Product Description:

The TDM 2.1-030-300-W1-220/S101 servo drive module is manufactured by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. Installed between the mains supply and a compatible Indramat servo motor, the unit converts line power, monitors feedback, and delivers regulated current so automated axes can maintain speed and torque targets during machining, conveying, packaging, and similar motion-control cycles. Its role in the drive system is to provide controlled motor operation in applications that require repeatable motion, steady electrical performance, and accurate response to changing load conditions.

The drive supplies a continuous output of 30 A, allowing stable operation for motors sized to the module. Internal power conversion is referenced to a link circuit of DC 300 V, and the control electronics tolerate a voltage swing of ±15% to ride through moderate line variations without tripping. Thermal energy from the switching devices is removed by a built-in fan; that fan is powered from an external 220 V AC connection and helps keep semiconductor junctions within their rated limits. With a rated shaft power of 9 kW, the module supports medium-duty positioning tasks. Current sensing relies on minus 15 V and plus 15 V rails that draw 60 mA and 140 mA respectively for amplifier logic, and insulation category C spacing is used between the power and control sections to resist transient electrical stress during operation.

The drive is intended for ambient temperatures up to 55 °C and installation elevations of up to 1000 m before derating is required. Within those limits, it dissipates 190 W of internal power loss, a value that is useful for cabinet ventilation planning. Protection level IP10 helps prevent accidental contact with live parts but requires mounting inside a closed electrical enclosure. Humidity class F materials permit operation at 95% relative humidity without condensation, which supports use in enclosed industrial cabinets exposed to normal moisture variation.
