Product Description:
The TDM 1.2-030-300-W1 servo drive module is produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It mounts beside a supply unit to form the axis controller that powers and regulates brushless motors on transfer lines, presses, and packaging stations. By converting DC bus energy into timed three-phase output, the unit issues torque commands for precise positioning tasks in industrial automation. This layout is typical of modular drive systems where the supply unit and axis module are installed side by side in a control cabinet. Used with a matching supply section and motor feedback, it supports closed-loop speed and position control during repetitive machine cycles.
The power stage delivers a continuous phase current of 30 A, and the connected motor can absorb up to 9 kW without exceeding thermal limits. Energy is taken from a bus stabilized at 300 VDC, and within this range the IGBT bridge modulates pulses across the full speed band. This arrangement lets the inverter maintain commanded motor current during acceleration, steady running, and deceleration. An auxiliary fan inside the module draws 30 VA, moving air across the heat sinks to keep the internal temperature below 55 °C. The airflow is internal, so cabinet ventilation still has to remove the heat discharged by the module. The control electronics use ±15 V supply rails and load the cabinet supply with 60 mA on the negative side and 140 mA on the positive side. The asymmetric low-voltage demand should be considered when sizing the auxiliary supply. The drive weighs 10 kg, uses insulation category C materials, and carries humidity class F so varnished components can tolerate moisture during startup.
The drive dissipates 190 W as heat and uses forced ventilation to remove it. This cooling method supports installation elevations up to 1000 m without current derating. The housing has an IP10 protection rating, so the module should be installed in a filtered cabinet because the enclosure is not sealed against dust ingress. The cabinet should also protect the unit from direct contamination while allowing enough airflow for the cooling path.
