Product Description:

The TDM 1.4-100-300-W1-0 servo drive module belongs to the TDM Servo Drive Modules series from Bosch Rexroth Indramat. It serves as the power interface between numerical controllers and three-phase motors, producing regulated phase currents so automated axes follow commanded torque and speed profiles. By rectifying mains input and modulating the resulting DC link, the unit supports dynamic motion control for machine tools, packaging lines, and material-transfer stations in the high-current drive class. Its drive electronics include firing circuits, current monitors, and integrated diagnostics that report real-time fault states and operating data to the supervisory controller over the series backplane.

A self-contained built-in fan moves air across the heat sinks, removing switching-loss heat without external ducting. The internal link voltage is rated at 300 VDC, and the permissible variation window of ±15% lets the module tolerate moderate supply fluctuations. During acceleration or braking, the current regulators can deliver up to 100 A of phase current, matching medium-power servo motors. An enclosure protection level of IP10 indicates that solid objects larger than 50 mm are blocked while airflow remains unrestricted for thermal management.

Continuous operation is permitted up to 55 °C ambient when derating rules are observed, and installation heights may reach 1000 m above sea level before output must be reduced. The module is approved for environments that meet Humidity Class F, so condensation must be prevented during storage and service. The DC bus capacitors provide energy storage for regenerative peaks, while the internal cooling path helps keep component temperatures within the normal operating range. This arrangement supports stable current response during changing load conditions.
