Product Description:

The TDM 2.1-030-300-W1-000/S105 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. Designed to regulate motor torque and speed in automated machinery, the unit converts a fixed DC link into controlled three-phase output and supplies feedback-oriented current to connected servomotors. By integrating its own cooling hardware and a standardized power section, the drive forms a compact control element inside multi-axis Indramat drive racks used in packaging, material handling, and assembly lines. It is intended for cabinet-based drive systems that use a shared DC bus and require stable axis control during changing load conditions.

Its electrical performance centers on a continuous phase output of 30 A, and the type current is the same. This capability corresponds to a mechanical output of 9 kW when the internal link circuit is held at 300 V DC. The peak current matches the continuous current, so short acceleration bursts do not raise the current limit beyond that level. An internal built-in fan removes heat; the blower draws 30 VA and is powered directly from the drive, so no external wiring is needed. Power losses at rated current reach 190 W, and the control electronics draw current from the +15 V and -15 V auxiliary rails for interface logic and sensor evaluation.

The module operates up to 55 °C ambient temperature and can be mounted at elevations to 1000 m without derating. The housing has an IP10 rating, which provides basic protection against accidental contact and requires installation inside an enclosure where dust or liquids are controlled. The complete assembly weighs 10 kg, so it can be inserted into a standard sub-rack without excessive handling load. Cabinet airflow should still be provided so the internal cooling path can discharge heat efficiently during continuous operation.
