line, the device links the common DC bus to the machine actuator, letting the PLC issue motion commands while the module handles real-time current control and fault monitoring. Because the power stage is integrated into the rack system, it fits modular machine layouts where several axes operate from the same supply structure.
In operation, the module supports one-axis positioning, so a single servo axis can follow commanded target positions through the drive. Thermal management relies on backplane air cooling, and cabinet airflow across the rear heat sink removes losses from the power electronics. Command and feedback wiring uses 24 V control signals, allowing standard switchgear to handle enables, resets, and reference inputs. The hardware occupies only 50 mm of rack width, which helps conserve cabinet space in densely packed systems. Its narrow format also allows adjacent modules to be arranged closely without changing the basic rack concept. As part of the Servodyn-D series, the unit shares the common DC bus used in that platform.
The drive uses a standard encoder interface, so it can work with commonly used TTL or RS-422 feedback devices without additional adapter boards. It is described as a 3-phase module for synchronous and asynchronous motors, allowing the same module type to serve different motor technologies on the same machine. The unit is released as a standard variant, which indicates a general-purpose configuration for typical applications. Encoder feedback supports stable closed-loop operation during routine speed and position control. This arrangement is suitable for systems that combine multiple axis types within one cabinet.
