Product Description:

The TDM 2.1-030-300-W0/S102 is a servo drive module from Bosch Rexroth Indramat in the TDM Servo Drive Modules series. It interfaces between the DC bus and a matched motor, regulating current loops and monitoring faults so that axes in automated machinery follow commanded speed or torque profiles. By conditioning power and supervising feedback signals, the unit relieves the higher-level controller of direct motor regulation and simplifies the retrofit of legacy mechanical systems. It is intended for applications that need predictable torque response and straightforward integration with existing drive systems.

During steady operation, the module delivers a continuous current of 25 A, allowing the connected motor to hold rated torque without overheating. For short acceleration bursts, it can supply 30 A, which also serves as the type current used for cable and fuse sizing in the installation. The DC bus is regulated at 300 V ±15 %, which keeps motor back EMF and switching stress within the intended range. A continuous power capability of 9 kW suits medium machine tools and similar automation equipment. Internal dissipation is limited to 160 W, so cabinet heat removal must be considered during layout. The ±15 V auxiliary rails draw 15 mA each, and the signal electronics impose 60 mA and 140 mA loads, which helps keep the external supply requirement compact. These values fit a module sized for medium-duty axes that alternate between holding torque and brief acceleration peaks.

Thermal management relies on natural convection, so cabinet layouts must allow airflow around the heat-sink fins. The housing meets an IP 10 protection rating, which prevents finger contact with live parts and requires installation inside a closed enclosure. Reliable operation is permitted up to an ambient temperature of 55 °C and a mounting altitude of 1000 m; above these limits, derating or added cooling is required. The insulation category is C, matching the clearance requirements of the DC link. Its open enclosure style also makes cabinet placement important when nearby components produce additional heat. With a mass of 10 kg, the module remains manageable during installation and service.
