Product Description:

Bosch Rexroth Indramat manufactures the TDM3.2-030-300, a servo drive module in the TDM Servo Drive Modules series. The unit converts fixed DC-link energy from a supply module into controlled three-phase power so that synchronous and induction motors can follow precise speed and torque commands in automated machinery. In a rack-mounted drive cabinet, the module occupies a 70 mm-wide slot and interfaces with Indramat command electronics through standardized control leads. This arrangement supports closed-loop current regulation for material-handling axes, packaging lines, and process equipment, and it allows each axis to receive controlled motor power from a shared cabinet supply structure.

It delivers a continuous output of 25 A, allowing motors to operate under rated mechanical load without thermal drift, and it withstands transient demands up to 30 A so acceleration profiles are not limited by the controller. The internal power stage is supplied from a shared DC bus at 300 VDC; this voltage sets the maximum motor back EMF the system can tolerate and influences insulation coordination inside the cabinet. With a conversion capability of 9 kW, the drive can power medium-frame servomotors in pick-and-place gantries or compact spindle stations. Cooling air is drawn through the heat sink by fans, and this forced ventilation method maintains semiconductor temperature and keeps current feedback stable for precise measurement.

During operation, the module dissipates 175 W as heat, so cabinet airflow must account for adjacent equipment and leave a clear path for heat removal. It remains fully rated in ambient temperatures up to 55 °C, and no derating is required at installation heights up to 1000 m above sea level when cabinet pressure drop stays within limits. The aluminum housing weighs 8 kg. Its 390 mm height and 355 mm depth allow the module to slide into maintenance rails without requiring unusual cabinet depth or added mechanical support.
