Product Description:
The TDM 2.1-30-300-W1/220 drive module is manufactured by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. It is a transistorized DC-link servo amplifier that receives energy from an Indramat supply unit, converts that energy into a controlled three-phase output, and supplies it to synchronous or asynchronous servo motors. By regulating current and voltage, the module supports closed-loop speed and position control for axes used in packaging machinery, transfer lines, and general automation cells. This operating method helps the drive respond to changing load demands while maintaining stable motor control.
The power stage delivers a continuous output of 30 A, which corresponds to a sustained mechanical output of 9 kW when paired with a properly sized motor. A link circuit held at 300 V DC serves as the intermediate energy store from which the motor phases are pulsed. To control internal temperature, the unit relies on forced ventilation; its integral fan consumes 30 VA and is protected by a 0.315 A, 250 V F5 miniature fuse connected to a 220 V AC tap. During operation, thermal and switching losses total 190 W, so cabinet airflow must remove that heat. Auxiliary logic rails draw 140 mA at +15 V and 60 mA at -15 V to supply sensors and gate circuits.
Allowable site conditions include a maximum ambient temperature of 55 °C and installation heights up to 1000 m above sea level. The electronic assembly uses humidity classification F and insulation category C, which set spacing and creepage distances when multiple amplifiers are installed together. A protection rating of IP10 means the module is protected against accidental finger contact but must remain inside a ventilated control enclosure because it is not protected against water ingress. Overall weight is 10 kg, which keeps handling manageable during installation. The enclosure should provide a clear airflow path so internally generated heat can leave the module during continuous operation.
