Product Description:

The TDM 2.1-030-300-W1-220/S102 is a servo drive module from Bosch Rexroth Indramat in the TDM Servo Drive Modules series. In an automation cell, this unit supplies controlled DC power to an attached motor, regulates acceleration and torque, and exchanges status signals with the higher-level controller. By integrating power electronics and monitoring circuits in a single housing, it simplifies cabinet layout and helps streamline axis setup on machine tools, packaging lines, and handling systems. Its role is to support stable motor operation while coordinating with the rest of the drive system.

The drive delivers a continuous output of 30 A, allowing motors to draw steady armature current without thermal overload, and it can sustain mechanical work up to 9 kW at rated speed. Thermal energy created by the switching devices is removed by a built-in fan that draws 30 VA from an auxiliary input and is protected by an F5 0.315 A/250E cartridge fuse. Internal capacitors smooth the DC bus, which is maintained at DC 300 V; this voltage is generated from a common three-phase supply by the associated power supply module and is shared among multiple axes. This arrangement supports consistent power delivery in systems where several drive modules operate from the same supply section.

The module tolerates ambient temperatures up to 55 °C when the fan is unobstructed, and it may be installed at elevations up to 1000 m without derating. During full-load operation, it dissipates 190 W as heat, which should be considered when planning enclosure airflow. An enclosure rating of IP10 limits mounting to clean electrical cabinets, and the unit has a mass of 10 kg. Humidity Class F coatings help resist moisture condensation, while Insulation Category C clearances provide the required spacing for the link circuit. These features support use in production machinery that operates continuously over long shifts.
