Product Description:
The TDM 3.2-20-300-W0 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It regulates current and velocity for Indramat permanent-magnet motors in automated machinery, supplying the closed-loop torque control needed for packaging lines, material-handling axes, and similar motion tasks. Its control function helps the connected motor respond consistently to command changes and varying load conditions during normal machine operation. This makes the module suitable for coordinated axis applications that require stable torque delivery and controlled speed response across repeated cycles.
This module is energized from a DC bus held at 300 VDC, and its internal power stage can deliver up to 6 kW of continuous mechanical output when paired with a matched motor. During rapid acceleration, the drive sources a peak phase current of 20 A, while normal operation is limited by a continuous current of 15 A and a matching rated current for coordination with external fusing. Power dissipation inside the housing is limited to 110 W, and that heat is removed through natural convection, so the unit needs unobstructed airflow. A diagnostic test socket provides a measurement amplifier ratio of 0.375 V/A, so actual motor current can be checked at the test point without opening the control cabinet. Additional logic supply taps draw 50 mA at −15 V, 120 mA at +15 V, and 400 mA from the +24 V control rail to support tachometer feedback and relay coils.
The drive can sustain ambient temperatures up to 55 °C before derating is required, and installation is permitted at altitudes up to 1000 m above sea level without changing the stated thermal limits. At an operating speed of 2000 rpm, it maintains velocity regulation while keeping power loss within the stated margin. Protection is classified as IP10, which means live parts are guarded against accidental contact, but the enclosure is not sealed against dust. The module has an overall weight of 8 kg, which supports panel mounting in multi-axis cabinets and limits static load on the mounting surface.
