Product Description:

The TDM 1.2-030-300-W0/S100 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. This module is designed to regulate torque and speed in synchronous and asynchronous motors used in automated assembly lines, packaging equipment, and material-handling stations. By regulating the available supply into controlled DC-link energy, the drive provides the closed-loop current control required for responsive motion tasks. In automated equipment, it helps maintain stable torque delivery during starts, load changes, and steady-state running.

During continuous operation, the unit supplies a motor phase current of 25 A. It can deliver a continuous mechanical output of 9 kW, which supports medium-power axes such as conveyor or spindle drives. The internal DC bus is maintained at 300 V (±15%), and the control section uses that level to regulate PWM output to the motor. Heat is removed by natural convection, so cabinet airflow must remain unobstructed. The housing has an IP10 enclosure rating, which provides protection against accidental finger contact but no sealing against dust or liquids. Because the enclosure is open to dust and liquids, the module is better suited to protected electrical cabinets than exposed machine surfaces.

Short-term transients are accommodated with a peak phase current of 30 A, allowing rapid acceleration without immediate current saturation. Safe operation is permitted up to an ambient temperature of 55 °C, and installation altitude can reach 1000 m before output reduction is required. At the rated continuous current, the drive dissipates 160 W of power loss, which should be considered when planning enclosure ventilation. The overload margin supports brief demand spikes that occur when a driven axis starts moving or recovers from a process disturbance. The unit also uses a C-class insulation system and has a mass of 9 kg.
