Product Description:

The TDM 1.4-100-300-W1-000 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. The unit converts energy from a shared DC link and supplies controlled current to coordinated servo motors on automated lines, material handlers, and process machines. It acts as the intermediary between the line-fed supply and the motor windings, delivering command-based power while supervising internal temperature and electrical limits. It is commonly used where several servo axes share one supply section and require fast, stable current regulation during synchronized motion.

The drive supplies a continuous current of 65 A, enabling sustained operation of high-torque axes without derating. Its rated continuous output power is 30 kW, delivered through a link circuit held at 300 V. Thermal energy is removed by forced ventilation, which moves cabinet air across the heat sinks. For short load surges, the peak and type current both rise to 100 A, giving the connected motor additional acceleration headroom. Stable current delivery helps the motor maintain commanded torque when the axis sees abrupt load changes. This operating range supports repeated starts, stops, and speed changes in demanding motion cycles.

The insulation follows category C, and safe ambient operation is allowed up to 55 °C provided installation altitude does not exceed 1000 m. Internal electronics provide +15 V at 15 mA and -15 V at 15 mA for external loads, while the logic section consumes 140 mA from the positive rail and 60 mA from the negative rail. The housing has an IP10 protection rating, with ventilation openings that block large objects while allowing cooling air to pass. During full output, the converter dissipates 400 W as heat, and its assembled mass is 10.5 kg. The auxiliary supply rails support connected control circuitry, and the module's mass matters when it is mounted in a vertical rack. These values affect cabinet airflow planning and the amount of support needed for secure mounting.
