Product Description:

The TDM2.1-30-300-W1/S0101 is a servo drive module produced by Bosch Rexroth Indramat and supplied within the TDM Servo Drive Modules series. In automated machinery, the unit converts DC bus energy into regulated three-phase output for matched Indramat motors so that positioning, speed, and torque loops can be executed by the higher-level controller. It is intended for cabinet-mounted motion systems that use a shared power architecture. This arrangement helps separate drive power conversion from the control layer while keeping the motor supply local to the axis cabinet. A radial blower fixed on the module channels air along the fin stack, and the housing depth of 355 mm keeps the thermal path short.

This drive can deliver a continuous output of 9 kW while drawing up to 30 A of motor phase current from its power stage. Energy is taken from a shared supply at a DC link potential of 300 VDC, giving the drive a mid-range operating window suitable for factory distribution buses. Under rated load, the internal electronics and switching devices dissipate 190 W as heat, and the forced-ventilation cooling path moves air through the heat sink to keep semiconductor temperatures within their limits. Humidity class F impregnation and insulation category C materials withstand condensation and corona that may form during repeated start-stop cycles. Weight is held to 10 kg so the module can be installed on light-gauge cabinet backplates without additional bracing.

The cooling fan consumes 30 VA, and its exhaust path requires a minimum vent clearance of 80 mm above the unit’s top edge. Overall frame height measures 390 mm and width is 60 mm, enabling dense side-by-side mounting in shallow enclosures. The drive continues to function at ambient temperatures up to 55 °C and at installation elevations not exceeding 1000 m, provided cabinet airflow is maintained. External ingress protection is rated at IP10, so the module must be installed inside a dust-shielded panel. The control electronics remain isolated from the cooling channel by conformally coated boards.
