Product Description:
The TDM2.2-50-220/300-W1-220/380 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. Installed in multi-axis cabinets, it forms the interface between the supply section and the motor phases, rectifying and regulating power so that synchronous and asynchronous servo motors follow commanded motion profiles. In industrial automation cells, the module manages acceleration, deceleration, and holding functions, allowing machine tools, handling gantries, and packaging stations to coordinate motion under PLC supervision.
The unit feeds its control logic with AC 220/380 V, which allows the same hardware to operate from either European or North American auxiliary supplies. During operation, the power section draws a rated current of 50 A and delivers energy to a shared DC bus maintained at DC 300 V, which balances motor response with semiconductor stress. Excess regenerative energy is removed by a bleeder resistor that can dissipate 450 W continuously and reach a short-term peak of 10 kW, helping prevent overvoltage during rapid braking. Internal losses are limited to 580 W, and the IP10 housing relies on forced-air channels inside the rack. The module has a 15 kW power rating, and a 30 W fan section at 220 V provides the airflow required for continuous cooling.
In dynamic cycles, the DC link can absorb returned energy up to 14 kWs before the resistor engages, which supports repetitive positioning moves. The drive supplies a nominal load output of 8 A and can deliver a peak of 150 A for brief acceleration bursts without losing regulation. Safe thermal operation is permitted up to 55 °C ambient when cabinet ventilation is maintained. The 15 kg chassis supports secure rack mounting, and the module should be installed inside a protected enclosure with sufficient airflow.
