Product Description:
The DMA 45A 3301-D servo drive module is manufactured by Bosch Rexroth Indramat as part of the DMA Servo Drive Modules series. Intended for mounting on a shared DC bus, the module interfaces directly with axis controllers to generate controlled three-phase outputs for factory machinery. It regulates motor current so commanded motion profiles can be followed during indexing, conveying, and positioning tasks. Because the power stage and control interface are housed in one module, the drive can respond quickly to reference changes from the higher-level control system. This operating role makes it suitable for packaging lines, material handling systems, and other automated equipment that depend on accurate speed control and repeatable axis response.
Thermal management relies on backplane air cooling, which draws cabinet air across the heat sink through rear plenums instead of requiring a separate external blower at the front of the rack. Motor feedback connectivity is provided through a resolver interface, giving the drive a durable method of reporting rotor position and speed for closed-loop operation. Command values and diagnostic data are carried over an analog channel with 12-bit resolution, which provides 4096 discrete reference steps for reference processing. The housing occupies only 50 mm of rack width, and the drive belongs to the Servodyn-D series used in modular multi-axis systems. This narrow format is useful in cabinets where several servo axes must fit within a limited horizontal span.
As a 3-phase module, the DMA 45A 3301-D can operate with both synchronous and asynchronous motor windings without additional plug-in boards. The unit is supplied as the standard variant. That flexibility allows one cabinet platform to serve mixed motor applications without changing the basic drive footprint. Its compact rack format suits dense cabinet layouts where several axes share common power distribution and central control hardware. The module is intended for centralized installations where multiple motion channels are grouped in one enclosure for coordinated machine operation.
