Product Description:

The TDM 1.2-100-300-W1-000 is a drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It converts link-circuit DC energy into controlled three-phase outputs so that servomotors can be positioned and regulated in automated machinery. By integrating current regulation, a cooling fan, and protective monitoring into one enclosure, the module provides a compact component for cabinet-mounted motion axes in transfer lines, presses, and packaging systems.

Its continuous phase current capacity reaches 65 A, enabling sustained torque production from connected motors under rated load. For short acceleration bursts, the module can deliver a peak current of 100 A. The continuous power handling capability is 30 kW, while a power loss of only 400 W at that load helps maintain thermal margins. A link-circuit voltage of 300 V ±15 % is accepted from the supply section, and the internal control converts a 0.050 V/A current setpoint signal into the required output, allowing a straightforward analog interface with motion controllers. Forced ventilation is provided by a built-in fan whose supply is generated within the unit, so no external blower wiring is required. The housing provides IP10 protection, and the insulation materials support elevated winding temperatures during heavy-duty operation.

Operation is permitted up to 55 °C ambient and at mounting elevations not exceeding 1000 m before derating applies. The insulation system is rated as category C, which supports higher winding temperatures during cyclic duty. At startup, the current regulator cannot be adjusted below the minimum Ired current of 15 A, which helps maintain measurement resolution at low load. The module has a mass of 10.5 kg, and its integrated ventilation package maintains airflow without relying on cabinet fans.
