Product Description:

Bosch Rexroth Indramat manufactures the TDM1.2-30-300-W1/220, a servo drive module in the TDM Servo Drive Modules series. The module forms the power interface between a regulated DC link and a matched servo motor, providing controlled current that drives axes in numerically controlled machinery and automated handling lines. By converting stored DC energy into precisely timed motor current, it helps maintain commanded velocities, accelerations, and positions within closed-loop motion systems commonly found in industrial automation cells.

The power stage sustains a continuous motor current of 30 A while operating from a DC link potential of 300 VDC. At this rating, the module can support motor output up to 9 kW when paired with a compatible servo motor. Thermal energy is removed by forced ventilation, and an internal axial blower moves air across the heat sinks whenever the unit is enabled. That blower is energized from the drive’s auxiliary supply of AC 220 V, keeping semiconductor junctions within safe limits during full-load operation. These values describe the module’s continuous operating conditions during closed-loop motion control.

The remaining service limits apply to installation and auxiliary supply requirements. The cooling fan draws 30 VA, and the control electronics consume 140 mA at +15 V and 60 mA at −15 V. Total internal dissipation reaches 190 W, so cabinet airflow must accommodate that heat. Maximum ambient temperature is 55 °C, and mounting height is permitted up to 1000 m above sea level. The housing has an IP10 protection class, indicating open airflow slots and a need for a clean enclosure. With an insulation assignment of category C and a mass of 10 kg, the module can be panel-mounted beside companion supply units while keeping structural load and creepage distances within accepted design margins. Peak output current equals the continuous rating.
