Product Description:
The TDM1.2-100-300-W1-000 is a servo drive module manufactured by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. Installed in control cabinets alongside CNC or PLC hardware, this module supplies regulated motor power and dynamic current loops that form the core of closed-loop motion axes. It functions as the interface between a shared DC link and individual motor windings, translating commanded velocity or torque references into precise phase currents for industrial automation equipment.
The drive can deliver a continuous phase current of 65 A, allowing sustained operation of medium-power servo motors without derating. At this current, the module supports a continuous shaft power output of 30 kW, matching the energy demands of packaging lines, gantry systems, or tool spindles. A link circuit voltage of 300 VDC ties the unit to a central supply, so the common bus stores regenerated energy during deceleration. Transient loads are handled by a peak current capability of 100 A, which covers rapid acceleration or shock torque events. Thermal energy generated by the power electronics is extracted by a built-in fan, and the residual heat appearing as 400 W of power loss must be removed by cabinet airflow to keep semiconductor junctions within safe limits. Humidity Class F and Insulation Category C indicate the permissible moisture content around the windings and the creepage distances between live conductors.
The module is specified for ambient temperatures up to 45 °C and can be mounted at heights not exceeding 1000 m above sea level, supporting expected cooling airflow and voltage derating margins. An enclosure rating of IP10 provides basic finger protection while relying on the control cabinet for full environmental sealing. With a mass of 10.5 kg, the unit can be rack-mounted without additional structural reinforcement. Storage temperatures extend to 85 °C, and the signal electronics draw 140 mA from the +15 V rail and 60 mA from the –15 V rail to power control logic and sensor interfaces.
