Product Description:

The TDM1.4-100-300-W1/00 is a servo drive module manufactured by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. Installed in control cabinets, the unit works as the power stage between the DC link of Indramat supply modules and synchronous or induction servo motors. By modulating voltage and current, it provides the closed-loop motor control needed for positioning tables, tool spindles, and other motion axes in automated machining and material-handling lines. Its slide-in module format also allows straightforward integration into cabinet-based drive systems.

During continuous operation, the drive can source up to 65 A to the motor windings, enabling high stall torque without thermal overload. Its power section is rated for 30 kW of sustained mechanical output, making it suitable for medium-power axes such as gantry carriages or large conveyors. Losses appear as approximately 400 W of heat, so cabinet airflow or external cooling must remove this heat to keep internal temperatures within an acceptable operating range. The housing has an IP10 protection rating, so it is intended for installation in clean electrical enclosures rather than exposed areas. Operation is permitted in surrounding air up to 55 °C, which should be considered when planning ventilation around the control rack.

The module maintains full current capacity up to 1000 m above sea level before derating is required, because higher elevation reduces cooling effectiveness. It is assigned to the Class F humidity group, so it can be used where relative humidity reaches 85 percent without condensation. The unit has a mass of 10.5 kg, which should be considered when selecting slide rails and retaining hardware for high-duty cabinet installations. Proper support helps keep the module stable during repeated machine motion and vibration inside the enclosure.
