Product Description:

The TDM 7.1-030-300-W1/S102 servo drive module is produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It is a dedicated power stage that converts a fixed DC link into controlled three-phase output for synchronous or induction motors, enabling precise speed and torque regulation in automated machinery and material-handling cells. By integrating the command and power electronics in one housing, the unit simplifies cabinet layout and provides the closed-loop interface needed for coordinated motion control. This arrangement helps the drive respond consistently to changing load demand during acceleration, steady running, and deceleration.

For continuous operation, the module can deliver a maximum phase current of 12 A, corresponding to a steady mechanical output of 9 kW when paired with the matching motor. Energy is drawn from a shared intermediate circuit stabilized at 300 V DC, which supports operation within a common drive system. Short acceleration bursts are covered by a peak current of 30 A, after which the integrated thermal model limits conduction to protect the power section. Internal losses are limited to 135 W, and that heat is removed by a built-in fan powered from the drive’s own auxiliary rail, so no external blower wiring is required. The electronics use a conformal coating rated for Humidity Class F, which helps protect the circuit surfaces in production areas with elevated moisture.

Mechanical integration is supported by a housing mass of 6.5 kg, which keeps the unit manageable during cabinet installation. Full-rating output is maintained until the ambient cabinet air reaches 55 °C; above this point, the drive applies derating to protect semiconductor junctions from excessive heat. Elevations up to 1000 m above sea level are permitted without changes to the cooling setup, which suits most industrial sites. An enclosure rating of IP10 indicates basic protection against accidental contact with live parts, so the module is intended for installation inside a closed electrical cabinet. That cabinet also provides the additional shielding and containment needed for safe operation in an industrial environment.
