Product Description:

The TDM1.2-50-300-W1-220/S102 is a servo drive module manufactured by Bosch Rexroth Indramat and supplied within the TDM Servo Drive Modules series. The unit works as the power interface for an Indramat servo axis, providing the regulated energy and control response needed for accurate motion in automated machinery. In modular drive racks, it supports coordinated axis operation by processing incoming power, supervising current flow, and responding to commands from higher-level motion control systems.

The drive maintains a continuous armature output of 45 A, allowing it to support motors that require sustained torque during regular operation. Its thermal design also supports a rated mechanical power of 15 kW, which indicates the nominal output level associated with the connected motor under normal load conditions. Inside the power section, energy is stored on a link bus held at 300 VDC, giving the controller a stable voltage source for pulse-width modulation. Cooling is handled by forced ventilation, and the external blower operates from a 220 VAC auxiliary supply. During conversion, losses are limited to 250 W, which helps keep internal heat generation manageable during continuous use.

Short-term dynamic demand is covered by a peak phase current of 50 A, allowing the module to handle brief acceleration events above the continuous current level. Operation is permitted at ambient temperatures up to 55 °C, and the housing has an IP10 enclosure rating, so the module is intended for installation inside a suitable control cabinet. The control electronics draw current from internal low-voltage rails to support the analog interface and sensor circuitry without placing excessive demand on the supply section. The module has a mass of 10 kg, which keeps rack installation straightforward while maintaining a solid mechanical form.
