Product Description:

The TDM 2.1-030-300-W0 is manufactured by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. It operates within multi-axis machining centers, printing lines, and assembly cells, where it supplies controlled current to Indramat permanent-magnet motors for accurate movement and synchronized process timing. The module is intended for servo applications that require stable current control, repeatable response, and synchronized motion across multiple machine axes. This makes it suitable for machine sections where several drives must respond together under shared control.

Its continuous output capability is 25 A, allowing the connected motor windings to receive steady torque without thermal overload. The module delivers up to 9 kW of electrical power drawn from a 300 VDC DC bus. Drive current is monitored through the MA terminals, and the calibrated gain of 0.250 V/A lets the control electronics translate shunt voltage into real-time current feedback. Short-term load spikes are handled with a peak current of 30 A, and a minimum adjustable current setpoint of 3 A supports fine motor detent force. Internal losses stay at 160 W under nominal conditions, the unit draws 60 mA from the -15 V supply and 140 mA from the +15 V supply for its analog processing stages, and the housing mass is 10 kg.

Thermal management relies on natural convection, so cabinet airflow must remain unobstructed. The module retains its full ratings up to 45 °C, and operation can extend to 55 °C with linear derating. Its enclosure carries an IP10 protection rating, restricting use to clean, closed electrical rooms where only vertically falling particles are present. Mounting elevations may reach 1000 m without performance adjustment, after which current limits must be reduced to accommodate lower air density. The link voltage is produced externally, so power-loss heat of 160 W represents the primary internal load on ambient temperature.
