Product Description:
The TDM 1.2-030-300-W1-00 is a servo drive module produced by Bosch Rexroth Indramat and assigned to the TDM Servo Drive Modules series. It supplies regulated three-phase power to motors in machining centers, pick-and-place gantries, and other automated stations, translating motion commands from the controller into precise torque and speed on the axis. In a closed-loop motion system, the module sits between the controller and motor so electrical output follows commanded axis behavior with consistent response. Signal electronics draw 140 mA from the +15 V supply and 60 mA from the -15 V rail, supporting tachometer feedback and command circuits.
Its continuous, rated, and peak currents are all specified at 30 A, allowing the connected motor to draw steady current without derating or transient overshoot. The power section can deliver 9 kW continuously, which suits medium-frame servomotor requirements in regulated axis operation. An internal converter links to a DC bus held at 300 VDC ±15 %, so braking energy can be shared across multiple modules on the same supply. Thermal loads are removed by forced ventilation, and the integrated fan keeps heat sink temperature stable while total power dissipation remains limited to 190 W. For cabinet integration, the housing carries an IP10 protection rating, so the unit must operate inside a clean electrical enclosure.
The drive can operate in ambient temperatures up to 55 °C and may be mounted at elevations to 1000 m without output reduction. Humidity class F and insulation category C support reliable operation in moist or dusty workshops, where cabinet cleanliness and airflow still need to be maintained. The chassis mass of 10 kg makes the module easier to handle during panel installation and adds thermal inertia during short overload events. Stable cabinet airflow remains important when the drive operates near its upper ambient temperature.
