Product Description:

The TDM 2.1-030-W0 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. The device conditions power for synchronous and asynchronous motors, executing torque and speed commands issued by a higher-level motion controller. By converting regulated DC bus energy into three-phase output, it forms the link between the cabinet power supply and the mechanical axis in automated assembly lines and machining centers. In typical service, it works with a separate control system that sends motion commands while the module handles the power conversion stage for the motor.

The drive can supply a continuous armature current of 25 A, enabling machines to draw up to 9 kW of mechanical power without overheating the power stage. For brief acceleration bursts, it tolerates a peak current of 30 A, so short transient loads do not stall the axis. A controlled bus voltage of 300 V DC stabilizes the intermediate circuit, and natural convection removes heat generated by the electronics. Cabinet layout must also allow for a steady power loss of 160 W, which is dissipated through the aluminum heat sink and surrounding air. This cooling method supports continuous operation without requiring a built-in fan or liquid cooling loop.

The module maintains full output up to 55 °C ambient temperature and can be installed at elevations reaching 1000 m above sea level with no derating. Its enclosure carries an IP10 rating, offering basic protection against accidental contact but no sealing against liquids. The internal wiring follows insulation category C, which supports the DC bus with appropriate creepage distances, and the permissible relative humidity is Class F. These operating limits should be considered when the module is placed near other heat-producing equipment or in open cabinets with limited protection from moisture.
