Product Description:
The TDM 1.2-050-300-W1 belongs to the TDM Servo Drive Modules series manufactured by Bosch Rexroth Indramat. As a servo drive module, it supplies regulated DC link power and gating signals to matched motor controllers. This supports closed-loop speed and torque regulation in automated machinery and production lines.
The module draws 60 mA from its -15 V rail and 140 mA from the +15 V rail while offering an external ±15 V tap rated for 15 mA per rail to feed encoder or sensor electronics. Its continuous output current is 45 A, giving the connected motor stable armature excitation up to the rated thermal limit. That current supports continuous mechanical power delivery of 15 kW when the drive is paired with an Indramat permanent-magnet servo. The internal DC bus operates at 300 VDC ±15%, and the front-panel test point uses a scaling factor of 0.050 V/A so load current can be checked with a standard voltmeter. Minimum adjustable current is 15 A to help maintain stable operation at light load, and forced-ventilation cooling channels move cabinet air across the heat sink while the IP10 housing is intended for protected panel installation.
During rapid acceleration, the drive can supply a peak phase current of 50 A, after which it must return to continuous ratings to stay within an estimated power loss of 250 W. Operation without derating is permitted until the ambient temperature reaches 55 °C, and installations are limited to a maximum altitude of 1000 m so forced convection remains effective. The drive electronics share the cabinet ground through a molded bus bar, and the protection class allows open-frame mounting inside closed control panels. The unit has a mass of 10 kg, which requires secure support on a vibration-free backplane to maintain alignment of the plug-in edge connectors.
