Product Description:

The TDM 1-2-100-300W1-220V servo drive module is built by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It is a line-supply converter that conditions three-phase power for permanent-magnet or induction motors in automated machinery. By regulating current and DC bus voltage, the unit enables closed-loop speed and torque control in conveyor, packaging, and material-handling cells. The module is intended for installation inside an electrical cabinet, where the power section and control wiring can remain protected from the surrounding production area.

During continuous operation, it delivers a motor phase current of 65 A, while its rated DC link supports 30 kW of sustained power transfer. An internal rectifier charges the bus to DC 300 V, and the control electronics can momentarily dispatch up to 100 A of pulse current for acceleration demands. Losses generated in the IGBT stack and filter network amount to 400 W, which the built-in fan expels to maintain component temperatures. The cooling assembly is driven by an AC blower connected to a 0.315 A / 250 E fuse and protected under Humidity Class F. The housing has a height of 325 mm and a width of 105 mm, allowing dense cabinet layouts within the stated 1000 m altitude limit.

The ventilation circuit draws its supply from AC 220 V and consumes 30 VA, ensuring steady airflow across the heat sink without imposing significant load on the facility mains. Enclosure ingress protection is limited to IP10, so the module must be mounted in a filtered electrical bay free of conductive dust. With a transport mass of 10.5 kg, the unit can be mounted with standard rail hardware in a properly supported enclosure. The side-panel dimensions leave clearance for bus bars and control harnesses, while the fan fuse’s 0.315 A rating helps protect the blower circuit. Operation is permitted up to Humidity Class F, which helps maintain the dielectric strength of the control circuits under typical plant ambient conditions.
