Product Description:
The TDM 1.4-100-300-W1-100 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It functions as the power and control interface between an Indramat supply unit and a compatible servo motor, converting the DC link energy into controlled three-phase output that governs motor torque and speed. By integrating speed regulation and fault monitoring, the module supports precise positioning and coordinated motion sequences in automated machinery. This arrangement lets the supply unit remain separate from the axis electronics while the module handles current delivery and drive supervision close to the motor-control loop.
Thermal management is handled by a built-in fan, and the air mover draws its power from an internal supply, eliminating the need for an external blower circuit. The drive is engineered for applications that demand up to 100 A of armature current, so its power devices and bus bars can carry that continuous load without derating. A stabilized link circuit of 300 VDC feeds the output stage, and this fixed voltage supports consistent dynamic response across the full speed range of standard Indramat servo motors. The housing carries an IP10 protection class, which guards against accidental finger contact with live parts while keeping the enclosure open enough for airflow from the fan.
Reliable operation is maintained up to 55 °C ambient, provided cabinet ventilation prevents recirculating hot air. Installation heights can reach 1000 m above sea level without adjustment because semiconductor cooling still supports rated current at that altitude. The drive meets Class F humidity requirements, so internal components tolerate periodically high moisture levels found in many production areas. It is intended for installation inside control cabinets, where proper air movement helps maintain thermal stability and electrical performance. Cabinet layouts should leave enough clearance for cooling air so heat from neighboring devices does not build up around the module.
