Product Description:
The TDM 1.2-050-300-W1-000/S100 belongs to the TDM Servo Drive Modules series produced by Bosch Rexroth Indramat. As a drive module, it delivers regulated DC power and control signals to synchronous or asynchronous motors used on automated production lines, material-handling stations, and packaging machines. By converting link-circuit energy into adjustable phase currents, the unit forms the interface between the plant’s supply section and the machine’s motion axis. This arrangement lets the module respond to speed and torque commands from the control system while keeping motor operation stable under changing loads.
During continuous operation, the drive can supply 45 A of motor current, corresponding to a thermal output capability of 15 kW at the motor terminals. These currents are drawn from a shared DC link that is maintained at 300 VDC, so the module must dissipate 250 W of internal power loss through its integral ventilation system. A separate fan draws only 30 VA, which limits the added load on the power supply. When rapid acceleration is required, the output stage can deliver a momentary 50 A peak, while the minimum adjustable setpoint of 5 A allows torque adjustment for light-load axes. Analog monitoring is provided through a ±1 mA measurement channel, and its full-scale value is scaled at 0.150 V/A so drive current can be read directly by external diagnostics without digital buses.
The module retains full ratings up to 55 °C, and performance is not derated when mounted at elevations to 1000 m above sea level. The open-frame housing carries a IP10 designation, indicating protection against accidental finger contact while still requiring installation in a switch cabinet for dust or liquid exposure. Control electronics draw 60 mA from the -15 V rail and 140 mA from the +15 V rail provided by the supply unit, while the temperature-sense output presents 20 kΩ to the supervisory circuit for straightforward thermal sensor wiring. With a weight of 10 kg, the module requires stable mounting inside the cabinet.
