Product Description:
The TDM 1.2-030-300W1 is a servo drive module produced by Bosch Rexroth Indramat in the TDM Servo Drive Modules series. Deployed between a supply rectifier and a synchronous motor, it converts the regulated DC bus into controlled three-phase power. This allows automated machine axes to achieve accurate velocity, torque, and position loops.
The drive supplies a continuous motor phase current of 30 A, allowing mid-range servomotors to remain at full rated torque without excess heating. The module has a mechanical output capability of 9 kW, matching grinders, packaging axes, or woodworking spindles that demand sustained power. An internal power section tied to a 300 VDC link simplifies common-bus installations and stabilizes dynamic braking energy. Forced-ventilation cooling is provided by an integral fan that draws 30 VA from the auxiliary line, while total converter dissipation is limited to 190 W, which must be extracted by cabinet airflow. The peak current equals the continuous value, indicating that the module is intended for steady-state duties rather than short overload bursts. Control electronics are fed from dedicated ±15 V rails; the board draws 140 mA on the positive line and 60 mA on the negative, and up to 15 mA from each polarity can be routed to external sensors. Insulation category C separates live conductors from ground for the specified bus voltage.
Rated performance is maintained up to 55 °C ambient and at altitudes not exceeding 1000 m above sea level, provided the cabinet maintains the prescribed airflow. The housing carries a protection rating of IP10, so access to energized parts is prevented, but an additional enclosure is required in dust-laden areas. At 10 kg, the module remains relatively compact while still supplying the thermal mass needed for stable operation.
