Product Description:

The TDM 1.4-050-300-W1-000 belongs to the TDM Servo Drive Modules series produced by Bosch Rexroth Indramat. As an adjustable servo drive module, it interfaces between a motion controller and an Indramat permanent-magnet motor to regulate torque, speed, and position in automated machinery such as gantry axes, packaging stations, and material-handling lines. By converting DC link energy into three-phase output, the unit supports closed-loop control tasks that require precise and repeatable motor behavior. In operation, it serves as the power stage that turns control commands into regulated motor current for accurate axis movement. That allows the connected motor to respond quickly to speed changes and position corrections.

The drive’s link circuit is stabilized at DC 300 V, giving the inverter stage enough voltage headroom for rapid acceleration and regenerative braking. A rated current of 50 A is the continuous output the module can deliver without thermal derating. The chassis is 390 mm wide and 100 mm high, which helps it fit low-profile control enclosures while leaving room for side-mounted power terminals and airflow passages. This size also supports cabinet layouts where several modules are installed close together. An integrated built-in fan moves ambient air across the internal heat sink to remove switching losses during heavy-duty operation.

Overall cabinet depth is limited to 320 mm, so the module can be installed in shallow panels without changing standard rail layouts. The cooling blower is powered within the unit by the internal auxiliary supply, so no separate fan wiring or external 24 V source is required. Classified as an AC Servo Controller, the module supplies three-phase currents that follow command signals from Indramat CNC or PLC-based command cards. The internal fan supply reduces the number of external connections needed at the module. This arrangement keeps the surrounding cabinet wiring simpler when multiple axes are mounted side by side.
