Product Description:

The TDM 2.1-030-300-W0/S101 servo drive module is produced by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. Used with synchronous motor axes, the unit converts DC-bus energy from an Indramat supply into a regulated, phase-accurate output that follows programmed torque or velocity commands. In industrial automation cells, this module links numerical controls to mechanical motion and provides precise current regulation for machining spindles, transfer lines, and material-handling gantries. This operating role suits applications that need stable torque delivery during changing load and speed conditions.

The drive delivers a continuous output current of 25 A, which is the maximum line-to-line current the power stage can sustain continuously without exceeding thermal limits. That current corresponds to a continuous mechanical power capability of 9 kW when the connected motor runs at rated speed. Its intermediate circuit is stabilized at 300 VDC, giving the controller a fixed energy reservoir from a shared supply unit. During nominal operation, the electronics dissipate 160 W of heat, so the housing relies on natural convection and does not use forced-air fans. The regulated DC link helps keep motor response consistent during continuous operation, especially where several axes share a common supply section. Operation is allowed in environments designated Humidity Class F to reduce the risk of condensation on sensitive control boards, and insulation materials follow Category C for reinforced dielectric spacing.

Short-term overloads are handled with a peak current of 30 A, permitting rapid acceleration without triggering overcurrent trips. Ambient temperatures up to 55 °C are permissible when vertical mounting allows air to rise across the heat sink. Installation heights may reach 1000 m without derating, supporting standard factory mezzanines. The enclosure has an IP10 rating, so it must be installed inside a closed cabinet to limit contact with foreign objects. Cabinet installation is necessary because the housing is not intended for open mounting where accidental contact can occur. The module has a shipping mass of 10 kg, and its convection-based layout avoids the added bulk of blowers or ducting.
