Product Description:

The TDM2.1-030-W0 is a servo drive module built by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. Installed between the mains supply and an Indramat servo motor, the unit converts a fixed DC bus into controlled three-phase output that regulates speed and torque in automated machinery. This control function supports repeatable motion on machine axes that must accelerate, hold speed, and respond cleanly to changing load conditions. Because it operates without additional cooling hardware, it suits compact control cabinets where natural airflow is the only available heat path.

The power section delivers a continuous phase current of 25 A, enabling the drive to supply motors that draw steady power up to 9 kW. Internally, the energy reservoir is a DC link stabilized at 300 VDC, and the rectifier section accepts mains deviations within a tolerance of ±15% before derating occurs. Control electronics monitor auxiliary rails that draw 60 mA from −15 V and 140 mA from +15 V, while external sensors can be powered by an additional ±15 V source limited to 15 mA. Thermal dissipation relies on natural convection, and a moisture-resistant Class F varnish helps protect the windings during operation. This arrangement supports steady output in cabinets that rely on passive airflow instead of forced ventilation.

During acceleration, the current limit briefly rises to 30 A, giving extra torque for overcoming static friction. At that load, the converter’s internal losses reach 160 W. The housing carries an IP 10 rating that blocks large objects while remaining open to convective airflow. Reliability is maintained up to 55 °C ambient and 1000 m installation altitude, provided the unit is mounted vertically so warm air can move upward through the enclosure. The steel chassis weighs 9 kg, which supports secure panel mounting without requiring additional framing or vibration isolation.
