Product Description:
The TDM 2.1-030-300-W1-220 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. This unit interfaces between a DC link supply and an Indramat motor, generating controlled three-phase power for position, speed, and torque loops in automated tooling, packaging, and material-handling stations. Its circuitry manages regenerative energy and conditions low-level control signals from a higher-level CNC or PLC so motor axes stay synchronized with process requirements. It is used where a shared DC bus feeds multiple motion axes and the control system must coordinate acceleration, holding torque, and deceleration across the machine.
Electrically, the drive can deliver a continuous shaft power of 9 kW while maintaining a line-side current of 30 A under rated load. Energy passes through a DC link stabilized at 300 V, giving the power section a fixed intermediate voltage for pulse-width modulation. During standard duty, the electronics dissipate 190 W of heat, which must be removed through the integrated cooling path to keep semiconductor junctions below their temperature limit. The internal analog subsystem supplies the control circuitry with +15 V, and that rail requires 140 mA, which affects the capacity of the external logic supply when multiple drives share the same source. The fixed intermediate voltage also helps keep inverter behavior predictable during normal motion cycles.
Thermal management is handled by forced ventilation, using an axial fan powered from a 220 VAC auxiliary line that draws 30 VA and is protected by a 0.315 A/250E fuse mounted on the module. Derating begins above 45 °C, and operation is still allowed up to the specified ambient of 55 °C when current is reduced. Humidity class F and insulation category C apply to the mixed-voltage sections, and safe operation is supported at installation heights up to 1000 m. The negative control rail draws 60 mA, ingress protection is IP 10, and the housing weighs 10 kg for straightforward panel mounting. The fan supply, ambient limits, and panel-mounted housing all affect how the module is arranged inside a multi-axis cabinet.
