Product Description:
The TDM 1.2-030-300-W1-000/S105 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It converts DC link energy into controlled three-phase motor current, supplying torque and speed commands to automation axes in machining centers, material-handling gantries, and similar equipment. The module combines an internal power section with monitoring circuits so the connected controller can issue precise current setpoints while the drive enforces them in real time.
The power stage delivers a continuous output of 30 A, which suits medium-frame servomotors that require steady armature current for rated torque. A link circuit voltage of DC 300 V is maintained across the intermediate bus, and this voltage supplies the energy used by the three pulse-width-modulated inverter legs. Internal losses reach 190 W under nominal loading, and heat is removed by a built-in fan that generates its own airflow, so no external blower connection is required. The insulation system is rated for Category C, indicating creepage and clearance distances suitable for industrial cabinets using a 300 V DC link.
The mechanical assembly weighs 10 kg, allowing direct panel mounting without additional support hardware. Reliable operation is permitted at ambient temperatures up to 55 °C and at installation heights up to 1000 m above sea level, which limits thermal stress on semiconductor junctions and magnetic components. Control wiring includes a ready-state contact rated for 24 V, 1 A so external PLCs can monitor drive availability. The auxiliary supply rails also support internal measurement circuits that draw 60 mA at -15 V and 140 mA at +15 V, helping maintain stable reference voltages for current feedback amplifiers and protection comparators during dynamic load changes.
