Product Description:
The TDM1.2-100-300-W1/S100 is a servo drive module produced by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. It is engineered to supply controlled current and voltage to synchronous servo motors, enabling accurate speed and torque regulation in automated machine tools, material-handling gantries, and assembly stations. By translating controller setpoints into pulse-width-modulated output, the drive forms the power interface between low-level motion commands and the electromechanical axes on the factory floor. This arrangement allows the axis to respond quickly to changing commands while maintaining stable motion control during normal machine operation.
In continuous operation, the drive provides 65 A of motor current, equal to 30 kW of usable shaft power with the appropriate motor. Acceleration demands are covered by a short-term capability of 100 A. The intermediate DC bus is regulated at 300 V ±15%, and the Ma setpoint scale of 0.075 V/A converts analog torque commands into proportional current. Thermal energy is removed by forced ventilation; the internal blower consumes 30 VA to maintain heat-sink temperature. Drive logic requires a minimum IRED current of 10 A, while the ±15 V auxiliary supplies can source 60 mA and 140 mA to external sensors, feedback cards, or gating circuits.
The power stage releases 400 W of heat under full load, so cabinet airflow and spacing must accommodate that loss. Reliable operation is permitted up to 55 °C ambient and installation altitudes of 1000 m without current derating. The IP10 housing limits protection to dry, enclosed panels, so exposed mounting is not recommended. The module has a mass of 10.5 kg, and its power terminals remain compatible with standard Indramat supply racks. When cooling airflow is interrupted, the unit’s thermal monitoring inhibits pulses once heat-sink temperature exceeds a safe limit, helping protect the power transistors.
