Product Description:

The TDM-1.2-030-300-W1 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It functions as the regulated power stage between a supply module and a synchronous or asynchronous motor, converting the shared DC link into controlled three-phase output while processing motor feedback. This role places the unit at the center of automated machine tools, packaging lines, and material-handling stations where accurate speed and torque control are required.

Rated for a continuous output current of 30 A, the module can deliver up to 9 kW of mechanical power to the connected motor when the internal DC link is maintained at 300 VDC. Forced ventilation moves cooling air across the heat sink to keep semiconductor junctions within limits, and the drive tolerates humidity that meets class F while insulation materials conform to category C. During operation, the electronics dissipate 190 W as heat, a figure that influences cabinet airflow calculations. An enclosure classification of IP10 blocks objects larger than 50 mm, so the unit must be installed inside a protected panel. The -15 V and +15 V auxiliary rails draw 60 mA and 140 mA, respectively, to supply encoders and logic, and temperature sensing is handled by a 20 kΩ thermistor embedded in the heat sink.

The thermal design supports full rating up to 55 °C ambient, provided the mounting altitude stays below 1000 m. A ready relay contact is available for system interlocks and can switch up to 24 V / 1 A when the drive indicates operational status. Overall power losses, auxiliary rail demand, and the forced-air path affect cabinet fan sizing, while a mass of 10 kg allows installation on DIN rails or backplates. Closed-loop temperature monitoring prevents overtemperature faults during continuous duty.
