Product Description:
The TDM 7.1-030-300-W1 servo drive module is produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It converts regulated DC energy into three-phase output for synchronous or induction servomotors in automated machine tools, packaging lines, and material-handling cells. By integrating current control, protective monitoring, and communication with the higher-level controller, the module acts as the power stage between the motion processor and the motor, supplying torque commands while supervising thermal and electrical limits. This arrangement allows the drive to respond quickly to command changes while maintaining stable motor operation during repeated acceleration and deceleration cycles.
With a continuous output of 12 A, the TDM 7.1-030-300-W1 can sustain steady-state motor torque without overheating. During rapid indexing or startup, it delivers up to 30 A briefly, giving extra acceleration headroom before the current-limit circuit intervenes. The internal power section is energized from a 300 V DC bus supplied by a compatible supply unit, and it can deliver a continuous output power of 9 kW to the connected axis. Heat generated by the switching devices is removed by forced ventilation, so cabinet airflow must remain unobstructed to keep semiconductor junction temperatures within a safe operating range. That combination is useful on axes that need steady running torque with short bursts for positioning moves.
The housing carries an IP10 rating, indicating finger protection but no sealing against dust or dripping water, so installation is expected inside an enclosure. Reliable operation is permitted up to 55 °C ambient and at altitudes not exceeding 1000 m; above these thresholds, derating or additional cooling is required. Power dissipation at rated load is 135 W, a value used to size cabinet fans and verify that the forced-air path can evacuate waste heat. Adequate spacing from adjacent modules and the system power supply also helps maintain stable internal temperatures.
