Product Description:

The TDM 1.2-100-300-W1-000/S105 servo drive module is built by Bosch Rexroth Indramat and placed within the TDM Servo Drive Modules series. As a regulated power stage, the unit interfaces between an Indramat supply module and a permanent-magnet motor to deliver controlled armature current and velocity feedback in industrial automation lines, packaging cells, and material-handling axes. It converts shared DC bus energy into a programmable three-phase output and coordinates precise motion while protecting connected motors during continuous duty. This arrangement suits cabinet-based motion systems that use a common DC link for multiple axes.

During continuous operation, the module supplies 65 A of armature current, which marks the thermal limit for long-duration duty cycles. For brief accelerations, it can follow the type current of 100 A without exceeding semiconductor stress. The shared bus delivers 300 V DC, and the drive converts it into three-phase power up to 30 kW for mid-sized servo motors. Internal thermal losses remain limited to 400 W, allowing the built-in fan to remove heat from the power section. This fan is powered by energy generated within the unit, so no external blower wiring is required. Insulation category C describes the creepage and clearance distances inside the power section. The control board draws 140 mA from the +15 V rail and 60 mA from the -15 V rail, which should be considered when sizing the associated supply module.

Operating limits include an upper derated temperature of 55 °C and a service ceiling of 1000 m above sea level. The open-style housing has an IP10 protection rating, so it must be installed inside a cabinet with filtered airflow that meets the humidity restrictions of class F. With a mass of 10.5 kg, the module supports stable mounting in high-speed machines. Cabinet placement should also leave enough clearance for the internal cooling path and routine electrical connections.
