Product Description:

The DMA 45A 4201-D is a drive module produced by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. It is intended for cabinet-mounted multi-axis racks where it supplies regulated power to synchronous or asynchronous motors in automated machinery. By converting the incoming three-phase line into controlled DC and a pulse-width-modulated output stage, the unit lets motion controllers apply precise torque, speed, and position commands on connected axes without external amplification hardware.

This module expels heat through backplane air cooling, so airflow drawn along the rear of the rack keeps the power electronics within temperature limits without dedicated fans on the front panel. For rotor position feedback, it accepts a gear encoder signal, enabling direct connection to gear-integrated encoders used on many mechanical transmissions. Command values reach the drive over an analog interface with 16-bit resolution; the high word length allows tight velocity or torque loops because even small reference changes are distinguishable. Its slim mechanical outline is fixed at 50 mm in width, letting several modules share a single backplane without exceeding common 300 mm cabinet depths. Internally, the unit uses the Servodyn-D series code so higher-level controllers can load the matching parameter set automatically.

No application-specific extras are built in, and the unit has no additional functions. The product type tag lists it as a 3-phase module, confirming compatibility with both synchronous and asynchronous motors that rely on a balanced three-line supply. The hardware ordering key identifies this unit as the standard variant, meaning protective circuitry and I/O count follow the baseline configuration with no customized extensions. Its electrical and mechanical footprint follows the standard format used for this module type.
