Product Description:
The TDM 1.2-050-300-W1-00 is a drive unit from the TDM Servo Drive Modules series manufactured by Bosch Rexroth Indramat. The module interfaces between the DC bus of an Indramat supply unit and a servo motor to regulate current and velocity within automated machinery. At 10 kg, it is light enough for panel mounting without additional support, and its built-in forced-air channel lets cabinet airflow reach the internal heat sinks. This layout helps the module fit compact control cabinets used for servo axes in automated production equipment.
The drive’s continuous phase output is 45 A, allowing long-term motor operation below thermal limits. For short duty peaks, it can supply a rated current of 50 A, giving extra torque during acceleration. A continuous power handling capability of 15 kW matches medium-frame servomotors used in packaging or material-handling equipment. The internal DC bus is stabilized at 300 VDC, so the connected supply must maintain that level for proper current control. Heat is removed by built-in forced ventilation, and the fan draws only 30 VA, which has little effect on overall system loading. Control electronics also require separate signal rails at -15 V and +15 V for normal operation.
During operation, the module dissipates 250 W of power, a value that should be considered when planning cabinet cooling. It can function in ambient temperatures up to 55 °C without derating, provided humidity remains within Class F limits and the installation altitude does not exceed 1000 m. The housing has an IP 10 protection rating, which means it should be installed inside a closed electrical cabinet to limit exposure to dust and accidental contact. Insulation category C supports safe electrical separation inside the module during normal drive operation.
