Product Description:

The TDM 1.2-030-300-W1-220/S100 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. Designed as the intermediary between a shared DC supply and a motor, the module regulates armature current and voltage so that axis motion mirrors command values issued by the control system. It handles commutation, current limiting, and fault monitoring inside the drive, which helps maintain stable motion during speed changes, positioning moves, and load variations. In automated machinery, that behavior supports repeatable acceleration and deceleration while helping the motor respond predictably to command changes from the higher-level controller. It is suited to multi-axis equipment where several drives share a common DC source.

This module is rated for a continuous current of 30 A, providing a sustained output capability of 9 kW without exceeding thermal limits. The internal link circuit operates at DC 300 V, so the drive must be installed in racks that supply that bus level and match the electrical requirements of the connected axis. Under rated load, the electronic section dissipates 190 W of power loss, which must be considered when cabinet ventilation is planned. The housing has an IP 10 rating, so it blocks large accidental contact objects but still requires installation inside a protective enclosure. The module has a mass of about 10 kg, which supports stable mounting on the drive rack during machine operation. Front-access installation also depends on keeping wiring and neighboring modules arranged so air can move and terminals remain reachable.

Thermal management is provided by a built-in fan that draws 30 VA from a dedicated AC 220 V feed, removing heat generated by semiconductor switching and magnetic components. Because the cooling circuit is self-contained, external blowers are not required, although open space must be kept around the airflow path so exhaust air can leave the cabinet area freely. The separate fan supply keeps cooling available even when the power stage is not delivering full output. Airflow from the fan moves heat away from switching components and nearby magnetic parts, reducing localized hot spots inside the rack. The drive meets Category C insulation standards, indicating that its internal insulation system is intended for the electrical stress present in servo drive links. This is important in cabinets where neighboring modules add heat to the same enclosure space.
