Product Description:

The TDM 1-2-100-300W servo drive module is produced by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. The unit functions as a closed-loop power stage for motion axes in automated production cells, receiving commands from higher-level controls and feeding synchronized current to connected servomotors. By managing acceleration, braking, and steady-state torque, it allows machine builders to achieve repeatable positioning and speed regulation across conveyors, gantries, and machining heads. This operating role makes the module suitable for coordinated axes that must respond consistently during frequent speed changes and stop-start cycles.

It delivers a continuous output current of 65 A, allowing motors to sustain high torque during extended duty cycles, and it can rise to a peak of 100 A for short acceleration bursts. The internal link circuit is rated at 300 V DC ±15%, which sets the required bus voltage range for compatible power supplies. Under nominal load, it can furnish 30 kW of mechanical power while dissipating only 400 W as heat, and forced ventilation moves cooling air through the heat sink. The control electronics also draw a supplementary 15 V rail at 140 mA for logic and sensor functions, which helps separate low-power circuitry from the main power section.

For installation, the drive is permitted to operate without output derating at ambient temperatures up to 55 °C and at elevations up to 1000 m above sea level. The electronics are prepared for environments categorized under humidity class F, supporting insulation performance in air containing as much as 90% relative moisture. An enclosure rating of IP 10 indicates basic protection against accidental contact, so the module is intended for mounting inside a closed control cabinet with a clear fan path. The assembly weighs 10.5 kg, which supports manageable handling during installation and allows dense stacking of multiple axes on a backplane without overloading typical panel structures.
