Product Description:

The TDM 1.2-050-W1 is a servo drive module manufactured by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It interfaces between a regulated DC bus and synchronous motors, shaping current and voltage so that motion axes can follow programmed profiles in assembly, packaging, and material-handling equipment. Installed on a common mounting rail, the module receives set-point data from the higher-level controller and applies closed-loop algorithms that regulate motor torque and speed for repeatable positioning cycles. The module is intended for cabinet-mounted motion systems that use a shared power infrastructure.

The drive supplies a continuous phase current of 45 A, allowing connected motors to deliver rated torque without thermal overload, while its continuous output power is capped at 15 kW for sustained production duty. Energy is drawn from a common intermediate circuit held at 300 V DC. Internal losses are managed by forced ventilation; the integrated blower consumes 30 VA and directs air across heat-dissipating components so that the total power loss stays within 250 W. For brief accelerations, the module can pass a peak current of 50 A, and the same 50 A current is used as the rating for protective devices and busbars. Humidity Class F materials and an Insulation Category C design separate power tracks from the grounded housing to withstand industrial contamination.

Environmental limits complement the electrical profile. The unit operates without derating up to 55 °C ambient and may be mounted at altitudes to 1000 m where cooling air density remains adequate. A basic enclosure rated IP10 protects internal parts from accidental contact while permitting airflow. The aluminum chassis stands 105 mm high and extends 390 mm into the cabinet, dimensions that permit dense stacking alongside other modules. The housing supports cabinet installation while leaving a clear path for forced-air cooling.
