Product Description:
The TDM1.2-050-220-300-W1 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. Installed in a multi-axis rack, it receives a stabilized DC bus from a supply unit and generates phase-controlled output for a synchronous motor. It is intended for rack-based motion systems that separate the supply, control, and drive functions into coordinated modules. This layout suits systems where several axes share one power infrastructure and are mounted side by side. By providing closed-loop current control, the module supports precise position and velocity commands in machining centers, printing presses, and automated transfer stations.
The module can deliver a continuous phase current of 45 A, and at this rating the power stage sustains a mechanical output of 15 kW. Internal dissipation during full-load operation is limited to 250 W, so cabinet airflow must remove this heat to avoid temperature drift. The cooling fan is supplied directly from a dedicated line at 220 VAC and is protected by a 0.315 A/250 E miniature fuse that trips if the blower stalls. Command scaling is handled through a current feedback network with an Ma ratio of 0.050 V/A; this lets the controller translate 1 V of sense voltage to 20 A of true motor current. For signal conditioning, the logic section draws 950 mA from the +24 V rail, while the ±15 V monitors consume 140 mA and 60 mA, respectively. The minimum settable current is 15 A, allowing fine torque regulation at low load.
The power electronics are specified for ambient temperatures up to 55 °C, provided the mounting altitude does not exceed 1000 m. Protection is classified as IP10, indicating that the module must be installed inside a closed electrical cabinet to avoid conductive dust or fluid ingress. The open module format also relies on the surrounding enclosure for touch protection and contamination control. With a mass of 10 kg, the unit remains manageable during cabinet installation, and its chassis provides enough thermal mass to moderate short-term load surges.
