Product Description:

The TDM 1.2-100-300-W1-000/S100 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. The device functions as the power-processing stage between a machine controller and an AC motor, delivering regulated DC link energy and closed-loop current control that are essential in industrial automation. By modulating motor torque in real time, the unit helps coordinate precise axis movements in equipment such as pick-and-place gantries, metal-cutting spindles, and packaging lines.

Under continuous duty, the module supplies 65 A of motor phase current, which it can sustain without overheating. That output corresponds to 30 kW of continuous mechanical power when paired with the motor load. Heat generated by the switching devices is removed through forced ventilation, permitting stable operation while keeping component temperatures within limits. The internal link circuit operates at DC 300 V, providing the intermediate energy reservoir from which the output stage draws. For rapid accelerations, both the peak current and the type current are rated at 100 A, giving short-term torque headroom. Low-level services include an external ±15 V reference source limited to 15 mA, and two signal loads draw 60 mA at −15 V and 140 mA at +15 V to supply encoder and logic circuits.

During operation, the unit dissipates 400 W of internal power that must be removed by the cabinet airflow path. It remains functional in ambient temperatures up to 55 °C and at installation altitudes of 1000 m, which helps determine enclosure cooling needs. An IP 10 housing provides basic touch protection, while the C-class insulation system withstands elevated winding temperatures. Control wiring is supported by a ready contact rated at 24 V / 1 A for clear status signaling to the main controller. The module weighs 10.5 kg, allowing panel mounting without heavy support hardware.
