Product Description:
The TDM 2.1-30-300-W1/S0101 is a servo drive module from the TDM Servo Drive Modules series manufactured by Bosch Rexroth Indramat. As a regulated power stage, it interfaces between the plant’s DC bus and an AC servo motor, modulating current to achieve precise velocity and torque control in industrial automation cells. The unit occupies a single slot in the modular drive rack and works with compatible supply modules to form a closed-loop axis. Its role is to translate command words from the motion controller into high-bandwidth current commands that keep position loops stable during indexing, packaging, or material-handling sequences.
Its nominal operating range includes a continuous current of 30 A, which is the sustained phase current the module can deliver without thermal drift. The converter is energized from a DC link maintained at 300 VDC, and from this bus it can supply a continuous mechanical output of 9 kW to the connected motor. Thermal energy from the switching elements is removed by forced ventilation, and an internal blower draws 30 VA from the control cabinet auxiliary circuit to keep the heat sinks within limits. Application peaks can rise momentarily to 30 A because the rated, peak, and continuous current limits are identical. For installation, it may be mounted up to 1000 m above sea level before derating is required, and operation is permitted until the surrounding air reaches 55 °C.
Electrical efficiency is supported by a conduction loss figure of 190 W, a value that helps determine cabinet cooling airflow. Control electronics inside the module draw two bipolar supply rails; the −15 V rail carries 60 mA while the +15 V rail carries 140 mA, allowing compact logic supplies to be shared among multiple axes. Humidity class F and insulation category C indicate permissible moisture levels and dielectric spacing for the power components. The housing carries a protection rating of IP 10, so it must be installed inside a closed cabinet to avoid intrusion of tools or debris. A mass of 10 kg supports stable cabinet mounting without extra bracing.
