Product Description:

The TDM 1.2-100-300-W1-220/S102 is a servo drive module manufactured by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. In an automation cell, it interfaces with Indramat power supplies and servo motors, converting DC link energy into controlled three-phase output so speed and torque follow the machine controller’s commands. By integrating power conversion, monitoring, and a built-in cooling circuit, the unit supports high-cycle positioning tasks on metal-cutting machines, printing lines, and material-handling axes.

The drive is rated for a peak current of 100 A and can deliver a continuous output of 65 A without derating. These currents are sourced from a link circuit held at DC 300 V, allowing the converter to reach a nominal shaft output of 30 kW. Internal switching losses, magnetic losses, and the fan itself generate about 400 W of heat, so a built-in fan operating from 220 V AC at 50–60 Hz removes heat through the heat sink fins. The cooling assembly matches the module’s flush-mount style, so air exits into the cabinet channel required by DIN VDE 0160 clearances. Class F humidity protection helps the electronics tolerate condensation up to 100% relative humidity during nonoperation, and insulation category C spacing keeps live parts separated under the same service conditions.

Thermal derating begins only above 55 °C ambient, making the unit suitable for cabinets that reach elevated temperatures during full-load operation. The enclosure carries an IP10 rating, so airflow is unrestricted while fingers and large debris are kept away from energized conductors. At a mounting altitude of 1000 m, power delivery remains unchanged. The module has a mass of 10.5 kg, which should be considered for support rails and mounting. The flush hardware pattern anchors the chassis securely while allowing the fan to operate at its rated 50–60 Hz frequency.
