Product Description:
The TDM 4.1-030-300-W1-220 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It operates as the power interface between CNC or PLC motion commands and the torque-producing windings of an Indramat PM synchronous motor. It converts intermediate-circuit energy into controlled three-phase output to keep axis motion precise in industrial automation cells. This arrangement lets the control system regulate motor torque and speed with repeatable response during positioning and contouring tasks.
This module delivers a continuous output current of 25 A, while its nominal current limit is 30 A. These values describe the thermal load that the internal bus bars and semiconductor switches can withstand without derating. A sustained mechanical output of 9 kW is possible when the DC link is maintained at 300 VDC, allowing the drive to support medium-frame machining spindles or gantry axes. Forced ventilation channels air across the heat sink, and residual power loss is 175 W under rated load. Peak current matches the nominal value, so short-term overload capacity depends mainly on system inertia rather than additional current margin. Internally, Class C insulation separates live conductors from the grounded chassis. The housing stands 390 mm tall and leaves only 70 mm of cabinet width, so multiple axes can fit on a standard DIN rail.
Auxiliary cooling hardware is energized by a fan supply of AC 220 V, and overcurrent protection for that blower is provided by a 0.315 A time-lag fuse. Safe operation is specified up to an ambient temperature of 55 °C and a mounting altitude of 1000 m without additional derating. The open-frame construction carries an enclosure rating of IP10, so the module is intended for installation in clean control cabinets away from accidental contact. With a mass of 8 kg, the unit is manageable during panel installation, and its compact form helps preserve cabinet space for cable routing and filter components.
