Product Description:

The DMA 45A 1301-D is a servo drive module produced by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. It serves as the power and control link between a higher-level controller and both synchronous and asynchronous motors, converting three-phase mains energy into regulated motor currents for speed and torque control in automated machinery. By combining the power stage, control electronics, and field wiring in a narrow housing, the device supports high-density multi-axis layouts while keeping control and power functions in one module.

With a compact module width of 50 mm, the drive occupies a single cabinet slot and leaves space for adjacent amplifiers. Heat is removed through backplane air cooling, so airflow along the rear rail passes over the integral heat sink while front wiring remains accessible. Motor feedback arrives through a Resolver, which supplies rotor position signals without an auxiliary encoder supply. Deterministic motion control is handled through the SERCOS interface, allowing cycle-synchronous parameter exchange with the central PLC. As a three-phase converter, it directly energizes synchronous or induction motors from a balanced mains input, which supports compact cabinet integration without requiring separate output stages.

This module belongs to the Servodyn-D series and is intended for use with shared backplane power supplies and coordinated communication structures. It is delivered as the Standard Variant, which uses the baseline feature set for this product family. The module has no additional functions, so the configuration remains focused on core drive operation and motor feedback handling. The dedicated cabinet slot helps keep wiring organized and preserves clear airflow between neighboring modules.
